Abstract
A pneumatic tire according to the present embodiment includes a shoulder main groove that is disposed on one side in a width direction from a tire equatorial plane and extends in a tire circumferential direction, a shoulder land portion that is formed between a ground contact end and the shoulder main groove, and a plurality of slits that divide the shoulder land portion into a plurality of blocks in the tire circumferential direction. The shoulder main groove is formed of a zigzag groove in which an inward bent portion and an outward bent portion are alternately and repeatedly disposed, and angles of the slits with respect to the tire width direction are provided to be 10 degrees or less.

A pneumatic tire comprising:
- a shoulder main groove that is disposed on one side in a width direction from a tire equatorial plane and extends in a tire circumferential direction;
- a shoulder land portion that is formed between a ground contact end and the shoulder main groove;
- and
- slits that divide the shoulder land portion into blocks in the tire circumferential direction,
- wherein the shoulder main groove is formed of a zigzag groove in which each of inward bent portions and each of outward bent portions are alternately and repeatedly disposed,
- wherein the slits include first slits each connected to one of the inward bent portions, and second slits each connected to one of the outward bent portions,
- wherein an angle between one of the first slits and one of the second slits with respect to the tire width direction is 10 degrees or less,
- wherein the pneumatic tire comprises a central land portion that is formed on the other side of the shoulder main groove with respect to the shoulder land portion in the tire width direction;
- and inclined grooves that are provided in the central land portion at intervals in the tire circumferential direction,
- wherein each of the inclined grooves is a groove in which one end is open to the shoulder main groove and the other end terminates in the central land portion, and extends in a direction inclined to the tire circumferential direction, and is connected to one of the inward bent portions,
- wherein the pneumatic tire comprises sipes that are provided in the central land portion,
- wherein each of the sipes are provided along an imaginary extension line extending from one of the slits,
- wherein the sipes include first sipes each of which is provided along the imaginary extension line extending from one of the first slits and disposed on the other side of the one of the first slits with respect to the shoulder main groove in the tire width direction;
- and second sipes each of which is provided along the imaginary extension line extending from one of the second slits and disposed on the other side of the one of the second slits with respect to the shoulder main groove in the tire width direction,
- wherein each of the first sipes and each of the second sipes are alternately disposed in the tire circumferential direction, and
- wherein one side of each of the first sipes in the tire width direction is open to one of the inclined grooves.
