I was at Sears today to see if they had any 18" rims with the 5x108 pattern. They had a couple they could order but said that they could not install or warranty them or the tires because there FWD rims on a RWD car. This didnt make any sense to me? It would seem there would be no difference. Was this guy just a douche and have no idea what hes talking about or am I wrong in thinking theres no difference?
