The purpose of the present invention is to provide a pneumatic tire that exhibits excellent operating stability whether the road surface is a dry road surface, a snow covered road surface or a wet road surface. A block pitch length (Po) of an outside block column (22) is greater than a block pitch length (Pi) of an inside block column (24). The tire width direction size in a region sandwiched between two circumferential grooves becomes smaller in the order of ribs (20), the outside block column (22), and the inside block column (24). Inclined grooves (16a) partitioning and forming the ribs (20) are opened only on a circumferential groove (12b) on a vehicle mount inside region partitioning and forming the ribs (20). |
