Due to a stupid local law, you can only drive a motorcycle from November to March if it has "winter" tires on, despite the fact that most of the time the roads are fine. Sure, you wouldn't drive such bike on snow anyway, but I haven't had any problems even with "summer" tires during the nicer days. Has anybody had luck finding "winter" tires for their VStar? Tires must have "M+S" (or equivalent) marking. The closest I've found is Continental TKC-70 (Continental Motorcycle Tires TKC 70), but these are enduro tires and slightly different in size. What would it take to modify such tires to fit XVS1100 2007 (standard tires are 130/90B16, 170/80B15)?
