Abstract

A pneumatic safety tire 10 capable of being used in the uninflated condition at a speed up to a maximum predetermined value for a maximum predetermined distance which can then be repaired and returned to normal service, comprises sidewalls 14, 16 which have a configuration such that the bending moment stresses experienced in the sidewall when the tire is operated in the uninflated state do not exceed a predetermined value. The portion 46,48 of the sidewall radially and axially inward of the carcass ply structure 30 is made of an elastomeric material having a dynamic modulus at least equal to or greater than 50 kg/cm<2> and has a ratio of hysteresis to dynamic modulus less than or equal to 24% kg/cm<2>. <IMAGE>
