I'm looking for other '06 Super glide owners who have uprgraded to a 21' front wheel. I'm trying to order a set of the new PMcontrast cut Domino wheels and I'm having a hell of a time figuring out what sizes I can or should order since I want to go little bigger in both the front and the back. In this forum I've read that people have successfully swapped the stock 19' rim for a 21' rim without any modifications. I also thought I remember reading that someone here swapped the 160 tire for a 180 tire without the purchase of the wide tire kit. Can anyone here give me the exact wheel sizes I could run without any modifications? I was thinking an 18x5.5 wheel with a 180 tire would workfor the rear??? Any help or info would be greatly appreciated...
