re: Electric cars save gas. Don't ask how long the tires last....

Maybe it has to do with weight distribution and/or how the car is driven. I'm not knowledgeable as to why.

Data i'm seeing is that the wear is slightly elevated (~5%) over similarly weight vehicles. For example Model 3 vs 3 series or C class and obviously higher for similar vehicle class but lower weight models. That tells me we still have 5% thats not accounted for by weight. That seems to be the torque wear factor, which is the wrong way to look at it because it's actually just sidewall deterioration thats impacting the load on the tread.

We are considering getting an EV as a second car, mainly for about town usage, and this issue has come up often when doing my research. Generally, the explanations I've seen say the weight of the vehicles increase tire wear.

They're solid around town cars. I didn't think much of it when my wife wanted a Model 3. We'll save enough from fuel, oil changes and brake jobs to offset a little extra tire wear. Also, i can't be holier than thou on this, i can't get 5k miles out of a set of GTR tires.
