The invention relates to the field of tire patterns, and discloses a multi-dimensional depth groove four-season tire which is provided with a plurality of multi-dimensional grooves and cutter grooves. A stepped groove bottom with equal width and three-dimensional depth is arranged in the multi-dimensional groove, the stepped groove bottom comprises a first groove bottom, a second groove bottom and a third groove bottom, and the depths from the groove bottoms to the tread are 2 mm, 4 mm and 6 mm in sequence; the included angle between the groove walls of the two side edges and the longitudinal direction is 1-2 degrees, the included angle between the groove wall between the first groove bottom and the second groove bottom and the longitudinal direction is 1-2 degrees, and the included angle between the groove wall between the second groove bottom and the third groove bottom and the longitudinal direction is 2-3 degrees; and the intersection point of the bottom of the groove is subjected to fillet treatment, the fillet R of the external corner is 0.4-0.6, and the fillet R of the internal corner is 0.1-0.3. The arrangement of the multi-dimensional grooves can effectively improve the snowfield traction force, the snowfield road holding force and the water sliding performance of ice, snow and wet lands of the tire, and the resonance phenomenon is completely eradicated; due to the arrangement of the sawtooth-shaped three-dimensional cutter grooves, the ground gripping of the tires can be further improved; the pattern blocks are asymmetrically staggered, so that the rolling noise of the tire can be greatly reduced.
本发明涉及轮胎花纹领域,公开了一种多维深度沟槽四季轮胎,该轮胎上设置有多个多维沟槽和刀槽。所述多维沟槽内部设置有等宽的三维深度的阶梯式沟底,阶梯式沟底包括第一沟底、第二沟底和第三沟底,上述沟底距离胎面的深度依次为2mm、4mm、6mm;两侧边缘沟壁与纵向夹角为1°‑2°,第一沟底与第二沟底间的沟壁与纵向夹角为1°‑2°,第二沟底与第三沟底间的沟壁与纵向夹角为2°‑3°;沟底交点处做圆角处理,阳角圆角R0.4‑R0.6,阴角圆角R0.1‑R0.3。多维沟槽的设置能够有效提高轮胎的雪地牵引力、雪地抓地力和冰雪湿地的水滑性能、杜绝共振现象;锯齿状三维刀槽的设置能够进一步提升轮胎抓地;花纹块非对称交错布置可大幅度降低轮胎的滚动噪。
