Abstract

Provided is a pneumatic tire comprising a carcass, a reinforcing layer, and a cap tread, wherein A<1>, A<2>, W<1>, W<2>, 30°C E*c and K satisfy the following inequalities: A 2 − A 1 > 0 ; W 1 / W 2 > 0.30 ; and 30 ° C E * c > K / A 2 − A 1 × W 1 − 0.3 × W 2 <img class="EMIRef" id="319565b1-a13a-4221-b004-e05963db8e68-ia01" /> where A<1> represents an angle of carcass cord inclined from the tire circumferential direction on the tire center line, A<2> represents an angle of carcass cord inclined from the tire circumferential direction at a tire maximum width position, W<1> represents a land part width of a land part closest to the tire center line among the land parts, W<2> represents a land part width of a land part adjacent to an outer side in a tire axial direction of the land part closest to the tire center line, 30°C E*c represents a complex elastic modulus at 30°C of the cap tread, and K represents a constant.
