A pneumatic tire is provided with a belt in which reinforcing cords are embedded in resin. A graph shows proportional belt chamfer height BWH values on a horizontal axis X and proportional tread chamfer height TWH values on a vertical axis Y. The proportional tread chamfer height TWH and proportional belt chamfer height BWH are specified so as to fall in a region of this graph that is bounded by a straight line expressed by the formula Y=−2.43X+17.9. This region is at the side of the straight line at which the proportional tread chamfer height TWH and proportional belt chamfer height BWH are smaller.

Agricultural vehicle tire having tread (1) with bearing surface (10) on which main lugs (3) and shorter secondary lugs (3) are formed on each side of the equatorial mid-plane (XX′), each secondary lug (3) interposed between two main lugs (2). The main lugs (2) and secondary lugs (3) make up, in the radial direction, a lens (21, 31) of a first material, each lens (21, 31) surmounted by a second material extending to the contact face of the main lugs and the secondary lugs. The viscous modulus G″1 of the first material is at most 60% of the viscous modulus G″2 of the second material. The complex modulus G*1 of the first material differs from the complex modulus G*2 of the second material, the difference between these complex moduli being at most 30% of the complex modulus G*2 of the second material.

A pneumatic tire including: a pair of bead cores; a carcass that is formed spanning the pair of bead cores; a belt layer that is disposed at a tire radial direction outside of the carcass and that is formed by covering a cord with a thermoplastic resin having an elastic modulus of from 100 MPa to 10,000 MPa and winding the cord around a tire circumferential direction; and a tread that is provided at a tire radial direction outside of the belt layer. A thickness of the pneumatic tire at a tire equatorial plane is no greater than 5 mm.

A tire includes a spiral belt layer and ring-shaped bands. The spiral belt layer is provided at the outer periphery side of a tire carcass member and is formed by a resin-coated cord wound in a helical shape. The bands are disposed at the tire diameter direction outer side of each of an end portion of the spiral belt layer at one side in the tire width direction and an end portion at the other side. Each band includes a belt-shaped member that is wound at least one full circumference in the tire circumference direction. The band is provided with an overlap portion that is specified with a larger number of layers of the belt-shaped member than other regions of the band in the circumference direction. The overlap portion is disposed at a circumference direction position that does not correspond with length direction end portions of the resin-coated cord.

Agricultural vehicle tire having tread (1) with bearing surface (10) on which main lugs (3) and shorter secondary lugs (3) are formed on each side of the equatorial mid-plane (XX′), each secondary lug (3) interposed between two main lugs (2). The main lugs (2) and secondary lugs (3) make up, in the radial direction, a lens (21, 31) of a first material, each lens (21, 31) surmounted by a second material extending to the contact face of the main lugs and the secondary lugs. The viscous modulus G′1 of the first material is at most 60% of the viscous modulus G′2 of the second material. The complex modulus G′1 of the first material differs from the complex modulus G′2 of the second material, the difference between these complex moduli being at most 30% of the complex modulus G′2 of the second material.

A run-flat tire includes a reinforcing rubber layer with a roughly crescent-shaped meridian cross-section disposed in sidewall portions at both sides in a tire width direction. The tread portion is provided formed of a tread rubber that includes a cap tread rubber and an undertread rubber disposed on an inner side of the cap tread rubber in a tire radial direction and having a higher hardness than the cap tread rubber. In a meridian cross-section, a gauge of the undertread rubber on a shoulder land portion on an outer side of an outermost main groove located furthest outward in the tire width direction is thicker than a gauge of the undertread rubber of a center land portion closest to a tire equatorial plane.

In a pneumatic tire, a partial tie rubber layer is disposed between a carcass layer and an innerliner layer in a limited manner across an entire region excluding end portions near a pair of bead portions; end surfaces on both sides in a tire lateral direction of the partial tie rubber layer are inclined surfaces that form an acute angle with respect to a surface of the partial tie rubber layer on the carcass layer side; and an inclination angle of the inclined surfaces with respect to the surface of the partial tie rubber layer on the carcass layer side is from 20 to 60.

A metal-resin composite member for a tire, comprising plural metal cords that are positioned alongside each other, an adhesive layer that is disposed on the metal cords, and a resin layer that is disposed on the adhesive layer, the metal-resin composite member satisfying at least one of the following (1) or (2): (1) the adhesive layer is independently disposed on each of the plural metal cords, and at least one of the adhesive layers has a cross-sectional shape that has a projecting portion; (2) the adhesive layer is integrally disposed on all of the plural metal cords, and a region consisting of the metal cords and the adhesive layer has a cross-sectional shape that has, between the metal cords, a portion that is narrower in width than a portion at which the metal cords are disposed.

Tire comprising a crown reinforcement formed of two working crown layers having unequal axial widths, layer C of rubber compound between ends of the working crown layers, layer S of polymer compound in contact with at least one working crown layer and in contact with the carcass reinforcement and the crown reinforcement comprising a layer of circumferential reinforcing elements arranged radially between two working crown layers. Distance d between the end of the axially narrowest working layer and the working layer separated from the axially narrowest working layer by the layer C is 1.1<d<2.2, being the diameter of the reinforcing elements of the layer of circumferential reinforcing elements, in a meridian plane. The thickness of layer C is substantially constant and the complex dynamic shear modulus G*, measured at 10% and 60 C. on the return cycle, of layer S is greater than 1.35 MPa.

A tire 2 includes a reinforcing layer 20 located between a tread 4 and a carcass 12. The reinforcing layer 20 includes a band 38 and a belt 40. The band 38 includes a full band 42 and a pair of edge bands 44. The full band 42 has an end 42e located axially outward of a shoulder circumferential groove 28s. The belt 40 includes a third belt ply 46C located radially inward of the pair of edge bands 44.
