I didn't have to do a thing and they fit fine on my car. I do want to roll the fenders a bit so that they don't rub when I'm carving the corners though.
315 milimeters, not inches. 315 inches would be 26.25 feet wide.... 315mm tire is appox. 12.68 inches.
and on my car to make my 315s fit, my quad shocks were removed before i purchased the car, and i "massaged"
my fender lip, as well as beat in my inner fender. i haven't rubbed my tires once since i did all this.
:dunno: honestly i couldn't tell you why they fit, but i've never had rubbing issues except on the inner fender well, which i just beat to hell to make work lol
I had a problem with the brake line retaining brackets and had to bend them down a bit. Goodyear eagle F1 GS-D3 tires though. Not sure in the BFs are that wide.
