Increased tire wear comes from the weight of the car and cornering. The tires need to do significantly more work in accelerating (the centrifugal kind) a car around corners at equal speed.

EVs have instant torque from 0rpm and people use it and that's the main reason. Case in point - we have a Volkswagen e-Up, it barely weighs 1000kg, it's pretty much one of the lightest cars on the road. And yet it goes through its front tyres like nothing, and that's despite very modest power output of only 80bhp. But I do accelerate hard as it's so easy to do - so it's reflected in the tyre wear.
- flakeoil 1y agoThat should be easy to fix though with a bit of software.
- m101 1y agoI agree there are effects of increased linear acceleration, however I disagree with you because of: On many roads you accelerate and brake less often than you go around corners. These two things are equivalent on tire wear given the forces involved: 1 corner at 50kmh with 50m radius. Accelerating linearly at 0.39g (7 second 0-100kmh) to 77kmh from 0.
- gambiting 1y agoI don't think that's neccessarily a disagreement? Both things can be true - if you mostly drive on roads with fast corners, the heavier car will wear out its tyres faster. If you drive on roads with lots of start/stop traffic but not many "at speed" corners then the one that consistently accelerates harder will wear out its tyres quicker.
- m101 1y agoYes, it depends on how you drive and where, however I would note the above: 50kmh is typical of city driving and 50m isn't exactly a tight radius. 77kmh is actually quite fast, and 0.39g is actually quite high acceleration (this is flooring it in chill mode in a Tesla model y). I am trying to say that the driving circumstances where the linear forces are more important than the horizontal forces are fewer in number.
- BobaFloutist 1y agoI mean, I brake and then accelerate every time I go around corners.
- rightbyte 1y agoI wonder if the uneven torque from ICEs somehow decreases tire wear. Or if like vibrations shake sand loose in starts or something.
