A pneumatic tire having improved wet performances is disclosed, which comprises a tread of a rib type pattern divided into three or more ribs by at least two circumferential grooves so that the tread defines both side regions and the remaining central region by a pair of the circumferential grooves arranged close to both side ends of the tread and is provided at each region with sipes. In this type of the tire, each of the sipes arranged on both side regions is inclined at a small angle with respect to the transverse line of the tire and each of the sipes arranged on the remaining central region is inclined at a small angle with respect to the circumferential line of the tire. |
