When I tried this car cover, I was severely disappointed .The material was flimsy and didn't protect my car at all. It also had poor fitting and kept slipping off. The only good thing about this was the attractive black color that matched my car..
Heavy Duty is supposed to be a 35" or 36" tire but I think you could put this on a larger tire. Fought hard enough. If I had to make it again I would probably order a smaller size.
