From November to February, the tires experienced temperatures as high as 12 degrees Celsius and as low as -26 degrees Celsius, as well as surfaces ranging from very clear asphalt to ice and snow drifts. Consequently, the tires performed admirably, both on ice and snow (rated at significant negatives) and on snow porridge (rated at 0-5). And in general, I've gotten nothing but rave reports from using my fifth set of TOYO all year round.
