Abstract: Disclosed is a pneumatic run-flat tire. The tire has at least one carcass reinforcing ply, at least one pair of sidewall wedge inserts, and a belt reinforcing structure. The belt reinforcing structure is formed from at least a pair of cross cord belt reinforcing plies. Located radially outward of the carcass reinforcing ply is a porous elastomeric layer. The porous elastomeric layer has a porosity level of 20 to 80%, preferably 40-70%, of the total volume of the porous elastomeric layer.

Abstract: A self-supporting pneumatic tire, capable of continued operation during under-inflation conditions, has at least one insert located in each tire sidewall. Forming the interior surface of the self-supporting tire is a stiffening layer of material having characteristics similar to that of the insert. In the tread region of the tire, and radially inward of the innermost carcass layer, and possibly in the interior bead region of the tire, is a partial inner liner layer of the bromobutyl rubber.
