ABSTRACT:
A pneumatic tire comprising a radial carcass (5) of at least one carcass ply including a main body portion (3a) and a turnup portion (3b), and a reinforcing member (7) including at least two reinforcing layers. The at least two reinforcing layers (6a, 6b) are cross reinforcing layers (21) arranged so as to envelop at least the turnup portion of the radial carcass and cross cords of these layers with each other. Outer ends of the cross reinforcing layers, located outward from the turnup portion (3b) of the radial carcass in the widthwise direction of the tire, are outward from an outer end (13) of the turnup portion of the radial carcass in the radial direction of the tire. A crossing angle α between cords of adjacent cross reinforcing layers with respect to a circumferential direction (15) of the tire is more than50° but less than1300°.
