My girlfriend has got a 2002 Mitsubishi Mirage. It has 4 lugs on the tire, but when I am looking at rims i rarly see just 4 lug i see like 4x114.3 or something along those lines. I do not know what this means. I think I need to know the diameter of her wheels. I do not know anything about doing this sort of thing, can anyone help me?
