remember, your regenerative braking comes at cost of tire life.

No, it doesn’t. The tires don’t care if it’s the car’s motor slowing things down, or some friction material grabbing a disc.

I guess they are saying that the sharper braking curve that is default on Teslas is going to cause more wear than a slower braking curve. The logic makes sense, but I have some doubt's that sharp regen breaking is more to blame for tire wear vs. Sharp manual braking and acceleration.
