A flat spot-proof tire, and a vehicle. The flat spot-proof tire comprises a tread, a cap ply, a belt ply and a carcass. The rubber hardness of the tread is 68-78 Shore A. The cap ply is formed by nylon cords having linear density of 90-140 pieces per 100 mm. The belt ply is formed by steel cords, which comprise HT steel wires and/or SHT steel wires. The carcass is formed by polyester cords having linear density of 100-120 pieces per 100 mm. The flat spot-proof tire and the vehicle use suitable industrial rubber and polyester fiber material, have a specific size design and undergo an optimized inflation process after vulcanization such that the long-term flat spot effects of the tire can be mitigated, and the jitter of the vehicle during high-speed traveling can be reduced.

A pneumatic tire 1 comprises a carcass 6 extending between bead cores of bead portions via a tread portion 2 and sidewall portions, and a belt layer 7 arranged on an outer side in a tire radial direction of the carcass 6 and inside of the tread portion 2. The pneumatic tire 1 further comprises a damping rubber body 30 arranged between the carcass 6 and the belt layer 7, and a noise damper 20 arranged on an inner cavity surface of the tread portion 2. A width W1 in a tire axial direction of the damping rubber body 30 is in a range of from 60% to 130% of a width W2 in the tire axial direction of the belt layer 7, and a water absorption rate of the noise damper 20 is in a range of from 10% to 25%.

Motorcycles tyre including a carcass structure, a zero-degree belt structure arranged in a radially outer position with respect to the carcass structure and a tread band arranged in a radially outer position with respect to the belt structure. The belt structure includes at least one hybrid reinforcing cord that has an elongation greater than 4% when subjected to a load equal to about 50 N and a tangent modulus with a monotonic progression as the elongation increases for elongations comprised between 4% and at least 9%.

The pneumatic tire includes a carcass layer, a belt layer disposed outward of the carcass layer in the tire radial direction, and a tread rubber disposed outward of the belt layer in the tire radial direction. Moreover, the belt layer is formed by laminating a pair of cross belts having a belt angle with an absolute value from 10 to 45 both inclusive and mutually opposite signs, and the circumferential reinforcing layer having a belt angle within a range of 5 relative to the tire circumferential direction. Moreover, the distance (Gcc) from the tread profile to the tire inner circumferential surface along the tire equatorial plane and the distance (Gsh) from the tread edge to the tire inner circumferential surface have a relationship satisfying 1.10Gsh/Gcc.

A cord of a band of a tire has a single-stranded structure in which steel filaments are stranded, and the number of the filaments is not less than three and not greater than six. In a cross-section of the cord, when represents a diameter of a smallest circle that surrounds cross-sections of the filaments, and represents a diameter of each filament, a gap is formed between the filaments such that the diameter is not less than three times the diameter and not greater than six times the diameter in the case of the number of the filaments being three or four. An initial elongation of the cord is not less than 0.1% and not greater than 1.5%.

A pneumatic tire (1), wherein an inter-cord distance (Gcl) between a circumferential reinforcing layer (145) and an inner-side belt ply (142) at a tire equatorial plane (CL), an inter-cord distance (Gcu) between the circumferential reinforcing layer (145) and an outer-side belt ply (143) at the tire equatorial plane (CL), an inter-cord distance (Gsl) between the circumferential reinforcing layer (145) and the inner-side belt ply (142) at end regions of the circumferential reinforcing layer (145), an inter-cord distance (Gsu) between the circumferential reinforcing layer (145) and the outer-side belt ply (143) at the end regions of the circumferential reinforcing layer (145) have a relationship such that 1.20(Gcl+Gcu)/(Gsl+Gsu)9.20.

A tire is provided with a carcass that is formed so as to include a carcass ply that extends from one bead portion to another bead portion; a belt that is disposed at a tire radial direction outer side of the carcass, and that is formed by one sheet of belt ply in which plural cords that are disposed with an inclination of not more than 10 relative to a tire circumferential direction and extend around an entire tire circumference in the tire circumferential direction are coated with a rubber having a tensile modulus of elasticity in excess of 50 MPa, one end portion in a longitudinal direction of the cords being positioned at one end side in a width direction of the belt ply, and another end portion in the longitudinal direction of the cords being positioned at another end side in the width direction of the belt ply; and a tread that is disposed at a tire radial direction outer side of the belt.

A tire is provided having a body ply that is displaced from the conventional equilibrium curve along the shoulder and upper side wall region of the tire in a manner that provides more uniform inflation growth along the crown region so as to reduce differences in rigidity between the center and shoulders of the tire, reduce load sensitivity, and/or decrease the propensity for cracking. A method for designing or constructing such a tire is also provided.

A tire includes: a tread portion including a tread surface; a pair of sidewall portions that extend inward in a tire radial direction from both sides of the tread portion in a tire width direction; and a pair of bead portions each of which includes a bead core that is elongated continuously to an inside of the sidewall portion in the tire radial direction and extends continuously in an annular shape in a tire circumferential direction, and a bead filler disposed adjacent to the bead core and outside the bead core in the tire radial direction. A density of the reinforcing cords changes in a range from 20% inclusive to 60% inclusive of a tire sectional height from a tire inner end in the tire radial direction, and such that an outside of an area, in which the density changes, has a low density of the reinforcing cords.
