The Best Snow Tires for 2025/26 P5 of 5

In last place was the Marshal iZen KW31. The fact that it was out performed by the central european winter tire in the snow sums it up, but the tire under performed in almost every category. Given this tire is designed for extreme climates but was nowhere near the group in snow and ice, it might be one to avoid.
