ABSTRACT:
A banded radial run-flat tire having a band with a dual-modulus of bending deflection behavior. Bands producing various basic dual-modulus characteristics are disclosed. In one type, the band has a greater resistance to bending forces tending to decrease its local radius of curvature than to those tending to flatten it. In a second type, bending stiffness increases with increasing stress irrespective of the bending direction. In a third type, a two-step modulus is demonstrated in which deflection is initially resisted at one rate and final deflection is resisted at a higher rate. Various embodiments of the band are disclosed in which the various types of dual-modulus behavior are obtained either by mechanical structural means or by internal geometry means.
