Abstract

Provided is a pneumatic tire comprising a carcass, a reinforcing layer, and a cap tread, wherein the following inequalities are satisfied, (1) A 2 − A 1 > 0 (2) L 1 / L 2 > 0.30 (3) 30 ° CE * c > K / A 2 − A 1 × L 1 − L 2 × 0.3 <img class="EMIRef" id="9a0e1778-f6ea-4b29-9d88-9fa5e978fda3-ia03" /> (where K is 310) where A<1> represents an angle, in degrees, at which a carcass cord inclines from a tire circumferential direction at a position on a tire center line, A<2> represents an angle, in degrees, at which the carcass cord inclines from the tire circumferential direction at a tire maximum width position, L<1> represents a land ratio, in %, of a region including a tire equator, L<2> represents a land ratio, in %, of a pair of regions including tread ends, 30°CE*c represents a complex elastic modulus at 30°C of a rubber composition constituting the cap tread, and K represent a constant.
