i have the same size tires and mine rubbed way more WITH sapacers than without...... did you try them without spacers? if not, try it!

 

way more?? to frame or to fenders?

 

mine never rubbed the frame.... with spacers it rubbed the rear inner fender and the factory mud flap much worse with spacers.... you have to modify the rear of the fender no matter what, but not as much if you lose the spacers. i also had to zip tie the front of the inner fender a bit also.....

 

Here is what I used. I went to an industrial belting company and got some leftover belting they had kicking around. Cut it to fit and I actually riveted it on. I don't have any pics of it installed, so I will have to take some for you in the next little while.
