when i had 18x7.5 racing harts with 225/40-18 rubber on my 96 accord, the front tires would get cut up by the top of the fender. make sure your wheels are pointed straight when you go up driveways and speed bumps, as the fender will only shred your tires when theyre turned and compressed (up into the fender well).

camber kits WILL NOT help, as they push the top of your tires out, and cause you tires to rub the fenders more.
