I'm interested to know why doing regen instead of braking would mean you have to replace the tires more often? Seeing as the tires are the only thing in contact with the road I would have thought it wouldn't make any difference what was slowing the wheels to create more friction - brakes or the engine. Can you elaborate?
I wouldn't know for sure, but suspect the relatively higher mass of an EV puts more wear on the tires during braking and acceleration. You certainly feel when the regenerative mode kicks on in a smaller vehicle.
Someone will have to pester a physicist at some point for a better answer.
