I have always preferred a 15" wheel on my own ride. Even though the 17" wheels and tires are super heavy they do look good. I just bought some polished 17x8 Cobra wheels for $260 with 2 good tires Couldn't pass up a deal like that. For replacing the bald rear tires I would like to use a 275/40/17. Has anyone tried this? Will they fit right or would I be better off with a 255 or 245 size?
