Pneumatic tire

A pneumatic tire comprising:

• an annular tread portion extending in a tire circumferential direction;
• a pair of sidewall portions disposed on both sides of the tread portion;
• and
• a pair of bead portions disposed inward of the sidewall portions in a tire radial direction,
• the tread portion being provided with four main grooves including a pair of outer main grooves and a pair of inner main grooves that extend in the tire circumferential direction, the main grooves defining a center land portion, a pair of intermediate land portions located outward of the center land portion, and a pair of shoulder land portions located outward of the intermediate land portions, wherein
• the center land portion, the intermediate land portions, and the shoulder land portions each are provided with a plurality of sipes arranged at intervals in the tire circumferential direction, the sipes in the center land portion each have a widened portion formed with a wide groove width at one end, the sipes in the shoulder land portions each extend from an outer side of a ground contact end in a tire lateral direction toward the outer main groove, orientation of the sipes in the center land portion and the shoulder land portions with respect to the tire circumferential direction is opposite to orientation of the sipes in the intermediate land portions, an inclination angle θCE of the sipes in the center land portion with respect to the tire circumferential direction, an inclination angle θMD of the sipes in the intermediate land portions with respect to the tire circumferential direction, and an inclination angle θSH of the sipes in the shoulder land portion with respect to the tire circumferential direction satisfy a relationship θCE<θMD<θSH<90°, and
• an end of each sipe in the intermediate land portions on the side of the inner main grooves is disposed between ends of adjacent sipes in the center land portion in the tire circumferential direction, and at any position on an entire circumference of the tire, at least one of a sipe among the sipes in the center land portion or a sipe among the sipes in the intermediate land portions is present on a tire meridian.
