Looks like an astroturf campaign, with essentially the same story popping up around the country.

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]

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% 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.
