Pneumatic tire

Abstract

It is an object of the present invention to provide a pneumatic tire capable of improving the riding comfort performance while maintaining the steering stability performance. The pneumatic tire is characterized in that a mounting orientation to a vehicle is designated, and at least four land portions are included with respect to a tread portion. A total ground contact area of the outside shoulderland portion (5) and the outside quarter land portion (4) is larger than a total ground contact area of the inside quarter land portion and the inside shoulder land portion. The outside quarter land portion (2) has a first circumferential sipe (43) extending in a tire circumferential direction. On the first circumferential sipe (43), a chamfered first inclined surface portion (45) extending in thetire circumferential direction is provided between a vehicle outside inner wall of the first circumferential sipe (43) and s surface of the outside quarter land portion (4).

Description

technical field

[0001] The present invention relates to a pneumatic tire including a tread portion. Background technique

[0002] Conventionally, it is known that the ground contact pressure of the tread portion of a pneumatic tire is higher in the vehicle outer region facing the vehicle outer side based on the tire equator than in the vehicle inner region facing the vehicle inner side based on the tire equator when cornering. high. Therefore, in order to improve steering stability, it is necessary to increase the ground contact area of ​​the vehicle outer region of the pneumatic tire, or to set the rigidity of the tread portion high (see Patent Documents 1-4).

[0003] However, if the ground contact area of ​​the tire is increased or the rigidity of the tread portion is set high, it becomes difficult for the tire to absorb the unevenness of the road surface, and the vibration and noise increase, resulting in a decrease in riding comfort. That is, it can be said that handl...
