摘要： The reduction of noise in the rotation of the tire and the improvement of resistance to hydroplaning are established and also the resistance to uneven wear is improved, in which four circumferential main grooves 2-5 are formed asymmetrically, and a sum of groove volume in a circumferential direction in lateral grooves formed in a shoulder land part row 7 as a portion of an axially inner side per unit width is made smaller than a sum of groove volume in the circumferential direction in lateral grooves 11 formed in a shoulder land part row 9 as a portion of an axially outer side and a land part row 6 in a central region is rendered into a rib, and slant grooves 13 extending at an average inclination angle of not less than 45° with respect to a widthwise direction of the tread are arranged in a second inner land part row 8 located at a side of an equatorial line adjacent to the shoulder land part row 7 at the axially inner side and these slant grooves 13 are opened to the circumferential main groove located adjacent to the second inner land part row 8 of the axially inner side.

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.
