Provided is a tire including, in a tread surface, a plurality of land portions partitioned by a circumferential main groove extending continuously in a tire circumferential direction, on at least one side in a tire width direction, and comprising, in an internal land portion located in a vehicle-installed inside half portion to a tire equatorial plane among the plurality of land portions, an internal resonator including a first auxiliary groove that terminates in the internal land portion, and a first branch groove that communicates between the first auxiliary groove and the circumferential main groove, and in the first branch groove, a hidden groove having an opening width in the tread surface that is smaller than a groove width of a groove bottom is provided adjacent to the first auxiliary groove.

A tire tread includes a plurality of circumferential grooves, each of the plurality extending continuously in a tire circumferential direction. The plurality of circumferential grooves define a circumferentially extending shoulder rib. The shoulder rib has a plurality of shoulder elements. Each shoulder element is defined by two lateral shoulder grooves. Each shoulder element has an axially outer shoulder element and a corresponding axially adjacent and axially inner shoulder element separated by a circumferential groove. The axially outer shoulder elements each have a pair of angled outer lateral S-shaped blind grooves extending axially away from the inner shoulder elements.

A tire for vehicle wheels comprises a tread band (2), on which a first circumferential rib (14) is formed, on which a plurality of first notches (20) are formed, which extend as a whole over at least 80% of the width of the first circumferential rib and each of which comprises: ⋅ i. a first portion (21) which is substantially rectilinear and has a first inclination with respect to a circumferential direction, ⋅ ii. a second portion (22) which is substantially rectilinear and has a second inclination with respect to the circumferential direction having a sign opposite to said first inclination, and ⋅ iii. a connecting portion (23) that extends between said first portion and said second portion; respective pluralities of the second and the third notches (30; 40), which are blind and substantially parallel to the first (21) and the second portion (22), respectively, of said first notches (20), are further formed on the first circumferential rib (14).

In the pneumatic tire, the ratio TW/SW of the ground contact width TW of the tire and the maximum width SW of the tire is 0.75 to 0.95. The tire width direction outside end of the belt layer extends in the tire circumferential direction and is positioned outside in the tire width direction than the circumferential direction groove formed most outside in the tire width direction. A width direction sipe extending in the tire width direction and closest to the tire circumferential direction end portion of the block and a width direction sipe adjacent to the width direction sipe and extending in the tire width direction are formed in the block, and a distance from the tire circumferential direction end portion to the width direction sipe along the tire circumferential direction is longer than a distance from the width direction sipe to the width direction sipe along the tire circumferential direction.

Provided is a pneumatic tire including: a plurality of main grooves each having a zigzag shape and extending in a tire circumferential direction; and a land portion defined by the main grooves adjacent to each other and having a rib structure that is continuous with the tire circumferential direction. The land portion includes first and second lug grooves having a semi-closed structure. A maximum length L21 of the first lug groove in a tire width direction has the relationship 1.30≤L21/L22≤2.30 with respect to a maximum length L22 of the second lug groove.

The tire can have a tread portion. The tread portion can include a first shoulder circumferential groove and a first shoulder land portion. In the first shoulder land portion, a plurality of first shoulder lateral grooves can be disposed. At least one of the first shoulder lateral grooves can include an inner end connected to the first shoulder circumferential groove, a maximum groove width portion, and an outer portion.
