#22Looks like an astroturf campaign, with essentially the same story popping up around the country. https://news.ycombinator.com/item?id=39159783
I would not be surprised if tires wear faster on a vehicle that weighs ~40% more. Another thing to consider is road damage, which is famously proportional to the weight to the power of four. [1] [1] https://en.wikipedia.org/wiki/Fourth_power_law
Not sure how you calculate 40% but that sounds wildly off, unless you are cherry picking and comparing a Rav 4 to that wildly heavy Hummer.
Lets take a real comparison though, Model Y at the top end is 4400lbs, a Rav4 at the top end is 3600lbs. Thats a 22% increase, heavier yes but not 40%.
Edit: Here is one source to show why EVs are not tearing up the road. https://twitter.com/ajisuzu1/status/1681123111364620294?s=46
My TLDR is there is essentially a cutoff where the weight matters. Going from 3800lbs to 4400lbs is not whats causing damage, its the 60,000lb loaded semi (and I think 80k is actually the max weight cutoff.

#25I can confirm faster wear but not every 7k miles. I've worked for a tire OEM before and we've been tracking tire usage on Teslas for a while. It's due to the combination of higher loads and torque

#26I’m currently at 30K and going strong on my Tesla Y factory tires.
7k is way too low, I would believe 25-30k for speedy drivers.

#27I always had to change tyres on gas-powered cars after 30,000 km, they are completely worn by then. Currently through 13k on my Tesla and while there's some visible wear i'm sure they will last at least about 25k or maybe full 30k.
The expected lifetime of tires is 100k km, I thought.

#28Seems like ev are winning. Entrenched car lobby starts to feel the pressure.

No, EVs do not damage roads. Its not famously proportional, there is a cut off and consumer vehicles, including EVs, do not damage roadways. Large semi trucks do. Not sure how you calculate 40% but that sounds wildly off, unless you are cherry picking and comparing a Rav 4 to that wildly heavy Hummer. Lets take a real comparison though, Model Y at the top end is 4400lbs, a Rav4 at the top end is 3600lbs. Thats a 22%…
Edit: turns out my car weighs even less.
Edit2: asked Google for most common, seems Tesla Model S at around 2100 kg.

#30I'm not an EV fan, but this problem has always existed for heavy cars, of which there have been many for decades.
