i put a 21 on a buddys 2012 street glide and it is rubbing the fender and causing caos. I took it back off drilled the rear holes out with a 3/8 drill bit and rocked it up and i still dont have the clearance i need. I also put aftermarket chrome lowers on it.. maybe the mounting points are off from factory. I have put a bunch of 21s on and never had one rub. Also the tire is a 120/70. just wondering if any of you guys have seen this and what did you do to correct it? does someone make a fender or adapters? This guy is really picky too!! I feel like an idiot because i have put 26s and 23s on without a problem..and this 21 is whooping my ass.lol.thanks guys!
