发明名称 PNEUMATIC TIRE
摘要 PROBLEM TO BE SOLVED: To provide a pneumatic tire improved in noise performance while securing drainage performance.SOLUTION: A pneumatic tire is formed with at least one circumferential groove extending in a tire circumferential direction on a tread of a tread part, includes, in the circumferential groove, inclined surfaces extending while tilting with respect to the tire circumferential direction, and includes a plurality of projecting parts each having both ends in the tire width direction connected to circumferential groove walls. In the pneumatic tire, the projecting parts located in a grounding surface extend throughout the entire width in the tire width direction between the circumferential groove walls in the circumferential groove in a grounding state where the tire is mounted to an application rim, and a predetermined load is imposed by applying predetermined internal pressure, and, in a no-load state where the tire is mounted to the application rim, and predetermined pressure is applied, the projecting parts include two or more projections having inclined surfaces extending while tilting with respect to the tire width direction and separated from each other in the tire width direction, or projections having inclined surfaces extending while tilting with respect to a tire radial direction, and each having a size in the tire radial direction smaller than the circumferential groove depth.
