Abstract
A pneumatic tire () provided in the tread portion () with a row (R) of crown blocks () divided by crown axial grooves (), two rows (R) of middle blocks () divided by middle axial grooves (), and two rows (R) of shoulder blocks () divided by shoulder axial grooves (), Each of the crown axial grooves () is circumferentially aligned with one of the middle axial grooves () such that the crown axial groove () is positioned within a middle-axial-groove range (Mc) defined between 1st and 2nd axial straight lines (Za and Zb) which are drawn passing through 1st and 2nd extreme circumferential end points (and) of the middle axial groove (), respectively. The circumferential length of the middle-axial-groove range (Mc) is not less than 25% but not more than 50% of a pitch length (P) defined between the two 1st extreme circumferential end points (and). The middle-axial-groove range (Mc) does not overlap with any of the shoulder axial grooves ().
