Abstract:
A pneumatic tire includes, in a tread portion, a pair of circumferential main grooves extending and a land portion provided between the pair of circumferential main grooves and extending in the tire circumferential direction. The land portion includes a bulging portion bulging in a second arc shape in a tire radial direction as a sectional outline of a tread surface of the land portion and chamfered portions connected to the bulging portion and extending straight toward respective groove walls of the circumferential main grooves. A portion of the bulging portion bulges in the tire radial direction with respect to a virtual tread profile line which is determined by a first arc shape in a sectional shape of the tread portion. A maximum bulging amount is 0.1 to 0.8 mm. The virtual tread profile line extends across the chamfered portions.
