Are you driving fast(er than with a ICE vehicle) in corners? Since EVs have a very low center of mass, drivers tend to take corners a lot faster than they would in ICE vehicles which is very hard on the tires.

A friend got hit by this as well and since readjusting his driving style (read: not flying through corners for the fun of it) he gets more (but still not equal) miles on his EV's tires before he needs new ones.
