摘要： A pneumatic tire 10, in which at least one rib groove 12 extended in a tire circumferential direction is formed on a tread surface portion T of a tread portion 11, and portions 13 discontinuous in terms of rigidity are formed in a circumferential direction of rib lines B formed by the rib groove 12, the discontinuous portions 13 causing variations of tire axle force. Rigidity changing portions 20 which cancel the variations of the tire-axle force are provided in the rib groove 12, the variations being caused by the discontinuous portions 13. Thus, vibrational force to an axle is lowered, and pattern noise caused thereby is reduced effectively.

摘要： This invention relates to a tire suitable in a passenger car, particularly a tire being high in the resistance to hydroplaning on a wet road surface and low in the tire noise and having an asymmetric tread pattern. In such a tread pattern that at least two circumferential grooves extending along an equatorial plane of the tire are formed in a region of a tread surface at an axially inner side with respect to the equatorial plane in the mounting on the vehicle and at least one circumferential groove is formed in a region at an axially outer side thereof, a circumferential groove nearest to the equatorial plane of the tire among the circumferential grooves arranged in the axially inner side region has a width wider by 20% or more than an average groove width of the tire and a circumferential groove arranged toward a side of a tread end at the axially inner side region has a width corresponding to 90-110% of the average groove width, and the circumferential groove nearest to the equatorial plane of the tire at the axially outer side region has a width narrower by 10% or more than the average groove width, whereby the resistance to hydroplaning and the controllability of tire noise, which have a conflicting relation in the prior art, are established in a higher level.
