The invention relates to a tyre (1), and more particularly to a tyre (1) intended for private passenger vehicles and comprising at least one sidewall (3) having a sidewall (3) projection, in order to reduce aerodynamic resistance and thus resistance to wheel advancement, thereby helping to reduce fuel consumption and thus CO2 emissions, and the bulges of the tire side walls (3) are close to the joint of the tire and the tire mounting rim (2). According to the invention, when the tyre (1) is mounted on the rim (2) and inflated to a pressure defined by the "ETRTO" standard, the radially inner end I of the projection (6) is arranged radially inside the radially outermost point J of the rim flange (21) by a radial distance H1 at most equal to 10 mm or radially outside the radially outermost point J of the rim flange (21) by a radial distance H1 at most equal to 4 mm.
本发明涉及一种轮胎(1),更具体地,旨在用于私家客运车辆并且包括至少一个具有胎侧(3)突起物的胎侧(3)的轮胎(1),以减小空气动力学阻力并且因此减小车轮前移的阻力,从而有助于降低燃料消耗并且因此减少CO2排放,所述胎侧(3)突起物靠近轮胎与轮胎安装轮辋(2)的连接处。根据本发明,当轮胎(1)安装在轮辋(2)上并且充气至由“ETRTO”标准限定的压力时,突起物(6)的径向内端I以至多等于10mm的径向距离H1沿径向布置在轮辋凸缘(21)的径向最外点J的内侧,或者以至多等于4mm的径向距离H1沿径向布置在轮辋凸缘(21)的径向最外点J的外侧。
