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.

Have heard the same that Teslas eat tires like crazy. But why is that where their weight is comparable to a regular minivan. Is it due to the fast acceleration. If so can tire life be extended if the user is gentle on the accelerometer from zero.

Acceleration combined with the style many EV manufacturers chose. Lots of “sporty” looks leaning on large rims with low profile tires.

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.

Almost all tire wear comes from accelerating and decelerating. Some from turning and cornering. Basically anytime you are asking them to stick to the road when the car's velocity is changing. Just coasting in a straight line does not cause any significant wear, regardless of weight. (Unless the tires are grossly under-inflated.)

EVs eat tires when people drive them like they're on a race track, which is most of the time.

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.

Presumably this is a joke. Mine lasted 5 years, 50k miles.

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.

What 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.

My last two sets of tires on a Model 3 last for 30000 miles.

Good to have more data points and evidence, but this seems extremely well established by now? Zero tailpipe emissions, drastically removed brake dust, slightly higher tire wear (due to weight), but much better overall than ICE.

I am just excited because the more EVs mean fewer idiots in hot rods running without mufflers.

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