Abstract
Provided is a pneumatic tire comprising a carcass, a reinforcing layer, and a cap tread, wherein A<sub>1</sub>, A<sub>2</sub>, Da, Db, 30°C E*c and K satisfy the following inequalities:|A<sub>2</sub>-A<sub>1</sub>|>0; Db/Da>0.50; and 30°C E*c>K/{|A<sub>2</sub>-A<sub>1</sub>|×(Db-0.5×Da)}where A<sub>1</sub> represents an angle of carcass cord inclined from the tire circumferential direction on the tire center line, A<sub>2</sub> represents an angle of carcass cord inclined from the tire circumferential direction at a tire maximum width position, Da represents the shortest distance between the carcass cord and the belt cord, Db represents the shortest distance between the belt cord and the band cord, 30°C E*c represents a complex elastic modulus at 30°C of the cap tread, and K represents a constant.
