The invention provides a tire with an improved heat dissipation effect. The tire comprises a sidewall. A plurality of protruding parts are arranged on an outer peripheral surface of the sidewall alonga radial direction and a circumferential direction of the tire; each protruding part is provided with a contracted tip upper part in the direction parallel to an axial direction of the tire; a heightH of each protruding part is equal to (0.0015 to 0.01)*(J.DIA-D.DIA); and a width W of the bottom of each protruding part is equal to (0.3-0.7)*H, J.DIA is an outer diameter of the tire on a mold, D.DIA is a fitting diameter of the tire on the mold, and a groove area sunken inwards relative to a base surface of a bottom end of each protruding part is formed between every two adjacent protruding parts in the radial direction of the tire and/or the circumferential direction of the tire. By improving a heat dissipation effect, the temperature outside and inside the tire is reduced, and then durability of the tire is improved; meanwhile, an influence on a rolling resistance of the tire is also considered so that the rolling resistance of the tire is not reduced while the durability of the tire is improved; and the influence of vehicle aerodynamics is also considered, and the aerodynamic performance of the vehicle cannot be reduced while the durability of the tire is improved.

    本发明提供一种改善散热效果的轮胎,包括胎侧,该胎侧外周面上沿轮胎径向和轮胎周向具有多个突出部,每个所述突出部在平行于轮胎轴向上具有收缩的尖端上部,该突出部的高度H=(0.0015~0.01)*(J.DIA‑D.DIA),突出部的底部宽度W=(0.3~0.7)*H,其中J.DIA为模具上轮胎外直径,D.DIA为模具上轮胎着合直径,在轮胎径向和/或轮胎周向上相邻的两个突出部之间开设有相对于突出部底端基面向内凹陷的凹槽区。本发明通过提升散热效果而实现轮胎外部、内部温度的降低,进而提升其耐久性能;同时该发明也考虑到对轮胎滚阻的影响,在提升轮胎耐久性能的同时不会降低轮胎的滚阻性能;同时该发明也考虑到车辆空气动力学的影响,在提升轮胎耐久性能的同时不会降低车辆的空气动力学性能。
