The invention relates to the technical field of tires, and discloses an anti-eccentric-wear low-rolling-resistance truck tire which is characterized in that the radial distance from the center point A of a tread to the intersection point B of the outer side groove wall of a pattern groove and the tread forms a rolling radius difference h1; the radial distance from the tread center point A to the tire shoulder point C forms a rolling radius difference h2; the distance L from the intersection point B to the tire shoulder point C is the width of the pattern strip; and the ratio of the difference value of the rolling radius difference h2 and the rolling radius difference h1 to the width L of the pattern strip is 0.08-0.13. By adjusting the diameter difference of the tread of the tire, the relation between the arrangement of the protection grooves and the diameter difference of the tread is stipulated, the relative slippage of the tire shoulder relative to rubber in the middle of the tire crown is fully reduced, the eccentric wear resistance of the tire is effectively improved, and meanwhile the wear resistance of the tire is guaranteed.
本发明涉及轮胎技术领域,公开了一种抗偏磨低滚阻载重轮胎,胎面中心点A到花纹沟外侧沟壁与胎面的交点B的径向距离,形成滚动半径径差h1;胎面中心点A到胎肩点C的径向距离,形成滚动半径径差h2;所述交点B到胎肩点C的距离L为花纹条的宽度;滚动半径径差h2与滚动半径径差h1的差值与花纹条宽度L的比例为0.08~0.13。通过对轮胎行驶面径差的调整,规定防护沟设置与行驶面径差的关系,充分减小胎肩相对胎冠中部橡胶的相对滑移量,有效提高轮胎的抗偏磨性能并同时保证轮胎的磨耗性能。
