Tires barely have anything to do with curb rash protection. Plenty of Accords, Camrys, Civics, Altimas out there with curbed wheels and fat tires on them. Go walk down a busy city street and look at all the parked cars. Curb rash is the norm, there are less cars with perfect wheels than curbed wheels, I can guarantee you that.
Curb rash is caused by the driver, not the wheel or tire.
