ABSTRACT:
A resilient tire that supports a load without internal air pressure includes a ground contacting tread portion and sidewall portions extending radially inward from said tread portion and anchored in bead portions. A bias ply carcass extends between the beads to support the sidewalls. A reinforced annular band is disposed radially inward of the tread portion. The band comprises an elastomeric shear layer at a radially outer side of the bias ply carcass and a membrane adhered to a radially outward side of the elastomeric shear layer. Each of the bias ply and membrane has a longitudinal tensile modulus sufficiently greater than the shear modulus of the shear layer so that when under load the ground contacting portion of the tire deforms to a flat contact region through shear strain in the shear layer while maintaining constant the length of the membranes.
