I was about to pull the trigger on a 20x11 Rohana RFX5 Brushed Titanium wheels for the rear and I found out the offset is 48MM. That to me does not seem like it is going to work. After reading other forums here I would assume I would need 55 or 56 MM. 48MM on a 11 inch rim doesnt seem like its quite enough and with 295 tires it might actually stick out. Am I looking at this correctly?
