I just bought a set of aftermarket wheels and tires for my 05 electrglide. I have a 21"x 3 1/4 on front and 18 x 4 1/2 on rear, the rear tire is a 150 both front and rear are close the rear is maybe 1/4" from fender lip on the pulley side and the front has maybe 1/2" from center of tire to the center of fender. I did drill out the back mounting bolts of the front fender and rotated. Anybody know anything about this? I also want to lower the rear which I think will be okay, it appears there is room in rear, how much tire grow or travel do I need to figure for.
