bad plan - should find something w/ the right width to start - wheels stickin out looks plain goofy IMO - the TF has 3" from the sidewall of the tire to the outside face of the fender above it - when viewed from straight out front the tire is nearly in line w/ the center line of the lights - if you go w/ the added width you'll be slingin rocks and road crud up the side of the truck
glad you ... "haven't done it yet"
