So I'm looking at changing my rims on my 06 SG. Currently 16" spoke front and back, looking to go up to 18" in front and back. Thoughts on tire sizes? Going for Mich comm. as I have read great reviews for wet road riding here in PNW. Don't want to over load fender space just want a bit snugger of a fit. And if I upgrade front to 18" should leave back at 16" and get tire with taller side wall? Last bikes were softail custom and dyna wide glide so im new to changing up stuff on a bagger, and don't wanna compromise that Cadillac feeling ride I purchased it for. Thanks.
