In the present invention, a tread pattern of a pneumatic tire is provided with two outside peripheral direction main grooves, and at least one inside peripheral direction main groove provided between the outside peripheral direction main grooves. A tread profile line of a first land section between the outside peripheral direction main grooves protrudes 1 mm or less relative to a first arcuate shape formed so as to pass through edge ends on the respective insides of the outside peripheral direction main grooves and edge ends on both sides of the inside peripheral direction main groove. Furthermore, a tread profile line of a second land section on the tire-widthwise outsides of the outside peripheral direction main grooves protrudes 1 mm or less relative to a second arcuate shape which passes through the outside edge ends in the outside peripheral direction main grooves and which is formed in an arc having a radius of 75 to 95% of the radius of the circle of the first arcuate shape. |
