Easy mounted tyre wheel rim flange

一种轮胎，具有两个用于与轮辋安装支座接触的胎边(2)，和两个侧壁(1)，该轮胎具有构成该轮胎胎体加强件(3)的第一加强线(4)，每个胎边具有用于由至少一个环向排列的第二加强线(7)构成的胎体加强件(3)的固定结构(20)，该第二加强线通过固定橡胶材料(9)与该胎体加强件(3)相邻的部分结合，该橡胶材料具有至少等于30MPa的10％变形的弹性模量，该轮胎的特征在于，至少在该胎体加强件(3)固定结构(20)轴向一边，具有称为"脱开混合物"的橡胶混合物(11、12)，该脱开混合物具有在10％变形时小于该固定混合物弹性模量一半的弹性模量。 The tyre consists of a reinforced crown, two beads (2) that make contact with wheel rim seats, and two sidewalls (1) connecting the crown to the beads, which contain an anchoring structure (20) for the tyre's carcass reinforcement (3). Each bead contains a rubber separating mixture (11, 12) on either side of the carcass reinforcement anchoring structure that has a modulus of elasticity at 10 per cent deformation that is lower than half that of the anchoring rubber mixture (9). Each bead also has a protective outer layer (50) with a modulus of elasticity at 10 per cent of at least 10 MPa.
