所述沟槽角度：沟槽两侧壁间的夹角＝α+β，角α、β为花纹沟侧壁与轮胎径向夹角，0°＜α、β＜45°；
沟槽宽度：s，花纹沟深度：H，排石块与沟槽侧壁连接处据胎顶花纹高度：h1，排石块设计高度：h2，花纹沟剩余深度：h3，排石块宽度：a，排石块长度：c；
0＜h1＜10mm，0＜h2＜H/2，0＜a＜s，0＜c＜50mm；
作为本发明进一步的方案：所述排石块顶部呈斜面设置，且靠近沟槽的一侧较低。
作为本发明进一步的方案：所述排石块上端面开设有若干个凸起条。
作为本发明进一步的方案：所述排石块面向另一侧沟槽内壁的端部为尖端面。
作为本发明进一步的方案：所述沟槽两侧的排石块采用间隔分布。
作为本发明进一步的方案：所述排石块的材质与胎体材质相同。
 有益效果
与现有技术相比，本发明的有益效果是：本发明设计一种增强排石效果花纹沟线轮胎，轮胎花纹沟采用变角度花纹沟设计，花纹沟侧壁增加排石块设计，帮助胎面免受石子切割和损伤。
