I bought some 15x8 cragars for my car and the backspace in the front was 4.25 and the rear was 2.5 and the tires were 235/60/15 and had trouble with the rear rubbing but with air shocks it was fine. But decided i want taller tires and deep dish all the way around so sold the wheels and tires and the cragars im getting now are 15x7 backspace is 2.25 im hopeing to run taller tire so does any one have 15s on a car with 70s not 60s tires if so could you let me know how wide of a tire will work with out rubbing thanks. Or if the 275 60 will fit
