My tires were rubbing when I hit dips & bumps but I didn't want to get smaller tires so I was going to have a custom body shop do it (who is part of the "A" team on Over Haulin) but the owner showed me how to do it myself. It may sound scary but as long as you take your time it won't even crack the paint. If I can do it on my BMP '99 Passat then you can do it as well. No more scraping in less than 20 minutes and for free!
I'll get some pics soon because it sounds worse than it is
First you take a wooden bat & stick it between the fender & tire. You may have to jack the car up some if you are loooooow like me. Then simply apply pressure down on the bat to put pressure on the inner fender lip & roll the bat slowly & smoothly on the tire. Thats it
