发明名称 空気入りタイヤ
摘要 A pneumatic tire includes at least three circumferential grooves extending in a tire circumferential direction in the tread portion, and at least four ribs defined by the at least three circumferential grooves, the at least four ribs extending in the tire circumferential direction. At least two of the ribs including the rib disposed on a first side of a tire equatorial plane in a tire width direction and the rib disposed on a second side protrude to an outer side in a tire radial direction beyond a profile line of a tread surface when viewed in the meridian cross section. The protruding amount decreases in order from the first side in the tire width direction to the second side, and the groove surface area ratio of the tread surface is greater on the second side of the tire equatorial plane in the tire width direction than on the first side.
