The present invention discloses a truck radial tire, and relates to the technical field of tire manufacturing, the truck radial tire comprises a tire crown, the tire crown is provided with a pattern main body position cutter groove, a tire crown pattern side ditch, a semi-closed area and an open area, the tire crown pattern saturation is 81-85%, the thickness of the pattern main body position cutter groove is 1.1 mm, and the width of the pattern main body position cutter groove is 1.2 mm. The value range of the pattern depth H1 of the tire crown pattern side ditch is 15-18 mm, the semi-closed areas and the open areas of the tire crown pattern middle ditch are alternately arranged, the semi-closed areas are provided with pattern groove locking bosses, and the value of the width W3 of the middle gap of the pattern groove locking bosses is 1-2 mm. According to the invention, under the condition that the wet land performance of the tire is basically harmless, the slippage of the tread caused by longitudinal force is reduced, the overall abrasion performance of the tread is improved, and the burnup performance can be improved to some extent.

    本发明公开了一种载重子午线轮胎,涉及轮胎制造技术领域,该轮胎包括胎冠,所述胎冠上设置有花纹主体位置刀槽、胎冠花纹边沟、半封闭区域、开放区域,所述胎冠花纹饱和度为81%~85%,所述花纹主体位置刀槽的厚度为1.1mm,所述胎冠花纹边沟的花纹深度H1取值范围为15~18mm,所述胎冠花纹中间沟半封闭区域和开放区域交替排布,所述半封闭区域设置有花纹沟锁紧凸台,所述花纹沟锁紧凸台中间间隙宽度W3的取值为1~2mm。本发明可以对轮胎湿地性能基本无害的情况下,减少胎面因纵向力而产生的滑移,改善胎面的整体磨耗性能,并能对燃耗性能有所提升。
