Title: PNEUMATIC TIRE
Abstract:
To achieve both maneuverability and wet performance, this pneumatic tire 1 is provided with: a plurality of shoulder lug grooves 23 positioned farther outward in a tire width direction than an outermost major groove 12; and a thin groove 40 positioned farther outward in the tire width direction than the outermost major groove 12, formed spanning between adjacent shoulder lug grooves 23 in a tire circumference direction, and connected at both ends to the shoulder lug grooves 23. The thin groove 40 is formed astride a ground contact end T, a ground contact surface inner end part 42 positioned farther inward in the tire width direction than the ground contact end T is connected to a position in a shoulder lug groove 23 where a bottom-raised part 26 is formed, a ground contact surface outer end part 43 positioned farther outward in the tire width direction than the ground contact end T is connected to a position in a shoulder lug groove 23 where the bottom-raised part 26 is not formed, and the relationship between the distance W in the tire width direction between the ground contact surface inner end part 42 and the outermost major groove 12 and the groove depth D1 of the outermost major groove 12 is W ≥ (D1 × 0.8).
