After weeks of looking at wheels of every type I think I'm going to settle on American Wire Wheels. I know there's no problem with a 18"x3.50" with a 110 or 120/70 on the front but I'm getting conflicting answers as to weather I can run a 18"x4.25" rear rim with a 150/70-18 tire without hitting anything. Has anyone out there put a 150/70-18 on the rear of a Road Glide and were there any problems? My Glide is a 2000. I guess I'll reply to myself. Harley told me they widened the swing arm around 2005 or 2006 but I could have a problem with ny 2000 Road Glide. Unless one of you tells me differently I'll have to go with a 18"x3.50" and a 140/70-18 tire to be safe.
