Abstract:
Provided is a pneumatic tire with a tread pattern that includes two first circumferential main grooves, shoulder land portions, shoulder lug grooves, shoulder sipes, and narrow circumferential grooves, the shoulder lug grooves being closed off midway in the region of the shoulder land portions without connecting with the first circumferential main grooves and including first regions and second regions that are disposed in the regions closer to the first circumferential main grooves than the first regions and have a groove depth that is less than that of the first regions. The shoulder sipes are connected with the second regions and extend toward the first circumferential main grooves. The narrow circumferential grooves extend in the tire circumferential direction and have a groove width that is less than the groove width of the shoulder lug grooves. The narrow circumferential grooves intersect with the second regions of the shoulder lug grooves.
