It changed last yr I guess. In past going up mountain in winter we normally rode with a local gal who had a AWD with studded tires. Plus she used to live up there yr round. Now just has a cabin. Now I’m driving up there in 4wd. As I read the law. I do NOT have to chain up during traction issues. IF my tires are Mud & Snow tires? But I do with mild off road/ all season tires? But in either case I need to have at least one set of chains with me? I actually have avoided ever putting chains on lying in snow. . In a semi heated garage the few times I have put them on. With tarp on cement at worst... If they MUST be dedicated snow tires. Buying a basic set, junkyard rims, some tire shops offer free swapping winter, summer, with balance if you buy 4... Might be worth it. I’m hoping the overly aggressive tires might get me a pass. Just if I know law I might get by. Also if I don’t have to use chains unless really bad. I will buy cheap ones. If I expect to put 40 miles 4+ a yr. might as well get quality.
