    摘要: To provide a pneumatic tire capable of improving wet performance without sacrificing steering stability. Since a pair of central circumferential main grooves 14 and a pair of side circumferential main grooves 16 are arranged on a tread 12, a fundamentally high level of wet performance can be obtained. Since a plurality of central land portion row lateral grooves 20 is formed at both sides of a central land portion row 18 to be spaced away from each other substantially at a constant distance, wet performance is further enhanced. Further, since central land portion row chamfer portions 24 are formed at obtuse angle portions of the central land portion row 18, the central land portion row chamfer portions 24 drain water between a tread surface and a ground-contact surface into the respective central circumferential main grooves 14 adjacent thereto, whereby wet draining performance is enhanced. Since drainage is conducted by the central land portion row chamfer portions 24, use of lots of the central land portion row lateral grooves 20 becomes unnecessary, thus making it possible to secure land portion rigidity of the central land portion row 18, and steering stability as well.
