ABSTRACT:
A pneumatic safety tire, of the type preferably having a section height of five inches or greater, having a pair of crescent shaped elastomeric reinforcing members located between the innerliner and side wall and extending from adjacent the tread shoulders to at least the apex of the bead fillers of the tire. A pair of bias reinforcing plies are located between the elastomeric reinforcing members and the side walls of the tire and extend along the side walls from adjacent the tread shoulders to below the top most turn-up ends of the body ply. The elastomeric reinforcing members preferably are similar in composition to that of the bead fillers and have a low hysteresis value preferably within the range of 0.03 and 0.11, a high modulus preferably within the range of 2600 psi and 2800 psi and a Shore A hardness preferably within the range of between 85 and 91. The elastomeric reinforcing members in combination with the reinforcing bias plies, enable a high section height tire to run at high speeds for a relatively long distance in an uninflated condition, and improve the performance of heretofore low section height run flat tires.
