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.
本发明涉及轮胎技术领域,公开了一种雪地轻卡轮胎。该轮胎采用双层胎面设计,上胎面胶采用特殊极寒地区配方设计和超低硬度设计,玻璃化温度Tg低于‑50℃,硬度为48‑56;下胎面胶采用低玻璃化温度设计和中等硬度设计,玻璃化温度Tg低于‑45℃,硬度为60‑70。该设计可以让轮胎在雪地行驶时提供更短的制动距离和更好的抓地力,同时保证轮胎的高速和耐久性能。
