They mention ~$200/tire as if its some big expense way out there compared to most other cars. Lots of EVs have 19" rims. 235/55R19's on my ICE cost like $230/ea. Good 215/55R17's for my old 2000 Honda Accord are $170-200.
I'll probably get ~35,000mi on the OE tires on a Mach E AWD. Lots of city driving, some amount of having a lead foot. If I had babied it a bit more I'd probably have gotten ~40,000mi. I was changing the tires on my Accord every 40,000mi or so. I was just looking at tires, and they were all ~$200-220/ea, even for EV specific tire models.
