A pneumatic tire comprising a carcass having two opposite beads and extending from one bead to the other bead, a tread portion disposed radially outwardly of the carcass and extending in a circumferential direction of the tire, a belt of steel cord material disposed between the carcass and the tread portion, the belt having two laterally opposite end portions, and a reinforcing layer disposed between the tread portion and the belt. The reinforcing layer is formed by spirally hooping a continuous ribbon material on the belt. The continuous ribbon material is composed of a plurality of nylon cords covered with rubber. The reinforcing layer is varied in cord density laterally of the tire by varying a hooping pitch of the ribbon material laterally of the tire and hooping the ribbon material in two or more layers. |
