Abstract
A non-pneumatic tire includes an inner ring having an axis of rotation and an outer ring coaxial with the inner ring. The non-pneumatic tire further includes support structure extending from the inner ring to the outer ring and a circumferential tread extending about the outer ring. The circumferential tread includes a shear element. The shear element includes a lower shim layer of solid material, an upper shim layer of solid material, and an elastic layer disposed between the lower shim layer and the upper shim layer. The elastic layer has a higher elasticity than the lower shim layer and the upper shim layer.
