Surprised by tire wear

[Jim Lewis]

Great Science Friday podcast interview with Ryan Pszczolkowski. He is the tire testing program manager at Consumer Reports. He says tires do wear a lot faster on EVs because, on average, EVs are 30% heavier than the equivalent ICE vehicle, and they put out a lot more start-up torque than the average ICE vehicle. Strangely enough, he also takes regenerative braking to task for causing extra tire wear (perhaps 1-pedal driving is tougher on tires than 2-pedal driving?).

The tire can’t tell if the source of the braking force is regen or mechanical.

And (at least in Fords) the amount of regen is the same with 1PD on or off.

IMO, the tire wear is mostly influenced by driving style. I base this on owning a Mach-E almost 3 years and seeing posts about this on the Mach-E forum. One guy with a AWD EX wore his tires out in less than 20K, while another person with the exact same car with the same OEM tires still had tread left at 40K. I have 29K and it looks like I’ll make at least 40K. Weight definitely has some impact, but can’t account for this kind of variability.
