Abstract:
A pneumatic tire (10) according to the present invention includes a first side reinforcement layer (110) and a second side reinforcement layer (120). The first side reinforcement layer (110) has a plurality of reinforcement cords (110s), and the second side reinforcement layer (120) has a plurality of reinforcement cords (120s) each crossing the reinforcement cords (110s). Additionally, an inclination angle of each of the reinforcement cords (110s) and the reinforcement cords (120s) with respect to a circumferential line extending in a circumferential direction of the pneumatic tire (10) is 5 to 30 degrees. According to the pneumatic tire (10), high speed durability thereof can be further enhanced without reducing wear life of a shoulder portion thereof.
