The invention discloses a durable bus tire which comprises a sidewall and apex formed by upper filling rubber and lower filling rubber, and sidewall rubber, wear-resistant rubber, supplement rubber, knife-shaped rubber, the upper filling rubber, the lower filling rubber, inner-layer rubber and rectangular rubber are attached to the side, facing the inner side of the tire, of the apex. The width WB of the cross section of the tire and the width WA of the tread of the tire meet the following relation: WB = (1.11-1.19) * WA, the height H of the cross section of the tire and the height Hd of the lower cross section of the tire meet the following relation: Hd = (0.96-1.13) * H, and the height Hs l from the lower endpoint of the tire side to the bonding line (C) of the rim and the height Hd of the lower cross section of the tire meet the following relation: Hs l = (0.13-0.23) * Hd; according to the durable bus tire, the shear stress at the tire body end point of the tire bead part is reduced, and the energy loss of the filling rubber material of the tire bead part in the driving process is reduced, so that the tire has the characteristics of durability.

    本发明公开了一种持久耐用的公交轮胎,包括胎侧和由上填充胶、下填充胶形成的三角胶,所述三角胶朝向轮胎内侧的一侧贴合有胎侧胶、耐磨胶、补充胶、刀型胶、上填充胶、下填充胶、内层胶、矩形胶,所述轮胎断面宽WB与轮胎行驶面宽WA满足的关系为:WB=(1.11~1.19)×WA,所述轮胎断面高H与轮胎下断面高Hd满足关系:Hd=(0.96~1.13)×H,所述胎侧下端点到轮辋着合线(C)高度Hs l与轮胎下断面高Hd满足关系:Hs l=(0.13~0.23)×Hd;该持久耐用的公交轮胎,降低胎圈部胎体端点处的剪切应力,降低行驶过程中胎圈部填充胶料的能量损耗,使轮胎具备持久耐用的特性。
