In a pneumatic tireaccording to the present invention, as an average sipe interval hc defined by an average interval of sipes adjacent to each other in a tire circumferential direction in a center portion block, which is a block arranged at a position including a tire equatorial line, and an average sipe interval hs is defined in a shoulder portion block, which is a block located at an ground contact end in a tire width direction, a relation of 1.05&#x2264;(hs/hc)&#x2264;4.00 is fulfilled.

Tire

A tire in which a reinforcement layer and a tread section are laminated in this order from the inside toward the outside in a radial direction of the tire. The tread section includes an inner base layer, an outer base layer, and a cap layer that are laminated in this order from the inside toward the outside in the radial direction of the tire. The cap layer is made of a material of which a modulus of elasticity and a loss tangent are lower than those of a material of the outer base layer. The inner base layer is made of a material of which a modulus of elasticity is lower than that of a material of the cap layer.
