The invention relates to the technical field of tires, and discloses a snowfield light truck tire. The tire adopts a double-layer tread design, the upper tread rubber adopts a special extremely cold region formula design and an ultra-low hardness design, the glass transition temperature Tg is lower than-50 DEG C, and the hardness is 48-56; the lower tread rubber adopts a low glass transition temperature design and a medium hardness design, the glass transition temperature Tg is lower than-45 DEG C, and the hardness is 60-70. By means of the design, the tire can provide shorter braking distance and better road holding force when running on the snowfield, and meanwhile the high speed and durability of the tire are guaranteed.
