..at least a dilemna as I make it. Considering getting SM wheels for the S but also considering two sets of tires for the S instead. I ride off road maybe 4-5 months out of the year here in CO (Denver is home) and spend a lot of time on the street year round. I wanted to maintain some street performance while also getting better off road performance for the times I am off road. Thinking about the SM wheels for late Sept. thru April then S wheels with better-than-death Wings for off road the other months. Not up for the 2k+ cost of the wheels and changes needed, and I do already enjoy the mountain twisties with the S as is a lot so...2 sets of tires intead? M6006 or the like for Spring and Summer with Trail Wings (or even more road oriented tire) for the other 7-8 months. Opinions? Thanks.
