    Abstract: A pneumatic tire comprises: a carcass layer, a belt layer, and a tread rubber. The belt layer is formed by laminating a pair of cross belts having a belt angle of not less than 10° and not more than 45° in absolute terms and of mutually opposite signs, and a circumferential reinforcing layer having a belt angle within a range of ±5° with respect to the tire circumferential direction. A distance (Gcc) from a tread profile to a tire inner circumference surface along a tire equatorial plane, a distance (Gsh) from a tread end to the tire inner circumference surface, and a distance (Ge) from the tread profile to the tire inner circumference surface at an end portion on the outer side of the circumferential reinforcing layer in the tire width direction have relationships satisfying 1.10≤Gsh/Gcc and 1.00≤Ge/Gcc≤1.10.

    Abstract: 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.
