重载荷用轮胎
摘要：
本发明的重载荷用轮胎，维持湿地性能并提高耐不均匀磨损性能。在经过胎肩主沟(12)的沟底的轮胎径向线上，从带束层(7)的外表面(7s)到轮胎的内腔面的距离(t1)为15～23mm。各胎肩主沟(12)的沟宽度大于中央主沟(11)的沟宽度。中央陆地部(20)的平均宽度(Wc)、中间陆地部(30)的平均宽度(Wm)以及胎肩陆地部(40)的平均宽度(Ws)的比Wc︰Wm︰Ws为1.00︰1.00～1.08︰1.03～1.13。在中间陆地部(30)设置有多条中间横沟(31)。在胎肩陆地部(40)设置有多条胎肩横沟(41)。胎肩横沟(41)的沟宽度大于中间横沟(31)的沟宽度。胎肩横沟(41)相对于轮胎轴向的角度(θs)大于中间横沟(31)相对于轮胎轴向的角度(θm)。
摘要（英）：

A heavy duty tire is disclosed. The distance from the radially outer surface of a belt layer to the tire s inner surface is 15 to 23 mm when measured along a tire radial direction line passing through the bottom of a shoulder main groove. The width of the shoulder main groove is more than the width of a center main groove. The ratio Wc:Wm:Ws of the average width Wc of a center land portion, the average width Wm of a middle land portion, and the average width Ws of a shoulder land portion is 1.00:1.00 to 1.08:1.03 to 1.13. The middle land portion is provided with a plurality of middle axial grooves. The shoulder land portion is provided with a plurality of shoulder axial grooves. The width of the shoulder axial groove is more than the width of the middle axial groove. The angle (theta)s of the shoulder axial groove is more than the angle (theta)m of the middle axial groove with respect to the tire axial direction.
