Hello all, I just bought a black 1995 325 ic and want to add some chrome wheels to it. It came with 16' wheels but I want to go an inch or two larger. I was told that I could go up to 18' wheels, but the ride would get stiffer. I don't really understand what that means but I don't want to give up too much of a smooth ride. So would 18's be a bad idea on a 3 series?
