Abstract
A tire includes a central region configured to be mounted to a wheel and a crown region including a circumferential tread and a shear element disposed below the circumferential tread. The shear element includes an upper reinforcement layer, a lower reinforcement layer, and an elastic region disposed between the upper reinforcement layer and the lower reinforcement layer. A radial distance between the upper reinforcement layer and the lower reinforcement layer varies along an axial width of the tire. The tire also includes an intermediate region extending from the central region to the crown region.
Claims15
A tire comprising:
- a central region configured to be mounted to a wheel;
- a crown region including a circumferential tread and a shear element disposed below the circumferential tread;
- wherein the shear element includes an upper reinforcement layer that includes a plurality of upper rings that are layered in an axial direction of the tire, a lower reinforcement layer that includes a plurality of lower rings that are layered in an axial direction of the tire, and an elastic region disposed between the upper reinforcement layer and the lower reinforcement layer, and
- wherein a radial distance between the upper reinforcement layer and the lower reinforcement layer varies along an axial width of the tire;
- and
- an intermediate region extending from the central region to the crown region.
A tire comprising:
- a central region configured to be mounted to a wheel,
- a crown region including a circumferential tread, a plurality of lower rings that are layered in an axial direction of the tire, and a plurality of upper rings that are layered in the axial direction of the tire,
- wherein at least one of the plurality of lower rings and the plurality of upper rings has rings with different diameters, and
- an intermediate region extending from the central region to the crown region.
A tire comprising:
- a central region configured to be mounted to a wheel;
- a crown region including a shear element disposed below a circumferential tread, the shear element having a radial thickness that varies along an axial width of the tire, the shear element including a plurality of lower rings that are layered in an axial direction of the tire and a plurality of upper rings that are layered in the axial direction of the tire;
- and
- an intermediate region extending from the central region to the crown region.
