Abstract

A pneumatic tire which can be operated in a deflated condition without damage to the tire, wherein the tire has a cord ply, a tread, a ply with wire cords in the crown, and thick sidewalls wherein the cord ply extends from the heel of the bead to a location closely adjacent to the outer surface of the midpoint of the sidewall and thence towards the inner surface of the crown. The interior portion of the sidewall rubber has a high dynamic modulus with low hysteresis properties and high aging properties.
