An averagetotal gauge (GC)of a center land portion located within a width of 10% of a width of a second widest belt in a belt layer on right and left sides of an equatorial plane in the width direction, an average thickness(SG) of a sound absorptive member inside the pneumatic tire and located within a range identical to that of the center land portion, and the elongation at break (EB) of the carcass cords satisfy 15≤GC/(GC+SG/10)×EB (%)≤25.

A pneumatic tire includes at least one carcass layer between bead portions on an inner side in a radial direction of sidewall portions on both sides of a tread portion extending in a circumferential direction and having an annular shape, and the carcass layer includes carcass cords formed of organic fiber cords obtained by intertwining a filament bundle of organic fibers. The carcass layer includes turn-up portions formed by being turned back at an end portion of the bead portions to an outer side in a tire width direction. The carcass cords have an elongation at break EB satisfying EB≥15%, a cap tread rubber compound of the tread portion has a 300% modulus MD satisfying 4 MPa≤MD≤13 MPa, and the elongation at break EB and the 300% modulus MD satisfy 600≤40×MD+20×EB (%)≤1300.

A tire (10) for a vehicle comprises a radially outermost working layer (41) which comprises at least one undulation (412) in line with a central rib (251) of the tread (2). The undulation (412) is radially on the outside of the points of the working layer (41) in line with the bottom face (243) of the circumferential groove (24) closest to the undulation (412) and has an amplitude of at least 1 mm. The undulation (412) is vertically in line above at least one local reinforcing layer (6) comprising reinforcing elements that are mutually parallel and make with the circumferential direction (XX′) of the tire an angle of which the absolute value is at most equal to 5°.

A pneumatic tire includes a tread portion 16, a sidewall portion 14, a buttress portion 18, and a hollow portion 50. A cross-sectional shape of a bottom surface of the hollow portion 50 is a curved shape in which a plurality of arcs having different radii of curvature are disposed in a tire radial direction and adjacent arcs are connected at a contact point C where the adjacent arcs have a common tangent line, or is a shape in which a plurality of arcs having different radii of curvature are connected by a straight line connecting contact points where the adjacent arcs have a common tangent line. An outside end 32a, in the tire radial direction, of a sidewall rubber 32 provided on the sidewall portion 14 is located on an outside Ro in the tire radial direction from the groove bottom 36B1 of the shoulder main groove 36B.

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 pneumatic tire includes lug grooves having alternating first and second groove portions. The first groove portion intersects an equator, extends in a width direction, and communicates with an adjacent second groove portion. The second groove portion inclines from the first groove portion at a smaller angle relative to a circumferential direction smaller than that of the first groove portion and extends to a tread edge on one side. The first groove portion is on a stepping side with respect to an end on the tread edge side. The second groove portions curve or bend and have an average angle in an inner region smaller than that of the second groove portions in an outer region. A maximum length in the width direction of center blocks defined by narrow grooves connecting adjacent second groove portions and the lug grooves is 25%-35% of a development width.

A tire includes a tread portion including a pair of shoulder main grooves and a crown region defined between the pair of the shoulder main grooves. The crown region includes a plurality of crown blocks. A ground contacting surface of at least one of the crown blocks is provided with a first sipe, a second sipe, and a third sipe. The first sipe, the second sipe, and the third sipe are connected with each other at one intersection.

Center land portions of a tire each include a circumferential narrow groove extending in a tire circumferential direction, and a first lateral groove opening to one edge portion of each of the center land portions at one end and connecting to the circumferential narrow groove at the other end, and a second lateral groove opening to the other edge portion of the center land portion at one end and connecting to the circumferential narrow groove at the other end. Further, the circumferential narrow groove has a zigzag shape formed by repeatedly connecting a first long portion, a first short portion, a second long portion, and a second short portion. Furthermore, the first lateral groove connects to the first long portion of the circumferential narrow groove having the zigzag shape, and the second lateral groove connects to the second long portion of the circumferential narrow groove having the zigzag shape.

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.
