for my front valance i just turned the tire till it was close, traced around what i thought it would need, then took some tin snips and hacked it away. in the future i plan to pull the valance off and clean up the cuts a little. as for the back im not sure, depends on where its hitting(inside,middle,outside)

The front valance is easy. The back, I don't know. Just take your time and cut a little at a time. Remember, once you cut it off, it's gone. Just trim a little at the time untill you have enough clearance.
