Please help? I am currently running MODA R4's on my car. 17"x7.5"s with 40mm offset. I got them from Tirerack and they do fit fine... BUT something (I assume it is the wheels) make my car steer itself. I have the original BFG's on it. When on the highway if I hit bumps or dips the steering wheels moves left and right on its own. I was wondering if the wheels could cause this because they weigh more than the stockers or if because the MODA R4 wheel sticks out past the tire... ???? Or do others have this same trouble?
