Zusammenfassung: | To provide a pneumatic tire formed in a rib pattern, which can suppress deterioration in steering safety on a dry road surface while improving wet performance.SOLUTION: In a pneumatic tire 1, a plurality of ribs 20 extending in a tire circumferential direction TC are formed by a plurality of main grooves 10 extending in the tire circumferential direction TC in a tread part 2. In the ribs 20 are formed circumferential sipes 30 extending in the tire circumferential direction TC. In only edge parts positioned closer to outside of a vehicle than a tire equator line CL in a posture in which the tire is mounted on a vehicle, of both edge parts positioned at the main grooves 10 and at mouths of the circumferential sipes 30 are formed circumferential chamfer parts 40 extending in the tire circumferential direction TC.SELECTED DRAWING: Figure 1
【課題】リブパターンに形成された空気入りタイヤにおいて、ウェット性能を向上させながら、ドライ路面における操縦安定性の低下を抑制できる空気入りタイヤを提供する。【解決手段】空気入りタイヤ1は、トレッド部2にタイヤ周方向TCに延びる複数の主溝10によってタイヤ周方向TCに延びる複数のリブ20が形成されている。リブ20にはタイヤ周方向TCに延びる周方向サイプ30が形成されている。主溝10及び周方向サイプ30の口元に位置する両縁部のうち、車両装着姿勢で、タイヤ赤道線CLよりも車両外側に位置する縁部にのみ、タイヤ周方向TCに延びる周方向面取り部40が形成されている。【選択図】図1 |
