So, if you haven't seen me on the forums since I joined let me start with: I just bought a Suzuki Boulevard M50 last week. Looking at buy my wife a 2010 Honda Shadow Phantom in the next few days, probably this Saturday. The Phantom needs a new back tire but the actual size the OEM state is limited in tire selection. The size is 160/80-15 and I know on a bike I had in the past I was able to go a size bigger in the rear. So am I able to order a 170/80-15 on the Phantom, which would offer me more selections?
