Abstract
A tread pattern of a pneumatic tire is provided with two outer circumferential main grooves, and at least one inner circumferential main groove provided between the outer circumferential main grooves. A tread profile line of a first land portion between the outer circumferential main grooves protrudes 1 mm or less with respect to a first arc shape formed so as to pass through edge ends on the respective inner sides of the outer circumferential main grooves and edge ends on both sides of the inner side circumferential main groove. Furthermore, a tread profile line of a second land portion on the outer side of the outer circumferential main grooves in a tire width direction protrudes 1 mm or less with respect to a second arc shape which passes through edge ends on the outer side of the outer circumferential main grooves.
