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.
