The invention discloses a snowfield tire pattern, which relates to a tire pattern. The snowfield tire pattern comprises 3-5 longitudinally-arranged pattern folding grooves, a cutter groove is formed between every two adjacent pattern folding grooves, the cutter grooves are longitudinally formed, the cutter grooves are connected with the pattern folding grooves located in the two sides of the cutter grooves through a plurality of 3D wavy thin grooves, and the 3D wavy thin grooves are transversely formed. The longitudinal pattern grooves adopt a folding groove design and have the same depth, andthe two side walls of each pattern folding groove are respectively provided with a plurality of fine cutter groove patterns, so that the braking force of the tire is improved; the angle between the middle pattern folding groove and the vertical normal of the tread is 10-20 degrees; the vertical normal angles of the edge pattern folding grooves and the tread are designed in a variable angle mode,the variable angle range is 10-20 degrees, the adjacent first pattern blocks and the adjacent second pattern blocks are arranged in a variable pitch mode, resonance generated by air in the pattern grooves is effectively reduced when the tire runs, and tire noise is lowered.

    本发明一种雪地轮胎花纹涉及轮胎花纹,具体涉及一种雪地轮胎花纹,包括3‑5条纵向设置的花纹折沟,相邻花纹折沟之间均设置有刀槽,所述刀槽纵向设置,所述刀槽与位于该刀槽两侧的花纹折沟均通过若干个3D波浪形细沟相连,所述3D波浪形细沟均横向设置;本发明的纵向花纹沟采用折沟设计,深度相同,花花纹折沟的两侧壁上均设置有若干个细小刀槽纹,提高了轮胎制动力;中部花纹折沟与胎面垂直法线角度为10‑20度,边部花纹折沟与胎面垂直法线角度为变角度设计,变角度范围为10‑20°,结合相邻第一花纹块和相邻第二花纹块均为变节距设置,有效的减少轮胎行驶时花纹沟空气产生共鸣,降低轮胎噪音。
