An agricultural tire includes a toroidal tire structure containing vulcanized rubber in an amount of about 90 percent or more by weight. The tire structure may have one or more performance enhancing features, including high strength plies. The high strength plies contain cords that are formed of yarns, including polyamide yarns, and have individual cord tensile strengths within a range of about 400 N to about 700 N. The performance enhancing features further include circumferential belt plies having cords at angles of about 74 degrees or more from an axial direction.

A method to provide technology for suppressing, in a tire including a spiral cord layer and an auxiliary belt layer, the occurrence of separation between the spiral cord layer and the auxiliary belt layer. The tire includes: a carcass toroidally extending between a pair of bead portions; a spiral cord layer arranged on an outer side in a tire radial direction of a crown portion of the carcass and in which an upper layer and a lower layer are formed by spirally winding a reinforcing cord; and an auxiliary belt layer arranged on the outer side in the tire radial direction of the spiral cord layer. At least at ends in a tire width direction of a region where the spiral cord layer and the auxiliary belt layer are laminated, a rubber gauge between the spiral cord layer and the auxiliary belt layer is 0.5 mm to 14.0 mm.

A pneumatic vehicle tire has a carcass, a belt and a profiled tread. The belt includes four belt plies wherein the third belt ply and the fourth belt ply are working plies. The reinforcement members of the working plies are arranged at an angle to the circumferential direction of 10 to 45 and the reinforcement members of the fourth belt ply at an angle of 10 to 45. The reinforcement members of the third and fourth belt plies are arranged such that they cross one another. The reinforcement members of the first belt ply are arranged at an angle of 40 to 75 and the reinforcement members of the second belt ply are arranged at an angle of 0 to 5 to the circumferential direction. The reinforcement members of the third belt ply and the reinforcement members of the first belt ply have the same direction of inclination.

A tire comprises two working crown layers of reinforcing elements and, in each shoulder, an end of a layer of parallel reinforcing elements oriented circumferentially, said end being axially outside the working crown layers. The reinforcing elements have a diameter less than 1 mm and comprise threads with a diameter strictly greater than 0.16 mm, and, in a radial plane, the ratio between the thicknesses of rubber compound between the inner surface of the tire cavity and that point of a metal reinforcing element of the carcass reinforcement that is closest to said inner surface of the cavity, of the two parts of the tire profile that are centered on the respective orthogonal projections onto the inner surface of the tire cavity of the axially outer ends of said additional layers, and of the parts of the tire profile that have the smallest thicknesses, being greater than 1.15.

A crown reinforcement formed of at least two working crown layers of reinforcing elements. The tire additionally comprises, in each shoulder, at least one end of a layer of reinforcing elements that are mutually parallel in the layer and are oriented circumferentially, said end being axially outside said at least two working crown layers, the reinforcing elements of the carcass reinforcement having a diameter less than 0.85 mm, and said reinforcing elements of the carcass reinforcement being made up of threads with a diameter less than 0.16 mm.

A heavy-duty pneumatic tire includes an inclined belt in which reinforcing elements of a first belt layer and reinforcing elements of a second belt layer extend at an inclination angle of 5 to 30 relative to the tire circumferential direction in such a manner that the reinforcing elements of the first belt layer cross the reinforcing elements of the second belt layer. The shortest distance d between the reinforcing elements of the first belt layer and the reinforcing elements of the second belt layer is 0.64 mm or less. The outer edge of a carcass folded-up portion in the tire radial direction is located further inward in the tire radial direction than the tire maximum width position.

Provided is a pneumatic tire. Both terminals of a carcass layer are overlapped with each other in a tread region. The carcass layer has a triple layer structure including an inner layer positioned most inward in a tire radial direction in the tread region, an outer layer positioned most outward in the tire radial direction in the tread region, and an intermediate layer positioned between the inner layer and the outer layer in the tread region. A cord angle in the carcass layer in a tread central region with respect to a tire circumferential direction differs in at least one of the inner layer, the outer layer, and the intermediate layer from a cord angle in the carcass layer in a side region with respect to the tire circumferential direction.

A motorcycle tire comprises a carcass and a tread reinforcing layer. The tread reinforcing layer comprises a belt and a band. The band is composed of a jointless band ply having a developed width less than 65% of the developed tread width. The belt is composed of at least one belt ply having a developed width of 65% or more of the developed tread width. At first positions, the intersecting angle between the belt cords and the carcass cords is 20 to 60 degrees. In the tread portion in a tire meridional cross sectional view, a single arc passing through a point on the tread surface at the tire equator and two points on the tread surface at the tread edges has a radius of not more than 0.7 times the maximum tire cross-section width.

Provided is a tire comprising a pair of bead cores 5, a carcass 6, and a plurality of belt layers, wherein the plurality of belt layers comprise a first belt layer 7 with cords extending along the tire circumferential direction CD, and a second belt layer 8 with cords extending at an angle to the tire circumferential direction CD, which is arranged on the outer side in the tire radial direction than the circumferential belt layer, a communication device having a linear antenna is embedded at a tire radial position, that is inner side in the tire radial direction than a tire maximum width position and outer side in the tire radial direction than an outer edge position of the bead core 5 in the tire radial direction, and the linear antenna of the communication device is arranged along the tire circumferential direction.

The invention is directed to a pneumatic vehicle tire having a carcass and a belt built up on the radial outside of the carcass. The tire includes a profiled tread which is built up on the belt on the radial outside of the belt. The belt is formed from at least four belt plies which are arranged one on top of the other from the radial inside to the radial outside. The first belt ply and the second belt ply are crossing working plies. The reinforcing elements of the first and second belt plies are arranged at an angle of 10 to 45 to the circumferential direction. The reinforcing elements of the fourth belt ply are arranged at an angle of 40 to 75 to the circumferential direction and the reinforcing elements of the third belt ply are arranged at an angle of 0 to 5 to the circumferential direction.
