Can you share them? Because physics says that damage to roads scales quadratically with weight. Not sure why tires would not experience a similar increase.

At the very least, these tires are subject to higher forces due to the heavier weights of EVs. Intuitively, consistently applying higher friction forces to an object would cause higher wear.

It’s much worse, it actually scales quartically with weight.

The weights aren’t really that much higher than ICE cars, but I don’t think anyone who has owned an EV would say they don’t go through tires faster. They do. How much due to weight, how much due to better acceleration, I don’t know, but they definitely are harder on tires.

Some factors I think are involved, but I don't see mentioned - EVs produce more readily available torque in general, and also tire choice heavily factors in EV range (low rolling resistance), which has a negative impact on tread life

EVs use different tires from the factory than regular cars to help increase efficiency, maybe it's about the type of tire?

[uxp100]

That’s a factor too. My stock tires were quite soft, though they were a tire that was also used on non EVs in Nissans lineup.

Three or four years ago, yes. Newer EV specific tires don't seem to be wearing faster.

Unfortunately Nissan did not put such a tire on my Ariya. Good range and very quiet but very soft and only 9/32 from factory means lots of people have to replace em after 15 to 20k.

I’m replacing earlier given poor snow and rain performance. They can have em back when my lease is up.

[Schiendelman]

Understood, but that's Nissan sucking.

I would imagine it's just tire formulation choices. Tractor trailers get extremely high mileage from their tires, but there is lots more weight on each tire. And train wheels... what is the load and mileage on those?
