Pneumatic tire

A pneumatic tire comprising:

• first and second circumferential main grooves extending in a tire circumferential direction;
• and a pair of shoulder land portions and one row of a center land portion defined by the first and second circumferential main grooves,
• the center land portion comprising:
• a first inclined lug groove extending at an incline with respect to the tire circumferential direction and opening, at one end portion, to the first circumferential main groove and terminating, at another end portion, within the center land portion;
• a second inclined lug groove extending at an incline in a direction identical to a direction of the first inclined lug groove and opening, at one end portion, to the second circumferential main groove and terminating, at another end portion, within the center land portion;
• a first lateral groove connecting the first inclined lug groove with the second circumferential main groove;
• a second lateral groove connecting the second inclined lug groove and the first circumferential main groove;
• first and second auxiliary grooves connecting the first inclined lug groove with the second inclined lug groove adjacent to each other;
• and
• a plurality of center blocks defined by the grooves,
• a groove depth H1 of the first inclined lug groove over an entire region from an opening portion to the first circumferential main groove to a terminating end portion within the center land portion having a relationship with a maximum groove depth Hg of the first circumferential main groove represented by 0.80≤H1/Hg≤1.00, and
• a maximum groove depth H2 of the first lateral groove having a relationship with a groove depth H1e at the terminating end portion of the first inclined lug groove represented by 0.70≤H2/H1e≤0.90.
