The present invention provides a pneumatic tire for passenger cars comprising bead cores, a carcass layer, a tread portion, and side wall portions, wherein a rubber reinforcing layer having a crescent-shaped cross-section and at least one sheet of a rubber-filament fiber composite having a thickness measured under a pressure of 20 g/cm<2> of 0.05 to 2.0 mm which is formed from a rubber component and filaments having a diameter or a maximum cross-sectional dimension of 0.0001 to 0.1 mm and a length of 8 mm or more are disposed in said side wall portions and reinforcing cords of carcass plies are made of an aliphatic polyamide fiber having a melting point of 250 DEG C or higher. Deterioration of adhesion in carcass ply does not take place during use, particularly during use in a run-flat condition, and the pneumatic tire shows excellent durability. <IMAGE> |
