sand tires have a much more brittle stiffer rubber compound than actual snow tires, this only gets amplified with colder temperatures,,, essentially you would be just trowing these tires away. if you want an actual snow set up do it right the first time.. maxxis, kenda and i believe AMS make great snow tires that have cold weather compounds and are designed to conform and float atop the snow unlike a sand tire in sand which is designed to dig in and move away the earth as fast as possible
