This pneumatic radial tire for a passenger vehicle comprises a carcass composed of plies of radially arranged cord spanning between a pair of bead parts in a toroidal shape. The cross-sectional width SW (mm) and the outer diameter OD (mm) of the tire satisfy a prescribed relational expression. At least one sound-blocking body is provided to the inner surface of the tire, the sound-blocking body being provided in at least the center region and the shoulder region, and the thickness of the sound-blocking body when measured in a direction orthogonal to the inner surface of the tire being such that the maximum thickness Ts in the shoulder region is greater than the maximum thickness Tc in the center region.
该乘用车用充气子午线轮胎配备有胎体,该胎体包括径向配置的帘线的帘布层,所述胎体环状地跨设在一对胎圈部之间,并且轮胎的截面宽度SW(mm)和外径OD(mm)满足规定的关系式。在轮胎的内表面设置至少一个降噪器,降噪器至少设置在中央区域和胎肩区域中,当在与轮胎的内表面正交的方向上测量时,降噪器的厚度为胎肩区域中的最大厚度Ts大于中央区域中的最大厚度Tc。
