<p>In the present invention, 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 edges on the respective inner sides of the outer circumferential main grooves and edges 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 edges on the outer side of the outer circumferential main grooves and which is formed of an arc having a radius of 75 to 95% of the radius of the circle of the first arc shape.</p> |
