Abstract:
A structurally supported resilient tire comprising a ground contacting tread portion, sidewall portions extending radially inward from said tread portion and anchored in bead portions adapted to remain secure to a wheel during rolling of the tire, and,a reinforced annular band disposed radially inward of said tread portion, wherein said band comprising an elastomeric shear layer, at least a first membrane adhered to the radially inward extent of said elastomeric shear layer and at least a second membrane adhered to the radially outward extent of said elastomeric shear layer, and wherein a ratio of the longitudinal tensile modulus of one of said membranes to the shear modulus of said shear layer is at least 100:1 such that deforming said ground contacting tread portion by an externally applied load from substantially a circular shape to a flat shape maintains a substantially constant length of said membranes and relative displacement of said membranes occurs substantially by shear strain in said shear layer.
