Abstract
A pneumatic radial ply passenger tire ( ) having a tread ( ), a casing with two sidewalls ( ), two radial plies ( ) extending from and wrapped about two annular beads ( ) and a belt reinforcement structure ( ) located radially between the tread and the plies. Inner ply ( ) is reinforced with essentially inextensible metal cords and is designed to carry a compressive load during runflat operation. Outer ply ( ) is reinforced with organic-fiber cords designed to withstand tensile stresses during runflat operation. A circumferentially deployed insert ( ) is disposed between the inner and outer radial plies ( ) in each sidewall ( ) adjacent to the shoulder of the tread. The metal cords ( ) of inner ply ( ) have compressive-load-hearing capacity which reduces the mass of the insert material ( ). The metal cords ( ) also have thermal conductivity properties that dissipate heat buildup from both ply ( ) and insert ( ).
