The invention discloses a VAN new energy tire with high wet skid resistance, low noise and low rolling resistance, which comprises radial grooves formed in the surfaces of a tire crown and a tire shoulder, and the radial grooves form an annular groove along the circumferential direction of the tire crown; the axial grooves are formed in the surfaces of the tire crown and the tire shoulder, the axial grooves are communicated with the radial grooves, the axial grooves are curved cutter grooves with bending angles, and the radial width of the axial grooves in the tire is 1-2 mm; the tire body has a shoulder sinking height SD and a sidewall height SH: 2.5% < = SD/SH < = 5%. The drainage capacity of the tire body is improved by arranging the radial grooves and the axial grooves with the narrow bending angles, the bending angles of the axial grooves can reduce noise under the condition that the drainage capacity is not affected, and the contact area of the tire body and the ground is restrained by restraining the radial side face curvature of the tire body. When the tire main body is in contact with the ground, the radial deformation can reduce the rolling resistance of the tire main body under the condition of not influencing drainage and noise, so that the tire main body has high wet skid resistance, low noise and low rolling resistance.
本发明公开了一种高抗湿滑、低噪音、低滚阻的VAN新能源轮胎,包括形成于胎冠和胎肩的表面的径向沟,该径向沟沿胎冠周向形成环形沟槽;形成于胎冠和胎肩表面的轴向槽,该轴向槽与径向沟连通,轴向槽形状为具有弯折角的曲线刀槽,轴向槽沿轮胎径向宽度为1mm‑2mm;轮胎主体存在肩部下沉高度SD和胎侧高度SH:2.5%≦SD/SH≦5%。通过设置径向沟和具有弯折角较窄轴向槽提高轮胎主体排水能力,轴向槽的弯折角能在不影响排水能力情况下降低其噪音,通过约束轮胎主体径向侧面曲率约束其与地面接触面积,使得轮胎主体与地面接触时径向变形能在不影响排水和噪音情况下降低其滚阻,实现轮胎主体高抗湿滑、低噪音和低滚阻。
