Check your first post those size's are a little weird? HAHA.. But I think you could run a 17x9 with like 5.5 bs. The rear if you are running stock wheel wells the I don't think you can go any bigger that 9.5 and bs not sure but I bet you can get at least the same as the front if not an inch more for a little more of a lip. But anything is possible if you modify it enough
