Tire

A tire comprising a tread portion which is located at an outer end portion in a tire radial direction and includes a tread surface portion facing an outer side in the tire radial direction,

• wherein two outer main grooves extending continuously in a tire circumferential direction are formed in an outer tread surface portion of the tread surface portion located on an outer side of a vehicle in a tire width direction with respect to a tire equator,
• two inner main grooves extending continuously in the tire circumferential direction are formed in an inner tread surface portion of the tread surface portion located on an inner side of the vehicle in the tire width direction with respect to the tire equator,
• a central land portion partitioned by the outer main groove and the inner main groove adjacent to each other in the tire width direction extends continuously in the tire circumferential direction,
• a plurality of outer resonators are formed in an outer land portion, which is partitioned by the two outer main grooves, and arranged in the tire circumferential direction, and a plurality of inner resonators are formed in an inner land portion, which is partitioned by the two inner main grooves, and arranged in the tire circumferential direction,
• the outer resonator includes
• a first vertical groove which extends in the tire circumferential direction, and
• a first branch groove and a second branch groove which have an inner volume smaller than that of the first vertical groove, extend in the tire width direction from both end portions of the first vertical groove in the tire circumferential direction such that the first branch groove and the second branch groove extend in directions opposite to each other, and are respectively opened to the two outer main grooves, and
• the inner resonator includes
• a second vertical groove which extends in the tire circumferential direction, and
• a third branch groove and a fourth branch groove which have an inner volume smaller than that of the second vertical groove, extend in the tire width direction from the second vertical groove such that the third branch groove and the fourth branch groove extend in directions opposite to each other, and are respectively opened to the two inner main grooves.
