    Abstract: [Problem to be Solved] To provide an airless tire that allows both good drainage performance and good durability to be achieved and allows uneven wear resistance to be improved. [Solution] An airless tire 1 is provided that includes a cylindrical tread ring 2 that has a ground contact surface 5. Multiple through holes 8 and a reinforcing body 11 are provided in the tread ring 2, the multiple through holes 8 penetrating the tread ring 2 in a thickness direction of the tread ring 2. The multiple through holes 8 are arranged at intervals along a tire circumferential direction. The reinforcing body 11 includes a first reinforcing body 12 that extends in the tire circumferential direction in regions between adjacent through holes 8. Both ends (12e) of the first reinforcing body 12 in the tire circumferential direction terminate without being exposed from inner peripheral surfaces of the through holes 8.

    Abstract: [Problem to be solved] To provide an airless tire that has a small rolling resistance.
    [Solution] An airless tire 1 is provided that includes a cylindrical tread ring 2 that has a ground contact surface (2a). The tread ring 2 has therein a reinforcing body 6. The reinforcing body 6 includes an annular first reinforcing cord layer 7 that extends in a tire circumferential direction, an annular second reinforcing cord layer 8 that is arranged on a tire radial direction inner side of the first reinforcing cord layer 7 and extends in the tire circumferential direction, and a shear layer 9 that is formed of an elastomer and is arranged between the first reinforcing cord layer 7 and the second reinforcing cord layer 8. The shear layer 9 includes a first portion 10 and a second portion 11, a loss tangent (tanδ) and a shear modulus (Ee) (unit: MPa) of the first portion 10 at a temperature of 30 °C satisfying the following Equations (1) and (2), and the second portion 11 being formed of a material different from the first portion 10. tanδ ≦ 0.06 Ee / tanδ ≧ 1500

    Abstract: A tire is disclosed having a path of thermal conductivity within a cast polyurethane component of the tire which extends from an internal portion of the tire to the tire's outer sidewall surface. The cast polyurethane component contains a dispersion of boron nitride particles. Preferably, the cast polyurethane is a reaction product of a liquid polyurethane reaction mixture comprising an organic polyisocyanate and polymeric polyol, or a primary aliphatic polyamine, desirably a diamine, and isocyanate terminated pre-polymer of an organic polyisocyanate and polymeric polyol, wherein said polymeric polyol is a saturated hydrocarbon polyol comprising at least one of polyester polyol and polyether polyol, and wherein the cast polyurethane does not contain carbon-to-carbon unsaturation. The boron nitride particles are preferably layered hexagonally crystalline boron nitride (h-BN) particles.
