A pneumatic tire with a tread portion provided with a tread pattern, the pneumatic tire comprising:
- a center main groove provided on a tire equator line and extending in a tire circumferential direction,
- a first inclined lug groove group including a plurality of first inclined lug grooves provided at intervals in the tire circumferential direction, each one of the first inclined lug grooves being provided on a first side of the center main groove in a tire lateral direction and extending, at any position in a ground contact region of the tread portion, from the center main groove in an inclination direction inclined with respect to the tire circumferential direction and the tire lateral direction while facing outward on the first side in the tire lateral direction and also facing in a first direction of the tire circumferential direction,
- a second inclined lug groove group including a plurality of second inclined lug grooves provided at intervals in the tire circumferential direction, each one of the second inclined lug grooves being provided on a second side of the center main groove in the tire lateral direction and extending, at any position in the ground contact region of the tread portion, from the center main groove in an inclination direction inclined with respect to the tire circumferential direction and the tire lateral direction while facing outward on the second side in the tire lateral direction and also facing in the first direction of the tire circumferential direction, and
- an inner branched lug groove group including inner branched lug grooves each provided for a corresponding one of the first inclined lug grooves and the second inclined lug grooves, each one of the inner branched lug grooves being branched from a middle of one of the first inclined lug grooves and the second inclined lug grooves and extending inward in the tire lateral direction while being inclined, with respect to the tire circumferential direction and the tire lateral direction, in an inclination direction identical to an inclination direction of the first inclined lug grooves or the second inclined lug grooves, each one of the inner branched lug grooves being connected to the center main groove without being connected to an adjacent first inclined lug groove or an adjacent second inclined lug groove adjacent to one of the first inclined lug grooves or one of the second inclined lug grooves in the first direction, wherein
- each one of the first inclined lug grooves and the second inclined lug grooves includes a center portion extending outward from the center main groove in the tire lateral direction in a linear or curved shape, an outer portion extending inward from a shoulder side of the tread portion in the tire lateral direction in a linear or curved shape, and a bent portion at which the center portion and the outer portion are bent and connected together, and
- the center portion is smaller in groove depth than the outer portion.
