Pneumatic tire

A pneumatic tire, comprising:

• a plurality of main grooves extending in a tire circumferential direction, and a plurality of land portions that are partitioned by the plurality of main grooves, wherein the plurality of land portions include at least one shoulder land portion arranged outwardmost in a tire width direction;
• each of the at least one shoulder land portion comprises a plurality of width grooves of groove width not less than 2 mm;
• wherein the plurality of width grooves comprise a first width groove and a second width groove;
• wherein the first width groove extends as far as an outside end in the tire width direction of the at least one shoulder land portion and comprises, at a location toward the exterior in the tire width direction from a contact patch end, a wide portion at which groove width increases toward the outside end in the tire width direction;
• wherein the second width groove extends as far as the outside end in the tire width direction of the at least one shoulder land portion and comprises a constant width without a wide portion at which groove width increases toward the outside end in the tire width direction;
• wherein all of the first ends of the first and second width grooves terminate within an interior of the at least one shoulder land portion such as not to connect to any of the plurality of main grooves;
• the plurality of width grooves further comprise a third width groove, and the third width groove comprises a constant width without a wide portion at which groove width increases toward the inside end in the tire width direction;
• the first width groove and the third width groove are arranged to have a portion thereof mutually overlapping as viewed in the tire width direction;
• the third width groove is arranged toward the interior in the tire width direction from the first width groove;
• the first width groove is entirely separated from the third width groove;
• the second width groove is separated from the first width groove in the tire circumferential direction;
• the at least one shoulder land portion further comprises at least one sipe of groove width less than 2 mm, wherein the at least one sipe extends from one of the plurality of main grooves to the contact patch end such that the at least one sipe is arranged along a full breadth of the at least one shoulder land portion in the tire width direction;
• and
• the at least one sipe is arranged between the first width groove and the second width groove in the tire circumferential direction.
