<p>A tire (2) according to the present invention includes a bead (8) having an apex (28), a carcass (10) and a reinforcing layer (16). The carcass (10) includes a carcass ply having a carcass cord constituted by a polyethylene naphthalate fiber. The carcass ply is constituted by a body extended from an equator plane toward the bead (8) and a turned-up portion extended outward in a radial direction. The reinforcing layer (16) is interposed between the body and the turned-up portion. A ratio of a height in the radial direction from a bead base line to an upper end (54) of the reinforcing layer (16) to a tire sectional height is equal to or higher than 45%. A thickness of the reinforcing layer (16) is equal to or greater than 0.3 mm and is equal to or smaller than 2.5 mm. A hardness of the reinforcing layer (16) is equal to or greater than 70 and is equal to or smaller than 95.</p> |
