Abstract
A tire (10) is provided with a cast body (12). The cast body has an annular circumferentially extending isotropic portion (14) having a pair of anisotropic side portions (16,18) extending therefrom. The side portions are rendered anisotropic by geometric means. A reinforcing means (30) is attached to the inner or interior surface of the side portions and extends from the isotropic portion to a point radially inwardly of the maximum section width (SW) of the tire. The reinforcing means may include a number of alternating ridges and grooves (46,48). The body may be cast from an elastomeric material such as polyurethane. A tread (26) and belt package (28) is disposed over the body and may be either elastomeric or rubber.
