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.
