Abstract

A pneumatic tire that can achieve good on-snow performance and good wear resistant properties at the same time. In a tread pattern (9), the ratio of the maximum length in the tire's circumferential direction of each block (81), which forms block rows (11, 12) in a tread center section (21), to the maximum width in the tire's lateral direction of the block (81) is set in the range of not less than 1.4 but not more than 1.9. The total groove area ratio of circumferential main grooves (6) in a ground contact surface and lateral grooves (7) also in the ground contact surface is set in the range of not more than 35%. The center groove area ratio of the tread center section (21) including circumferential main grooves (62) at the outermost positions in the lateral direction of the tire is set to be not less than three times the shoulder groove area ratio of tread shoulder sections (22).
