In a tire, an inclination angle of a cord included in a second belt layer with respect to a tire width direction is defined as a positive inclination angle in a tire see-through plan view, an intersection point between a perpendicular line drawn from an end portion of a belt layer having a maximum belt width in the tire width direction to a carcass and a cord of an outermost carcass layer in a tire radial direction is defined as a first reference point in a tire meridian cross-sectional view, and an inclination angle of the cord with respect to the tire width direction at the first reference point is −3° or more in the tire see-through plan view.

A carcass layer of a pneumatic lire includes carcass cords of organic fiber cords obtained by intertw ining a filament bundle of organic fibers, and includes turn-up portions formed by turning back end portions of the carcass layer at bead portions toward an outer side in a width direction. The carcass cords have an elongation at break (EB) satisfying EB≥15%. 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 for heavy duty having an aspect ratio of 65% or less includes a carcass and a belt layer. A tread portion includes circumferential grooves. The circumferential grooves include a pair of shoulder circumferential grooves and a crown circumferential groove. The crown circumferential groove 11 is a narrow groove and each of the shoulder circumferential grooves is a wide groove. The belt layer includes metal belt cords inclined with respect to a tire circumferential direction. The belt layer has outer ends each positioned outside a respective one of the shoulder circumferential grooves in a tire axial direction. A belt half width is 55% or more and 85% or less of a carcass half width.

A pneumatic tire includes a pair of bead portions each having a respective bead core therein, a carcass extending between the bead portions and including a carcass ply that includes a main portion extending between the bead cores and a pair of turn-up portions turned up around the bead cores, and a pair of bead reinforcing layers being disposed outward in the tire axial direction of the turn-up portions so as to cover outermost ends in a tire radial direction of the turn-up portions. An outer surface of at least one of the bead portions is provided with a recess row including a plurality of recesses spaced in a tire circumferential direction, and in the at least one of the bead portions, an outermost end of the bead reinforcing layer is located outwardly in the tire radial direction of outermost ends of the plurality of recesses.

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 pneumatic tire comprises: a bead portion provided with an inside bead apex rubber disposed between a turned up portion and a main portion of a carcass ply, and an outside bead apex rubber disposed axially outside the turned up portion and having a radially outer edge; and a the sidewall portion provided with a sidewall reinforcing cord layer disposed axially outside the carcass and having a radially inner edge which is spaced apart from the radially outer edge of the outside bead apex rubber by a radial distance of not less than 5% of a tire section height.

Provided is a pneumatic tire. A partial tie rubber layer is selectively disposed between a carcass layer and an inner liner layer in an area on a tread portion on either side in a tire lateral direction excluding a center region of the tread portion such that a length of intrusion from a perpendicular line extending from an outermost edge of a belt layer in a tire lateral direction through the inner liner layer toward a tire equator of each of the partial tie rubber layers is within the range from 0 to 15 mm and a length of protrusion from the perpendicular line toward a bead portion of the partial tie rubber layer is within the range from 15 to 120 mm.
