I have 15" cragar SS wheels on my 86 camaro with the stock rear end. The rear tires arent holding air, but the fronts are great. Im thinking about buying the same tires as the front, but a little wider. The tires are really skinny on there now. Does anyone know what the widest tire i can fit on these wheels?

 

You failed to tell us the current tire sizes, and the wheel width. Simply claiming 15" Cragar SS isn't enough, they were offered in several widths.
