The invention relates to the technical field of radial tires, and discloses a radial tire with ultralow passing noise, the radial tire comprises a cord fabric layer, a belted layer, a cap ply and a tread which are sequentially arranged from inside to outside, and at least two adjacent components in the cord fabric layer, the belted layer, the cap ply and the tread are made of different materials; the wire harness angle of the belted layer is 27-35 degrees, and the torsional elastic coefficient of the tire under the maximum load of 70%-80% is 65 N.m/deg to 75 N.m/deg; at least two adjacent parts are made of different materials, so that the noise of the internal cavity is weakened when being transmitted outwards; the wire harness angle of the belted layer is controlled to enable the torsional elastic coefficient to be 65 N.m/deg to 75 N.m/deg, so that the tire can meet the requirement of the first grade of the fourth stage of the European Tagon Method Grade.
本发明涉及子午线轮胎技术领域,公开了一种具有超低通过噪音的子午线轮胎,包括由内向外依次设置的帘布层、带束层、冠带层以及胎面,所述帘布层、带束层、冠带层以及胎面中至少两个相邻部件采用不同的材质;所述带束层的线束角度为27°~35°,并使得所述轮胎在70%~80%最大负荷下的扭转弹性系数为65N.m/deg~75N.m/deg;至少存在两个相邻部件采用不同的材质,使内部的空腔噪音在向外传递时遭到削弱;控制带束层线束角度使扭转弹性系数为65N.m/deg~75N.m/deg,使轮胎能够满足欧洲标签法草案第四阶段第1等级的要求。
