Only 7k Miles? EV Owners Not Happy About Tires Not Lasting Long
- kwertyoowiyop 3y agoLove the “anecdata” from someone who has only done 3 EV tire changes in a year.
- I_Am_Nous 3y agoI ride a 750 pound motorcycle. It has similar issues with chewing through tires unless you get a super long life, hard compound tire, which has its drawbacks on grip for cornering and braking. However I cannot lie to myself or anyone about how heavy it is. If it lays down, I have to pick up 750 pounds worth of bike. No such option with EVs though. If your vehicle is nearly a ton heavier than a similarly sized ICE vehicles, you may never think about how that weight affects things and then comes the surprise that it affects all kinds of things. EVs are cool. They are not a 1:1 replacement for ICE yet.
- TheChaplain 3y agoWhat kind of bike is that? A Softail is ~630 and that is huge imho
- mschuster91 3y agoI wouldn't be surprised if they drive something like a Honda Goldwing - the undisputed Big Chungus of the motorcycle world, clocking in at up to 800 pounds [1]. [1] https://de.wikipedia.org/wiki/Honda_Gold_Wing https://de.wikipedia.org/wiki/Honda_Gold_Wing
- I_Am_Nous 3y agoYou called it pretty close, it's a Goldwing competitor, the Kawasaki Voyager XII - 1200cc inline 4 cylinder. Half the engine that's in my Jeep Renegade lmao
- I_Am_Nous 3y agoKawasaki Voyager XII, as someone commented to you it's a Goldwing sized touring bike with an inline 4 cylinder 1200cc engine. It shares a lot of blood with the Ninja so it's quite a fun bike even for its size, very maneuverable.
- vr46 3y agoI had to convert that but yes, that is a very heavy bike. I have a 1200RT and yours is 100 kg heavier, goodness knows on what. I know that the Michelin Road 6 comes in GT versions with an extra ply for heavier bikes - maybe that's actually for yours and not mine!
- I_Am_Nous 3y agoMost people ride Michelin Commanders on these bikes (Kawasaki Voyager XII) but even the stock tires had sidewalls which cause low speed wobbles and unexpected handlebar locking right as you start to put your foot down. The front tire just doesn't have enough strength for the weight of the bike lol
- vr46 3y agoThat’s pretty nuts, I thought those were cruiser tyres specifically with softer sidewalls, whereas sports tourer tyres have those stiff sidewalls for better handling. I think all the K1600s I’ve seen, similar weight, had Metzler Roadtecs or Z8s on (great tyre BTW, always rated a Metzler front tyre, even if they wore out quicker than the Michelin, lovely while they last). Still, sounds like an interesting characteristic to get used to. Always wanted a go on a really massive cruiser/tourer, but I struggled with my tutor/observer’s Pan European, made me realize that the RT’s design was a lot cleverer than I thought.

- bryanlarsen 3y agoEV's are nowhere close to "nearly a ton heavier". The Ford Lightning with the long range battery are about 1,000 pounds heavier than a gasoline F-150 SuperCrew. A Telsa Model 3 is about 400 pounds heavier than a BMW 3.
- I_Am_Nous 3y agoObviously there's variance between models but comparing the Hummer EV to the H3 it's nearly double the weight, nearly two tons heavier.
- asadotzler 3y agoHummer EV isn't really a representative EV though, is it? There are less than 3,000 EV Hummers on the road, compared to, for example, almost a million Tesla Model 3s. The Model 3 battery is about 1,000 lbs.
- meheleventyone 3y agoSo much WTF in this article, like the regenerative braking thing as if the torque for both regular braking and regenerative braking doesn't have to be put through the tyres to slow things down. I definitely buy people with EVs hooning it around the place wrecking their tyres. It is really easy and fun to make use of all that torque. But it's not actually required.
- simfree 3y agoIt's Wyoming, the drivers who have EVs are probably burning up quite a bit of rubber with harsh accelerations and decelerations unlike the median driver elsewhere. Only 800 people in the state even own an EV. As one of the select few EV owners you can easily accelerate past the vast majority of the other cars on the road in Wyoming.
- LinuxBender 3y agoThere's about to be a few more as UPS and FedEx are getting EV's here in Wyoming soon. I am looking forward to hearing their experiences in EV delivery trucks.
- I_Am_Nous 3y ago>He also speculated that “regenerative breaking,” where tires work really hard to stop due to torque stress instead of friction braking in gas-powered cars, as another possible wearing effect on tires. A visual is a “twisting effect” of what happens with a dragster’s tires when a driver peels out, he said. Those tires have a shelf-life of roughly a mile-and-a-half when the soft, burning rubber vulcanizes and cracks. I'm not sure I follow what you mean when you say regenerative braking doesn't have to be put through the tires. The only reason you can do regenerative braking is because the vehicle inertia wants to keep going forward, so you allow that rotation to be used to drive the rotor and generate electricity. The ground resisting that rotation is required for the motor to have a generative load put on it. Either way it's still more you are asking the tire to withstand.

- bryanlarsen 3y agoWe've got 61,000 km on our Model Y. A small majority of the mileage is on the original tires, and the rest on our winter tires. Lots of tread left on both sets. Want your tires to last? Don't drive like a moron.
- simfree 3y agoGotta get past all the ICE drivers on the road in Wyoming with your extra torque :D Nevermind how that burns rubber like crazy...
- justinator 3y agoI was driving with a dude in his Rivian and he talked about burning through tires. "Look: I like to go FAST".
- bryanlarsen 3y agoI do know a couple of Tesla owners who had to replace their tires at 10,000 km. (7,000 miles). They learned their lesson and their second set is lasting a lot longer.
- foogazi 3y agoWhat’s the lesson ?
- etrautmann 3y agoDon’t test the acceleration every time you drive from a stop sign
- deleted 3y ago[deleted]
- nik282000 3y agoTires last longer when you treat the controls as analog not digital. This is a problem for all terrible drivers, it turns out that a disproportionate number of assholes are also rich enough to buy electric.
- graemep 3y agoNot just rich enough - the kind of person why has to have the latest and greatest. Very often insecure. You know exactly the sort of ICE car they would buy too.
- iwanttocomment 3y agoHave an older EV as well as a PHEV that is mostly driven electric except for occasional road trips. 10+ years on both. Had to replace the terrible factory tires on the EV at 20k, a disappointment. Second pair lasted ~40k. Third pair is over 25k and doing fine. Tires on the PHEV made it to 35k. Replaced them, they're still doing fine at 60k. 7k? Naah, man. Total garbage nonsense.
- Schnitz 3y agoShouldn’t tire life be very similar assuming you accelerate and brake equally hard like in an ICE car? A Model 3 doesn’t weigh that much more than a Camry…
- londons_explore 3y agoTyre damage is almost entirely caused by tyres slipping. EV's could easily have a 'make tyres last longer' mode which prevented tyres slipping entirely by reducing power in all situations where the tyres are likely to slip. The car has accelerometers in, and knows fairly precisely the downforce on every wheel, and has a reasonably good guess at the road surface, so should be able to make a pretty good guess at what point tyre slippage is likely to happen, and can then keep torque slightly below that the vast majority of the time. As a bonus, if you can do this perfectly, you actually get more acceleration, since the coefficient of static friction is higher than the coefficient of dynamic friction for nearly all surfaces.
- huijzer 3y agoAh so traction control plus surface grip estimation via cameras? Current traction control is already pretty good though.
- londons_explore 3y agoWell clearly not good enough if people are managing to wear out their tyres... I suspect if you put a high speed camera on a tyre while someone was driving aggressively, you'd see many inches of sliding with every accelerate/brake.
- erik_seaberg 3y agoDoes traction control do anything if all of your drive wheels are slipping equally? Can it even tell?
- SkyPuncher 3y agoYou don’t need that, you just need to limit the initial torque. That’s what eating up this tires. Jumping well past initial grip, then having traction control kick in after the fact.

- MilStdJunkie 3y agoAccelerating a five ton box to thirty meters per second in less than five seconds does tend to do that.
- averageRoyalty 3y agoWhich EV weights 5 tonnes and goes 0-100 in < 5 seconds? I'm struggling to understand.
