The invention belongs to the field of radial tires. In order to solve the problem that the traditional all-weather tire is relatively insufficient in ice, snow and dry wet land performance, the invention provides the strong-ground-gripping all-weather radial tire of the car. Four straight longitudinal grooves with unequal widths are distributed on the tread, pattern blocks A, pattern blocks B and pattern blocks C are arranged among the straight longitudinal grooves, and transverse grooves I are distributed on the pattern blocks A; form II transverse grooves are distributed in the pattern block A and the pattern block B, form II transverse grooves are distributed in the pattern block B and the pattern block C, the form II transverse grooves in the two pattern blocks are in 180-degree mirror images and are in butt joint through oblique lines of 30-38 degrees, and the form I transverse grooves in the pattern block A and the form II transverse grooves in the pattern block B are in butt joint through oblique lines of 60-70 degrees. Fine three-dimensional cutter grooves in a form a, a form b and a form c are respectively distributed on the pattern block A, the pattern block B and the pattern block C, the fine three-dimensional cutter grooves in the form a are trapezoidal zigzag cutter grooves, and the fine cutter grooves in the form c are arc grooves. Through the design of the strong grip special area, the grip of ice, snow and dry and wet lands is effectively improved at the same time.
本发明属于子午线轮胎领域。为解决传统全天候轮胎冰雪及干湿地性能相对不足的问题,本发明提供一种强抓地全天候轿车子午线轮胎。胎面分布4条不等宽直纵沟,直纵沟之间为花花纹块A、花纹块B和花纹块C,花纹块A上分布形式Ⅰ横沟;花纹块B和花纹块C上分布形式Ⅱ横沟,且上述两种花纹块上的形式Ⅱ横沟互为180°镜像并以30°‑38°斜线对接,花纹块A上的形式Ⅰ横沟与花纹块B上的形式Ⅱ横沟以60°‑70°斜线对接;花纹块A、花纹块B和花纹块C上分别分布形式a、形式b和形式c的细小三维刀槽,形式a细小三维刀槽为梯形曲折刀槽,形式c细小刀槽,为弧线沟槽。本发明通过强抓地特区设计,有效同时提升冰雪及干湿地抓地力。
