Abstract
This invention provides a pneumatic tire that balances low fuel consumption and ride comfort. The pneumatic tire (1) has a profile (2) including a contact surface (3a) and a first side outer surface (6a). The tread portion (3) has a first shoulder circumferential groove (4A) and a first shoulder land portion (5A) divided by the first shoulder circumferential groove and a first contact end (Te1). In the contact surface, a first imaginary line (L1) has a first angle (θ1) of 74-80° relative to the tire radial direction. In the first side outer surface, a second imaginary line (L2) has a second angle (θ2) of 36-40° relative to the tire radial direction. The tread portion has a belt layer with belt cords (11c) arranged therein. The ride comfort index λ×t / TW, defined by the angle λ (°) of the belt cords relative to the tire circumferential direction, the distance t (mm) between the first contact end and the tire equator, and the contact width TW (mm), is 1.0-2.0.
