Well I just moved to an area where if I want to go skiing or drive out of the city in the winter I need to at LEAST carry winter chains with me, if not put them on the wheels during storms. I will be using winter tires... Now I SWEAR I remember some company advertising something new they called chains I believe. It kind of wrapped around the tire as a belt, and putting it on involved rolling the car forward slightly. Rather than the regular chains criss-crossing, it was mainly a wide belt with I believe metal teeth or something for traction. Am I crazy, or did I just see some obscure product that never made it to production?
