I need to order my wheels very soon but don't know correct specs for challenger bolt pattern. I'm going to run a 15x7 wheel. But I need to know what backspacing is correct. Bolt pattern is 5x4.5"(thanks NZ!) I am going to run a BFgoodrich radial T/A. Was thinking about a 235/65 R15 anyone have an suggestions or pics of sizes of BFG's on their cars?
