An an EV owner, I can testify that the tyre wear more than makes up for the reduction in brake dust. I’ve had to change tyres every 10K miles.
- bryanlarsen 1y agoWe went 70,000 km on our first set.
- tjkrusinski 1y agoAre you constantly accelerating quickly? Haven't had this experience.
- thatwasunusual 1y agoFrom the article: > "Even when summing up emissions from tires, brakes, and road wear, BEVs produce 38% less particulate pollution than gas-powered cars before even considering their lack of tailpipe emissions."
- jayd16 1y agoPresumably this is a joke. Mine lasted 5 years, 50k miles.
- jader201 1y agoNo, it’s not a joke. EVs are heavier vehicles, and it’s common for EV owners to have to change tires much more frequently. https://www.cars.com/articles/do-evs-wear-through-tires-more-quickly-than-gasoline-cars-481973/ https://www.cars.com/articles/do-evs-wear-through-tires-more...
- jeffbee 1y agoIt's only common because Tesla is popular. Other brands put reasonable tires on.
- jader201 1y agoAnecdotally, I own a Kia EV6, and had to get new tires within two years, under 20k miles. I leave it in eco mode, so acceleration is nerfed, too. We’ll see how long the new set of Michelin Defenders last.
- jeffbee 1y agoSome models of the EV6 come with Pilot Sport 4S tires which is absurd.
- YZF 1y agoI have a model 3 and still running my original set of summer and set of winter tires. 6+ years. I just don't put pedal to metal every time I accelerate.
- loeg 1y agoThe tires that came on my Kia EV9 are bad in several dimensions (Kumho Crugen HP71) -- poor longevity, poor winter performance. People seem to get 15-20,000 miles out of them. (I replaced them with CrossClimate2s.)
- JKCalhoun 1y agoI assumed instead they were soft compound tires with a low treadwear number. Nice for "sport" driving but they wear very quickly.
- KennyBlanken 1y agoAll the people claiming EVs wear tires faster probably don't have the slightest idea that tires even have treadwear ratings. That coupled with the total uselessness of personal anecdotes... Performance oriented EVs, just like performance oriented ICE cars, are going to have softer, stickier tires that wear faster.
- loeg 1y ago> Performance oriented EVs, just like performance oriented ICE cars, are going to have softer, stickier tires that wear faster. brtkwr has a Kia Niro, not a Taycan. It's not a performance vehicle. That said, I agree he's likely got tires with shit longevity.
- rapsey 1y agoDo you accelerate with full power every time or something?
- ghushn3 1y agoWhat are you doing to your tires that they only last 10k miles? I think that might be a driver error issue, because my EV (a heavier sedan) basically never needed tire replacement barring me running over a screw or something.
- brtkwr 1y agoJust normal driving, it wasn’t quite so bad on our previous car which was a Nissan Leaf (with 30kWh battery) but our current Kia Niro just has a lot bigger batter (64kWh) and it is a lot heavier I suppose, the tyres just don’t seem to last as long. I’m pretty sure I’m using summer tyres all year round (I live in the UK) this was recommended by the dealer
- HPsquared 1y agoSome tyre compounds wear a lot faster than others (though often with better grip). I wonder if that's contributing. The other thing is poor alignment (especially toe settings) which cause the tyres to fight each other constantly. It can be a very small difference, almost imperceptible but still accelerate the wear. 10k miles is very short for a tyre. Often you can tell a lot from the tyre temperature after a drive: if they're getting very warm, it can indicate problems, e.g. if one axle has much warmer tyres than the other (hard to give an objective standard on that, though, so many factors)
- thedougd 1y agoAren’t higher speed rated tires softer? Maybe try swapping for a lower speed rating unless they plan on driving it at extreme speeds.

- relaxing 1y agoEV owners aren’t exactly rare around these parts. Neither are people who drive cars of a similar weight, such as midsize SUVs. There’s no good reason why you should be changing your tires at 10k miles.
- madaxe_again 1y agoWhen you can see interleave that’s a good reason to change your tyres. My stock tyres on a model Y lasted 11,000km - but my daily drive is a tortured ribbon of tarmac with nothing but corners.
- relaxing 1y agoI don’t know what interleave means in your country but the way to measure tire wear is replace when tread depth gets below 1.6 mm. Next time get tires with a 50k mile warranty, like Pirelli Scorpions.
- madaxe_again 1y agoInterleave is the woven metal below the rubber.
- barbazoo 1y agoThis is not at all my experience after 2.5 years and 20,000km. It’s kinda obvious that it’s completely up to the driver.
- altairprime 1y agoRivian?
- xeonmc 1y agoIf you're on a Tesla, it might be because of incorrectly set cambers out of the factory: https://www.youtube.com/watch?v=O1kdxm5cKfA https://www.youtube.com/watch?v=O1kdxm5cKfA
- i80and 1y agoThere is something seriously wrong with your tires if that's actually the case. I drive a pretty heavy EV myself (an AWD ID.4) and your wear is ludicrous.
- irjustin 1y agoHow is tire wear related to the method of power? It could be a steam engine for all it mattered. Accelerating and decelerating, in regards to the tire, don't care what is causing the force.
- dgemm 1y agoIt's related to vehicle weight, electric cars can be significantly heavier.
- ddispaltro 1y agoMy understanding is a model X is 20% heavier than a similar size mid-range suv like a telluride, which I would consider the same size SUV. The Model X's curb weight ranges from 5,148 lbs to 5,531 lbs, while the Telluride's curb weight falls between 4,112 lbs and 4,482 lbs.
- loeg 1y agoModel X is somewhat smaller than a Telluride, but close enough.
- ccc3 1y agoMass. Electric cars are much heavier. F=ma.
- jaggederest 1y agoFor tire degradation I believe it's actually something like the 4th power of the mass, same as for roads.
- potato3732842 1y agoThe tire isn't constant like a road is though. Tires intended for bigger heavier vehicles get harder rubbers.
- deleted 1y ago
- neilwilson 1y agoThat’s very likely due to the tyres having less tread depth - a common trick with EV tyres to reduce rolling resistance. Michelins are the main culprit. Of course the tyre companies love that little trick as they can pretend they are being green while selling more tyres. Always check how much tyre you’re buying
- breakyerself 1y agoI have a 2019 model 3. 200,000 miles. I'm about on my 3rd set of tires.
- linotype 1y agoAre you racing? I haven’t had to change our tires on our EV for 30k miles (we just hit that on the odometer; these are dealer tires).
- lokar 1y agoThere are three things at play here: - evs have a reputation for fast acceleration, and many drivers use it. More wear. - evs are heavy due to large batteries trying to match ICE range. More wear. - evs often come with low friction tires to improve range, they wear faster The second two issues should gradually go away as battery (and charging) tech improves.
- idiotsecant 1y agoLow friction tires wear slower, not faster, on account of being ... Low friction. Friction is what wears tires.
- pengaru 1y ago> Low friction tires wear slower, not faster, on account of being ... Low friction. Friction is what wears tires. They're not low friction tires, they're low rolling resistance tires. Friction relates to the grip, rolling resistance relates to the heat generated by the deformation of the tire. A less compliant, often narrower tire may wear faster than a more compliant wider one. It depends. "Tyres account for about a fifth of the energy required to power a car. They provide friction, so that the vehicle can grip the road, but some of the power supplied to the tyres is then lost as heat. Indeed, Michelin, a French tyremaker, estimates that this “rolling resistance” accounts for 4% of the world's carbon-dioxide emissions. Tyre designers have therefore sought to improve fuel economy by reducing rolling resistance. However, this not only reduces a tyre's ability to grip, making drivers take corners sideways, it also wears out the tyres more rapidly." from: https://www.economist.com/technology-quarterly/2009/12/02/rolling-out-the-changes https://www.economist.com/technology-quarterly/2009/12/02/ro... without login: https://archive.is/TiIUk https://archive.is/TiIUk
- potato3732842 1y ago>They're not low friction tires, they're low rolling resistance tires. Those two attributes are pretty decently tied together, can't get one attribute maxed out without a solid showing of the other.
- webprofusion 1y agoMine did more than 25,000, just get better tyres. The basic premise is that EVs are heavier and have more torque than average cars, but it's a 20% difference in real life, so your tyres may last 20% less.
- graemep 1y agoIs it a linear relationship? I know road damage is far higher (fourth power of weight) so maybe wear on tires is also worse than linear? heavier vehicles are also worse in many other ways (e.g. less safe for pedestrians, require more space for parking,...) and we really should be encouraging smaller vehicles.
- dyauspitr 1y agoDon’t accelerate like a maniac.
- jillesvangurp 1y agoSwitch tire brand and type or get some advice. Whatever you are currently getting isn't the right tire for your car, obviously. You should be seeing much longer lives for your tires. Even with an EV. So, something is off. And tires of course aren't created equally. There are many different types of tires and they are optimized for different circumstances. If you mismatch your tires to e.g. weather conditions, you are going to have issues. Not just with EVs, but with any car.
- sjducb 1y agoAgreed parent needs to get advice from 2/3 different tyre shops. Changing tyres every 10k means something is wrong.
- infecto 1y agoThat or just slow down. I swear 90% of the people that complain of tire wear drive oblivious and are flooring it after every stop. Even a Kia Beri which what the parent has, has more kick than a ICE.
- sjducb 1y agoMaybe, I think the tyre shop is encouraging premature tyre changes. My local tyre shop recommends changing the tyres at 3.9mm. The tyre’s data sheet says it’s ok down to 1.6mm. You’re wasting 2.3mm of tyre, which is 30% of the life of the tyre.
- snowe2010 1y agoThat’s not normal. You’re either doing something incredibly wrong or you’re changing your tires when you don’t need to.
- thanhhaimai 1y agoI'm not sure I can agree with this. I have 2 EVs, and the tire looks almost brand new after like 10k miles. I think the driving habits matter more than whether the car is EV or not.
- loeg 1y agoIt's probably the specific tire being awful, or alignment.
- yreg 1y agoI have 42k km / 26k miles on the tires Tesla equipped me with and they are in good condition.
- mpyne 1y agoI own one EV, at 40k miles, and have had to change the tires only once so far, and even that was more because of damage to one that required replacement than due to excessive tire wear. I can vouch for the very low brake pad usage as well.
- reissbaker 1y agoThe article says that even including tire and road wear, EVs generate 38% less particulate pollution than ICE cars before considering the lack of tailpipe emissions.
- labster 1y agoBut tires are black, and black carbon has additional climate effects — even once the aerosol lands, it can still have effects like black carbon on snow.
- ZeroGravitas 1y agoOn that topic, Norwegians have been reporting that the piles of snow at the sides of their roads are noticeable cleaner since EV adoption took off.
- mort96 1y agoIt's not like brake dust is white...
- infecto 1y agoGuess what comes out of petrol and diesel exhaust? Guess what color brake dust is. I guarantee the EV is going to be a lot cleaner.
- onlyrealcuzzo 1y agoWonder what that ratio will be when battery tech advances enough that BEVs weigh the same as, and eventually less than, ICE cars.
- djrj477dhsnv 1y ago> An an EV owner, I can testify that the tyre wear more than makes up for the reduction in brake dust How could you possibly measure that just from your personal experience? Sounds more like a wild guess that is in contradiction with actual studies.
- potato3732842 1y ago>How could you possibly measure that just from your personal experience? Simple napkin math by comparing longevity of parts with volume of parts consumed.
- p_j_w 1y agoSure, but your personal experience could very easily be on the higher end of the distribution. You simply CANT confirm something like that based on personal experience. Either your personal experience lines up with some statistical fact or it doesn’t, either way, without the proper statistical context it’s borderline useless.
- potato3732842 1y agoSure, but if the napkin math spits out results orders of magnitude higher than reasonable personal variance then you're still on the way to a decent answer. FWIW I think the qualitative difference between tire and brake dust is going to mean a lot more than individual variance.
- 01100011 1y agoI wonder if you got unlucky with tires. Seems some mfgs are playing with new recipes and eco friendly ingredients causing the tires to dramatically miss their stated lifetime. My last tires were Michelin Defender somethings from Costco and they lasted about half the expected mileage even with regular rotation and proper inflation.
- cbeach 1y agoI think there might be something peculiar about the driving or environment. I have put 50,000 miles on my EV over the course of a few years and only changed the tires twice in that time. The car is MOT-tested every year so I have precise measurements of tread.
- originalvichy 1y agoYou are an anomaly. The overwhelming majority of EV drivers say their tyres last very long.
- bluedino 1y agoI was just reading an article where an electric car had the original brakes on it for 250k miles
- infecto 1y agoI am firmly in the camp that problems like these have less to do with being an EV and more to do with one of the following: 1) Aggressive driving which is easier to do in a number of EVs due to instant torque. 2) tire compound, a lot of oem tires are soft 3) something wrong with the cars drivetrain or suspension. 10k is comically low, my model y oem tires lasted to 30k before tread depth passed the safety threshold. I also keep it in chill mode.
