  > EV's have 100% reduction of NOx/tailpipe VOCs, 100% reduction in soot/tailpipe particulates, 70% reduction in brake pad dust (due to regenerative braking), in exchange for 25% increase in tire wear.

I replaced the tires on my Tesla model 3 at 74,000 km and they still had tread above the indicator bars. I'm now at 140,000 km and the tires look great, the back ones look like they're only about halfway done. I might be an outlier but my previous Subaru needed tires every 50,000 to 60,000 km.

Needless to say, the brake pads have never been touched and when I saw the left front one at around 110,000 to 120,000 to patch that tire, it looked like it was just installed. The regen braking almost completely eliminated the brake pad or rotor as a wear item.

Yeah, aren’t the EV tyre’s compounded differently in some way to account for the extra weight?

If the weight on each wheel is greater I’d have assumed the tyre would need to be harder, for the same performance.

I would have assumed that would counter the otherwise additional wear, but I keep hearing EV tyre pollution is higher and yet everyone who owns one has always said they aren’t changing tyres an more than they did on their combustion cars.

Given that tires have a range of warranties from 40,000 miles to 80,000 miles ... it's possible that the tires are wearing 25% faster but the consumers aren't noticing because it's still around the normal 40k-80k mile range.

No matter the warranty - I still notice when I replace them.

And the warranty requires proof of periodic rotation. If the tires are wearing evenly, as is the likely case for a new vehicle, then rotation costs significantly more than the pro-rated rebate.
