I went to get new tires on my truck last month. 3 of the 5 bays at the tire shop had teslas getting new shoes. I asked the shop owner and he said EVs eat tires. Like 9-12 months max lifespan, great for business. I couldn't believe it but I've always heard there's exponential wear on tires relative to weight.

This doesn't make sense. A Tesla weighs about as much as an SUV. We don't hear about SUVs eating tires. If Teslas specifically are in the tire shop more, perhaps it's that Teslas ship with shitty tires. I've heard of a number of car makes that ship with really fragile OEM tires as a way to get you back into the shop for service.

EVs can accelerate much faster than an SUV. I imagine that could explain part of the difference.

It's a combination of the weight of the vehicle and the torque that the electric motors produce.

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.

EV 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.

Our bz4x has 16,000 miles and the tires are like new. And it’s 400 pounds heavier than a Model 3.

Slow speed turning wears tires hard and unevenly. Like geologic erosion, such wear can promote and accelerate more cutting.

depends on the car, model 3 weighs the same as a M3

That makes more sense, but if that's true, you can avoid the extra tire wear by driving like a granny (which reportedly works, according to one of the other comments here).

No, 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...

It's only common because Tesla is popular. Other brands put reasonable tires on.

Anecdotally, 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.

This 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.
