    • The tire has a plurality of radially outer rubber components defining a radially outer surface (S1) exposed to fluids having a relative displacement with respect to the rotating tire. At least one radially outer component has projections, the projections being defined by first sides (2) and second sides (2′) of unequal length. The first sides (2) have a greater length, delimiting therebetween an angle α ranging from 5° to 60° and forming at their intersection an apex (P). The projections protrude by a height (h) from the radially outer surface (S1) from which said first and second sides originate, the height (h) ranging from 0.2 to 100 micrometers. In more than 75% of the projections, any plane tangent to the first side (2) of the projection cuts the radially outer surface (S1) at an acute angle.
    • 轮胎具有多个径向外部橡胶部件,其限定暴露于相对于旋转轮胎的相对位移的流体的径向外表面(S1)。 至少一个径向外部部件具有突起,突起由不等长度的第一侧面(2)和第二侧面(2')限定。 第一边(2)具有更大的长度,在它们之间限定了从5°至60°的角度α,并在它们的交点处形成顶点(P)。 突出部分从距第一和第二侧起始的径向外表面(S1)的高度(h)突出,高度(h)为0.2至100微米。 在超过75%的突起中,与突起的第一侧(2)相切的任何平面以锐角切割径向外表面(S1)。
