Pneumatic tire

A pneumatic tire, comprising:

• a first circumferential groove and a second circumferential groove on a tread surface of a tread portion, extending along a tire circumferential direction, and sandwiching a tire equatorial plane;
• and
• a land portion defined by the first circumferential groove and the second circumferential groove, the land portion being divided by a first plurality of lateral grooves which communicate with both the first circumferential groove and the second circumferential groove to form a block row, a second plurality of lateral grooves being formed in each block of the block row, the second plurality of lateral grooves consisting of:
• narrow grooves formed as a set of two narrow grooves provided intersecting the tire circumferential direction, communicating with the first circumferential groove, and terminating within the land portion;
• and
• an auxiliary groove provided intersecting the tire circumferential direction, communicating with the second circumferential groove, terminating within the land portion, a terminating end portion of one of the auxiliary grooves being disposed between terminating end portions of each of the sets of the narrow grooves in the tire circumferential direction.
