i'm going to go with tire chains i think, use the torque instead of rpm. sled tracks are the best to run on,snow cat grooming is like a highway as fast as you wanna go!in the powder everything just high centers then the winch gets a workout. chains would be good in the mud too. other option which i've done to my cr 250 dirt bike would be expensive is studs, studs cost lots then new rubber and rims would be easier but if there is snow 6 months of the year you don't have to deal with busted chains. just flats
