The invention discloses a double-side white sidewall winter tire which comprises a tread, the tread comprises a tire crown and a tire shoulder, patterns are arranged in the center of the tread, and the double-side white sidewall winter tire is characterized in that the groove bottom depth GD2 of the tire shoulder part and the groove depth GD1 of the tire crown part meet the relation that GD1 is equal to GD2, the groove depth GD1 of the tire crown part ranges from 8.0 mm to 11.0 mm, and the groove depth GD1 of the tire shoulder part ranges from 1.0 mm to 11.0 mm. The range of the ratio TDW/Sn of the tread grounding width TDW to the tire specification nominal section width Sn is 0.75-1.0, and the range of the shortest linear distance from the highest point to the tread grounding width point is 7.5-12.0; according to the winter tire with the double white tire sidewalls, through contour, structural design, pattern design and tire sidewall design, the problems that in the prior art, improvement of road holding force of a snow tire is not specifically considered, cost is selectively saved for the single-side white tire sidewall, and meanwhile the purpose of improving the decoration effect is achieved are solved, but the tire is not easy to deform when being used for a tire with a single guide pattern type. And a single-side white tire side cannot meet the requirements.
本发明公开了一种双边白胎侧冬季轮胎,包括胎面,所述胎面包括胎冠和胎肩,所述胎面中心设置花纹,其特征在于,所述胎肩部沟底深度GD2与胎冠部沟深度GD1满足的关系为GD1=GD2,所述胎冠部沟深度GD1的范围为8.0‑11.0mm,所述胎面接地宽度TDW与轮胎规格名义断面宽Sn的比值TDW/Sn范围为:0.75‑1.0,最高点到胎面接地宽度点最短直线距离范围为7.5‑12.0;该双边白胎侧冬季轮胎,通过轮廓、结构设计、花纹设计和胎侧的设计,解决了现有技术主要是对雪地胎抓地力提升并未具体考虑以及单边的白字胎侧,选择节约成本的同时,达到了增加装饰效果的目的,但针对单导向花纹类型的轮胎时,单边白胎侧就无法满足需求的问题。
