I just got a 2001 S-type it has 20 inch wheels and 245/35/20 all the way around but it will scuff the wheel well on the rear passenger side just a little when diving from time to time.My question is is that the wrong size tire and need to be switched to a 245/30/20 on the rears or should I be looking for a suspension issue?I need to get fixed soon I see just a little damage to the inner lip on the wheel well.

Thanks..
