I have just mounted my rear fenders and they are rubbing my tires. I did't take into account for the buldge in the sidewall of my tires. I need to figure out the easiest and most affordable way to move in about an inch. I would like to keep my 8" inch wheels, all four are the same, so I can rotate them periodically. Will changing tires give me the space that I am looking for?? Or do I nee to change rearend overall width?? Or will changing brakes from drum to disc give me any extra room?? Please help!! Any info in reguards to these questions would be greatly appreciated.
