The invention relates to the technical field of tires, in particular to a high-durability SUV tire which comprises two tire beads, a tire body and a tire side wall, and each tire bead comprises a tire bead core and apex extending from the tire bead core to the radial outer side of the tire; the tire body comprises a cord fabric layer which extends between the two tire beads; at least three cord fabric layers are arranged; the tire side wall is arranged on the surface, located on the axial outer side of the tire, of the cord fabric layer; the bending end points of the multiple cord fabric layers are arranged on one side of the tire side in a scattered mode; at least one cord fabric layer is bent and reversely wrapped around the tire bead core from the axial inner side to the outer side, and at least one cord fabric layer is bent and positively wrapped around the tire bead core from the axial outer side to the inner side. The cord fabric layer is firstly reversely wrapped and then positively wrapped, so that endpoint concentration is avoided while the rigidity of the tire body is improved, and shear heat generation is reduced.
本发明涉及轮胎技术领域,更具体而言,涉及一种高耐久SUV轮胎,包括两个胎圈、胎体和胎侧,所述胎圈,包括胎圈芯、以及从该胎圈芯向轮胎的径向外侧延伸的三角胶;所述胎体,包括在两个所述胎圈之间延伸的帘布层;所述帘布层至少设置三层;所述胎侧设置于所述帘布层位于轮胎的轴向外侧的表面;多层所述帘布层的弯折端点分散设置于所述胎侧一侧;至少一层所述帘布层围绕胎圈芯从轴向内侧朝向外侧弯折反包,至少一层所述帘布层围绕胎圈芯从轴向外侧朝向内侧弯折正包。通过帘布层先反包后正包,提高胎体刚性的同时避免端点集中,降低剪切生热。
