Patent attributes
A pneumatic tire includes shoulder lug grooves and narrow grooves. The shoulder lug grooves are positioned outward in a width direction with respect outermost main grooves. The narrow grooves are positioned outward in the width direction with respect to the outermost main grooves, are formed in spaces between the shoulder lug grooves that are adjacent to each other in the tire circumferential direction, and have both ends connected to the shoulder lug grooves. The narrow grooves are formed across the ground contact edges. A relationship W≥(D1×0.8) is satisfied, where W indicates a distance between the ground contact surface inner end portions and the outermost main grooves in the tire width direction and D1 indicates a groove depth of the outermost main grooves.
