EV Tires: Why They Wear Faster and What Replacement Costs

Tires are the one consumable an electric car does not let you forget, and they are the one almost nobody prices before buying. The pitch that sells electric cars is a short maintenance list and cheap energy, and both of those are genuinely true. What the pitch skips is that when you delete oil changes, exhaust systems and most brake wear, the items that remain get larger as a share of the bill, and the largest of them is a set of tires that a heavy, instantly torquey car wears through faster than the gas car it replaced. That is not a flaw in electric cars. It is a line item that moves from background noise to the front of the budget.

This teardown prices that line item. It covers why mass and torque wear tread faster, what an EV-specific or low rolling resistance tire actually is and what you trade for it, how rotation and alignment change the arithmetic, and where tire spend lands once you fold it into cost per mile. Our cost per mile teardown and our maintenance schedule teardown already argue the wider running cost case, so this one links them rather than repeating them. Every figure below is an illustrative placeholder held consistent across the article, and you can run your own version in our cost calculator.

Why tires became the headline consumable on an electric car

On a combustion car, tires are a background expense. They sit behind fuel, behind oil services, behind the slow accumulation of belts, plugs, exhaust parts and the eventual transmission or emissions repair that arrives somewhere past the warranty. Nobody builds a spreadsheet around them because so many larger numbers are in the way. Delete most of those numbers and the picture inverts. An electric car has no oil, no plugs, no exhaust, no fuel system and barely uses its friction brakes, so the consumables that survive stand alone.

Tires survive, and they get worse rather than better. The same design decisions that make an electric car quick and efficient also make it heavy and abrupt at the contact patch, so the surviving consumable is also the accelerated one. That combination is what moves tires from a line most owners ignore to something worth planning for at purchase. The practical consequence is not that electric cars are expensive to run, because the energy saving usually still wins comfortably. It is that the running cost is shaped differently, with a bigger share sitting in four black rings that wear on a schedule your right foot controls.

What actually makes an electric car eat tires faster

Two mechanisms do almost all of the work, and it helps to keep them separate because they respond to different countermeasures. The first is mass. A traction battery is heavy, and the whole vehicle is engineered around carrying it, so an electric car frequently weighs noticeably more than a similarly sized combustion car. Mass is not a comfort penalty here, it is load on rubber. Every time the car turns, brakes or accelerates, the tread blocks deform and slide microscopically against the road, and more weight means more of that.

The second is torque delivery. An electric motor produces its full twisting effort from a standstill with no build-up, no gear selection and no delay. That is the characteristic people love, and it means the tread is asked to transmit a large force at exactly the moment it has the least help from momentum. A gas car with the same peak output builds toward it, which gives the contact patch a gentler ramp. Neither mechanism is a defect. Both are simply physical facts that show up as tread depth falling faster than owners expect.

Curb weight: load the contact patch never gets a break from

Weight matters at every moment, not only during hard driving, which is what makes it the harder of the two factors to drive around. A heavier car pushes the tread into the road with more force at all times, so the rubber runs warmer, deforms more through each rotation, and abrades faster during the small slip that every cornering and braking event involves. Nothing about smooth driving removes that. You can moderate how much torque you demand, but you cannot moderate what the car weighs.

Weight also multiplies the cost of every other tire mistake. An alignment that is slightly out of specification scrubs tread on a heavy car faster than on a light one, because the sideways force doing the scrubbing scales with the load. Underinflation does the same, flexing the sidewall harder and cooking the shoulders. On a light car those errors cost you a few thousand miles of tread. On a heavy one they can cost a meaningful fraction of a set. That is why the maintenance items in this teardown matter more on an electric car than the same items ever did on a gas one.

Instant torque: the wear you create without feeling it

The torque effect is the one owners can actually control, and the reason it goes unnoticed is that electric cars make hard acceleration feel effortless. There is no engine note climbing, no gearchange, no drama at all. Pulling away from a light briskly in an electric car feels roughly like pulling away gently, which means the feedback loop that used to tell a driver they were being hard on the car has been quietly removed. The tread still knows. It is the only part of the system that has to convert all that torque into forward motion.

At the margin between grip and slip, tread rubber shears and abrades. You do not need visible wheelspin for it to happen, and on a damp road it happens sooner than you think. Traction control intervening is a signal that the tread was doing more work than it wanted to. None of this means an electric car should be driven timidly. It means that a driver who habitually uses the full pull from every stop is choosing a shorter tire life, and it is fair to know the price of that choice rather than being surprised by it.

Regenerative braking shifts wear from pads to tread

Regeneration is one of the best things about driving an electric car and it genuinely saves money on brake components, so this section is a nuance rather than a warning. When you lift off, the motor acts as a generator and its resistance slows the car while returning energy to the pack, a mechanism our teardown on how regenerative braking works covers properly. Because friction brakes barely get used, pads and rotors on an electric car can last far longer than on a comparable gas car.

The nuance is where the deceleration is applied. Friction brakes act at all four corners; regeneration acts through the driven wheels only. So slowing that used to be spread across four contact patches now concentrates on two on a single-motor car. In everyday driving the effect is modest, and the brake savings are real money that partly offsets the tire spend. What it does argue for is disciplined rotation, since anything that loads one axle differently is precisely the imbalance rotation exists to even out. Smooth, early lifting also scrubs less than abrupt one pedal stops.

What an EV-specific tire actually is

The phrase gets used loosely, so it is worth defining by function rather than by marketing. When a tire is presented as suited to electric vehicles, it usually means the design has been pushed in some combination of four directions: a higher load carrying capability for the extra mass, construction and compound aimed at low rolling resistance to protect range, tread pattern and internal damping chosen to reduce noise in a cabin with no engine to mask it, and sometimes a compound intended to cope with high torque without shredding.

Those are real engineering goals, but none of them is a category that a regulator defines, and no badge on a sidewall guarantees any particular outcome. Plenty of conventional tires meet the load and speed requirements of an electric car perfectly well, and plenty of tires described as suitable for electric vehicles are ordinary products with a marketing layer. The useful screen is not the label. It is whether the tire matches the size, load index and speed rating on your door jamb placard, and then how it performs on the characteristics you personally care about most.

Low rolling resistance and the trade you are making

Rolling resistance is energy lost as the tire flexes under load and recovers, released mostly as heat. A low rolling resistance design reduces that loss through compound chemistry, carcass construction and tread geometry, so more of what leaves the battery reaches the road. Because so many electric cars leave the factory wearing these tires, this is often the fitment owners compare everything else against, and switching away from it is one of the most common reasons an owner reports losing range after a tire change.

The trade is genuine and worth stating plainly. The properties that reduce rolling losses tend to pull against wet grip and ultimate cornering bite, and in some designs against tread life too. A tire that saves you energy is not automatically a tire that lasts longer, and it may not be the one you want on a wet commute. Our teardown on maximising EV range treats tire choice as one of the larger levers available, and it is, but grip is a safety characteristic and efficiency is a cost characteristic. Weigh them in that order.

Load index, speed rating and why fitment is not negotiable

This is the part of tire choice where preference stops and requirement starts. Every vehicle carries a placard, usually on the driver door jamb, listing the tire size, the load index and the speed rating the car was designed around, along with the recommended cold inflation pressures. The load index encodes how much weight each tire is rated to carry, and on a heavy electric car it is frequently higher than a casual size match would suggest. Fitting a tire with a lower load index than specified is not a cost saving, it is an engineering failure waiting for a hot motorway day with a full car.

Speed rating matters for the same reason: it reflects the construction’s ability to handle sustained heat and deformation. Some electric cars also specify particular fitments because of noise damping, tire pressure sensor compatibility or suspension calibration. The practical instruction is simple. Read the placard, take a photo of it, and make the fitter confirm the replacement meets or exceeds the size, load index and speed rating written there. Where a shop suggests a deviation, ask which specification they are working from and get the reasoning in writing.

Foam liners, cabin noise and why quiet tires cost more

An electric car removes the loudest thing about a car, which promotes everything else. Road noise that used to be masked by an engine now arrives unaccompanied, and tire roar becomes the dominant sound at speed. Manufacturers respond in two places: extra sound insulation in the body, and tires designed to generate and transmit less noise. Some factory fitments include a layer of foam bonded inside the tire, which damps the air cavity resonance that produces the low droning hum on coarse surfaces.

Those tires cost more, and they change the repair conversation. A foam-lined tire is often more expensive to replace and can be more awkward to repair, and fitting a conventional tire in its place will usually make the cabin noticeably louder even if every other characteristic is fine. That is a legitimate reason some owners stay with the original specification despite the price. It is also a reason to ask, before you buy, whether the tire on your car has a liner, because discovering it at replacement time is how a budget gets broken.

What a replacement set actually costs

Any specific price quoted in an article is out of date the week it is written, so treat the numbers here as arithmetic scaffolding rather than a quote. What holds is the pattern. Electric cars tend to sit toward the expensive end of their size class because larger wheel diameters are common, higher load indexes are common, and factory fitments often carry low rolling resistance construction or foam damping. A set for an electric crossover is frequently a bigger cheque than a set for a similarly priced combustion crossover.

This teardown uses an illustrative $1,000 for a fitted set of four, chosen because it is a plausible mid-range figure that keeps the later arithmetic legible. Real sets range widely on either side of that, and a small electric hatchback on modest wheels can be far cheaper while a large performance-oriented model on oversized wheels can be a multiple of it. The only number that matters for your budget is the one a local fitter quotes for your exact size, load index and speed rating, so get two or three before you assume anything.

The fitting bill: everything that is not the tire

Comparing tire prices alone is how people end up surprised at the counter, because a fitted set includes several charges that vary more between shops than the tires do. Mounting and balancing is charged per wheel. New valve stems or tire pressure sensor service kits are often recommended or required at the same visit, and sensor batteries eventually die, so a sensor replacement can land in the same bill. Disposal of the old tires carries a fee in most places. An alignment check is frequently sold alongside, and on a heavy car it is usually worth taking.

Add those up and the fitting side can be a noticeable fraction of the total, which is why the honest way to compare quotes is out the door rather than per tire. The illustrative $1,000 used throughout this teardown is an out the door figure for four tires fitted, balanced and disposed of, precisely so the cost per mile arithmetic later does not quietly understate itself. When you collect your own quotes, insist on the same basis or the comparison is not a comparison.

Rotation: the cheapest lever on the whole budget

If there is one habit that pays for itself on an electric car, it is rotation. Commonly specified somewhere around every 5,000 to 7,500 miles, or roughly twice a year for an average driver, rotation moves each tire through different positions so that wear averages across the set rather than concentrating in one pair. Front and rear axles carry different loads and do different jobs, and on a car whose driven axle handles both instant torque and most regenerative braking, the imbalance is larger than it was on a gas car.

The economics are lopsided in your favour. A rotation costs a few tens of dollars. The set it protects costs several hundred to well over a thousand. Skipping rotations does not usually destroy tires outright, it just means one pair reaches the wear bars while the other pair still has usable tread, and because you generally replace in matched pairs or full sets, that unused tread gets thrown away. This teardown assumes rotation every 6,000 miles at an illustrative $30, and treats it as non-negotiable rather than optional maintenance.

Alignment: the silent way to lose a set early

Alignment is not usually a fixed interval service, but it earns a check roughly once a year on a heavy car and immediately after any serious pothole or kerb strike. A wheel that points slightly wrong drags sideways across the road every single mile, and the tread pays for it. The reason this matters more on an electric car is the same reason everything else does: the scrubbing force scales with the load pressing the tire down, so the same misalignment costs more tread on a heavier vehicle.

The symptoms are subtle enough that people miss them for months. A wheel that is not centred when driving straight, a pull to one side on a flat road, an edge of tread that is visibly more worn than the rest, or a feathered pattern you can feel by running a hand across the tread blocks. None of that lights up a warning. Feel the tread by hand every few weeks, and if one edge is going faster than the other, book an alignment before you replace anything, because a new set on an unaligned car simply repeats the loss.

Tire pressure: the setting that pays twice

Pressure is the highest return five minutes in the whole of car ownership, and on an electric car it works on two budgets at once. Underinflation increases rolling resistance, which costs range, and it flexes the sidewall harder, which builds heat and wears the shoulders faster. Overinflation reduces the contact patch, which wears the centre band and costs grip. The correct figure lives on the door jamb placard, not on the tire sidewall, which shows a maximum rather than a recommendation.

Check monthly with a gauge you own, and check cold, meaning before the car has been driven far enough to warm the tires. Ambient temperature moves pressure noticeably, so the reading you set in summer is not the reading you will have in January, which is one of several reasons our teardown on EV range in cold weather puts pressure on the winter checklist. Treat the car’s own monitoring system as a safety backstop for a puncture, not as a maintenance tool, because it typically only warns once a tire is already meaningfully low.

Reading tread depth and knowing when to replace

Tires carry moulded wear bars set into the grooves, and when the tread has worn level with them the tire has reached the minimum the manufacturer built in. Most places also set a legal minimum depth. Both are floors rather than targets, and wet braking distances lengthen well before either is reached, which is why many drivers choose to replace earlier than the strict limit. The specific legal minimum and inspection standard where you live are set by regulation, so check the local rule rather than assuming a figure you read anywhere.

Depth is not the only trigger. Replace for sidewall damage or bulges, for punctures outside the repairable central portion of the tread, for repeated slow leaks, for cracking that comes with age, and for any wear pattern that indicates a mechanical fault rather than honest mileage. Age matters even on a low mileage car because rubber changes over years whether it turns or not. Measure at every rotation and write the numbers down with the odometer reading, because a falling trend across three visits tells you when the next set is due.

Replacing two or four, and why electric cars push toward four

Mixing tread depths across an axle changes how the car behaves, and mixing them front to rear changes it more. Different depths mean different rolling radii and different grip levels, and on a car whose stability and traction systems are calibrated around consistent behaviour, that is not a neutral choice. Some all wheel drive systems are particularly sensitive to differences in rolling radius, and manufacturers of such vehicles frequently specify replacing all four together or matching within a tight tolerance.

That specification is a budget fact as much as a technical one. If your car requires four at a time, a single unrepairable puncture at low mileage can mean buying a full set, which is a strong argument for keeping rotations current so the four wear together and reach the end together. It is also an argument for taking road hazard protection seriously if it is offered on reasonable terms. Check what your own vehicle specifies before you assume you can replace a single tire, because assuming wrong here is expensive in a way that shows up later as drivetrain wear.

Choosing a replacement: staying with the factory fitment or moving

At replacement time you face a real decision rather than a formality. Staying with the original specification preserves the characteristics the car was tuned around, including range, cabin noise and often ride comfort, and it removes any doubt about load and speed rating. Moving to a different tire can save money, gain wet grip, gain tread life, or all three, at the cost of some range and usually some quiet. Neither answer is universally right.

The way to decide is to name your priority before you shop rather than after. If your driving is mostly steady cruising and range is tight for your routine, weight the efficiency side. If you drive in persistent wet weather, weight grip and accept the range cost. If cabin noise is what you notice most, ask specifically whether the candidate has internal damping. Whatever you choose, the load index and speed rating are fixed constraints, not part of the trade. A fitter who can see the car and the placard is the right person to confirm the shortlist.

Winter tires and the second set question

In climates with real winter, a dedicated winter tire is a grip decision rather than an efficiency one, and the mass of an electric car makes it a more consequential decision, not a less one. A heavier vehicle carries more momentum into every stop, and no amount of clever traction control creates grip that the compound cannot deliver on cold, packed surfaces. Where winters are genuinely cold, a second set on separate wheels is a common approach and it has a side benefit: each set only accumulates part of the year, so calendar life rather than tread wear often decides their replacement.

The cost picture is a swap rather than pure addition. You buy an extra set and pay for changeovers twice a year, but each set wears at roughly half the annual rate, so the per mile tire cost rises less than the sticker suggests. Storage matters too, since tires keep best somewhere cool, dry and out of sunlight. Whether the trade is worth it comes down to how many genuinely cold weeks your climate delivers and how much you value certainty in them.

The arithmetic: what tires cost per mile

Here is the model this teardown uses throughout, held consistent so every later figure ties back to it. A fitted set of four costs an illustrative $1,000 and covers 32,000 miles, which is $0.031 per mile of tread wear. Rotation every 6,000 miles at $30 adds $0.005 per mile, and an annual alignment check amortised across the year adds about $0.001. Together the tire block is about 3.7 cents per mile, which at 12,000 miles a year is roughly $447.

A gas baseline for comparison, using the same style of illustrative figures: a $700 fitted set covering 45,000 miles is about 1.6 cents per mile, and rotation on a slightly longer interval plus alignment brings the block to about 2.1 cents, or roughly $247 a year at the same mileage. The gap is about 1.6 cents a mile, which is $200 a year at 12,000 miles. That is the honest size of the tire penalty in this model, and it is real money without being anywhere near large enough to overturn the energy saving that our cost per mile teardown describes.

How set life varies with vehicle and driving

The single figure that moves the arithmetic most is not the price of the set, it is how long it lasts, and that varies more than anything else in the model. Vehicle mass, whether the fitment prioritises efficiency or grip, road surface quality, climate and above all driving style all feed into it. The chart below plots illustrative set lives against a gas sedan baseline so the relative sizes are visible. Every bar is a placeholder chosen to show shape, not a measured result for any product or vehicle.

The spread in that chart is the real finding. Vehicle choice moves the number, tire choice moves it, but the biggest single swing in the illustration comes from habits rather than hardware. That is unusual among running costs, most of which are set the day you sign the paperwork, and it means the tire line is one of the few places where changing your own behaviour changes the bill directly rather than marginally.

Where tires sit in the total cost per mile

Now fold the tire block into the wider running figure, because the share is what makes this topic worth an article of its own. Using home charging at an illustrative $0.15 per kilowatt hour and a consumption of 0.30 kilowatt hours per mile, energy costs about 4.5 cents a mile, or $540 in a 12,000 mile year. The tire block from the arithmetic above is 3.7 cents, or $447. Other routine maintenance, meaning brake fluid, coolant service, cabin filters, wipers and the 12 volt battery all amortised across their intervals, comes to about 1.8 cents, or $216.

Together that is $1,203 a year, or right about 10 cents a mile, and tires plus rotation are close to 37 percent of it. That share is the thing to carry away. On a gas car at illustrative fuel prices the equivalent tire share would sit near a seventh of running cost, buried behind fuel. On an electric car, tires are the second largest running line after energy and are within striking distance of it. Run your own tire price, set life and electricity rate through our cost calculator to see where your split falls.

A worked example: 100,000 miles of tire spend

Push the model out to a full ownership span so the numbers stop being abstract. At an illustrative 32,000 miles per set, covering 100,000 miles needs a little over three sets, which at $1,000 fitted is about $3,125 of tread. Rotation every 6,000 miles gives roughly 16 or 17 visits at $30, so about $500, and alignment checks across those years add roughly $100. The tire total for 100,000 miles is therefore about $3,725, call it $3,700.

Run the gas baseline the same way. At 45,000 miles per set, 100,000 miles needs about two and a quarter sets at $700, so roughly $1,556 of tread, plus about $400 of rotations and $100 of alignment, for a little over $2,050. The gap across 100,000 miles is about $1,600. That is a genuine number worth putting in the purchase decision, and it is also comfortably smaller than the fuel saving over the same distance in our electric versus gas cost teardown. Both things are true at once, which is why the honest framing is a reshaped budget rather than a hidden cost.

How driving style changes the number

Take the same car and the same tires and change only the driver. Using the chart above, moving from the 32,000 mile factory fitment case to the 18,000 mile hard-driving case takes tread cost from 3.1 cents a mile to 5.6, which on 12,000 miles a year is a swing from $375 to $667. Nothing about the car changed. No option was chosen differently. The entire difference is how often the accelerator went to the floor and whether rotations happened.

The habits that protect a set are unremarkable and mostly free. Roll onto the accelerator rather than stabbing it, especially in wet or cold conditions when grip is lowest. Lift early and let regeneration slow you gradually rather than lifting abruptly at the last moment. Take corners at speeds that do not require the tread to work at its limit. Keep pressures correct. Rotate on schedule. Those same habits also extend range, which is why our teardown on maximising EV range and this one end up recommending broadly the same driving.

Common mistakes that cost a set early

The failure patterns repeat. Skipping rotations because the car never asks for service is the most common, and it is how half a set of usable tread ends up in a skip. Ignoring a pull or an off-centre steering wheel for months, which quietly scrubs an edge away. Trusting the dashboard pressure warning as a maintenance prompt rather than as an emergency alert. Replacing tires without diagnosing why the old ones wore unevenly, which guarantees the new ones repeat the pattern.

Two more are specific to electric cars. Buying purely on price and dropping below the specified load index, which is a safety decision disguised as a saving. And assuming that because the brakes never need doing, nothing under the car needs doing, which is exactly the mindset our maintenance schedule teardown exists to correct. Suspension components on a heavy car also work harder, and a worn bush or damper shows up as uneven tire wear long before it shows up as a noise, so unexplained wear deserves an inspection rather than just a new set.

Warranties, road hazard cover and what they do not do

Tire warranties are a source of misunderstanding because they cover less than people assume. A manufacturing defect warranty covers faults in how the tire was made, which is rare and usually shows early. Some products are sold with a mileage expectation attached, and where that exists it is typically prorated, meaning a claim reduces the price of a replacement in proportion to the tread you did not get rather than refunding you. Conditions almost always include documented rotations at specified intervals, which is another reason to keep the paperwork.

Road hazard protection is a separate product covering damage from punctures, impacts and debris, sold either by the retailer or bundled with the tires. On an electric car it can be worth more than average, both because sets are expensive and because vehicles that require matched replacement across an axle turn one bad puncture into a large bill. Read what is excluded, how long cover runs, and whether it pays for replacement or only repair. Do not assume any of it is included, and do not assume a claim will be simple without service records.

When the cheaper tire is the more expensive one

Price per tire is the most misleading number in this entire subject, because the thing you actually buy is miles of tread with a given level of grip. A set at $700 that covers 20,000 miles costs 3.5 cents a mile of tread. A set at $1,000 that covers 32,000 miles costs 3.1 cents. The more expensive set is the cheaper one, and no amount of staring at the shelf price reveals that. The only comparison that means anything is cost divided by expected life, and it needs an honest estimate of life for your car and your driving.

Grip complicates it further, and in the right direction. A tire that stops shorter in the wet has a value that never appears on the invoice at all, and it is not a value you should trade away for a few tenths of a cent per mile. The sensible order of operations is to fix the safety requirements first, meaning size, load index, speed rating and wet performance you are comfortable with, then compare the remaining candidates on cost per mile rather than on sticker price.

Building tires into your ownership budget

The reason tire spend surprises people is a mismatch of rhythm. Energy is paid monthly in small amounts, so it feels like the running cost. Tires are paid every few years in a single four figure invoice, so they feel like an event. Budgeting fixes the mismatch by converting the event back into a rate. Take your expected fitted set price, divide by the miles you realistically expect from a set, and treat the result as a per mile cost you are accruing whether or not an invoice exists this month.

Set aside that amount, or at least track it, and the replacement stops being a shock. Two other habits help. Record tread depth and odometer at every rotation so you can forecast the replacement date rather than discover it, and get a quote for your exact size once a year so the number in your budget is current. Our teardown on electric car monthly cost sets out how the other recurring lines fit around it, and tires belong in that picture rather than outside it.

What this changes about the buying decision

Nothing here argues against buying an electric car, and the arithmetic above says so explicitly: an illustrative $200 a year of extra tire spend sits against a much larger energy saving. What it should change is which questions you ask before signing. Ask what tire size the vehicle uses and get a real quote for a fitted set, because a large wheel diameter on a heavy vehicle can be a genuinely expensive combination. Ask whether the factory tire has a foam liner. Ask what the specified rotation interval is and whether the fitment allows a normal rotation pattern.

Those questions take ten minutes and they turn the largest consumable on the car from an unknown into a line in the spreadsheet. It is the same reasoning our teardown on whether electric cars are cheaper to maintain applies to the rest of the service list: the savings are real, and they stay real when you account for what actually remains rather than assuming the whole category disappeared.

The bottom line

Electric cars wear tires faster for two reasons that are not going away: they weigh more, and they deliver full torque instantly. That combination shortens set life and, because heavy vehicles often need higher load ratings and larger fitments, tends to raise the price of a replacement set at the same time. In this teardown’s illustrative model that lands at about 3.7 cents a mile against roughly 2.1 on a gas baseline, close to 37 percent of a 10 cent per mile running figure, and about $1,600 more across 100,000 miles.

The response is unglamorous and effective. Rotate on the interval your manufacturer specifies, keep pressures at the placard figure, check alignment yearly and after any hard impact, respect the load index and speed rating absolutely, and compare replacements on cost per mile rather than sticker price. Then use a smooth right foot, which is the only lever in this entire teardown that costs nothing and moves the number most. Do that and tires stay a planned line in the budget rather than the invoice that undoes a year of cheap charging.

AmpLoft publishes this as independent educational writing about how tires behave and get priced on electric vehicles, not as a fitment recommendation, a safety inspection, or a substitute for a qualified tire professional looking at your actual car. No tire brand, model, compound or tread-life warranty is named or endorsed anywhere above, and no manufacturer test data is reported. The $1,000 fitted set, 32,000 mile set life, $30 rotation, $700 and 45,000 mile gas baseline, $0.15 per kilowatt hour rate, 0.30 kilowatt hours per mile consumption and the resulting 3.7 cent and 10 cent per mile figures are internally consistent placeholders for this article alone, chosen so the arithmetic can be followed, and they are not quotes, survey results or market averages. Set life in particular varies enormously with vehicle, tire, road surface, climate and driving style. Load index, speed rating, tire size and inflation pressure requirements come from your vehicle’s door jamb placard and owner’s manual, which govern over anything written here, and legal minimum tread depth is set by regulation where you live. Tires are safety-critical: have replacement, repair and inspection decisions made by a qualified fitter.
