Your current tires are just bigger than the overall stock diameter. If your looking for new tires, you cant go wrong with 225-245/45/18 or 245/40/18 tire size. They will match your stock diameter better. I would go all same size tires as previous mentioned.PhEnoM78 wrote:ok i was told i have the wrong tire size on my g35 rims for my coupe.
