ABSTRACT:
The run-flat tire of this invention includes a pair of bead regions, a crown region with a tread and a tread reinforcing package including a cap ply and self supporting sidewalls between each bead region and the crown region. An innerliner ply maintains air within the inflated tire. The self supporting sidewalls each include a first crescent-shaped reinforcing member, an inner carcass layer, an inner sidewall supporting complex and an outer sidewall and bead protecting complex. The supporting sidewalls effectively have a plurality of crescent-shaped reinforcing members and a plurality of carcass layers. The sidewall supporting complexes are realized by providing first and second partial carcass layers along with a filler rubber portion and a second crescent-shaped reinforcing member, which can be formed by a separate tire building operation. The sidewall protecting complexes can be formed in a similar operation. The run-flat tire of this invention can be realized within standard production rates for building tires. The inflated vs. deflated performance tradeoffs in ride comfort, handling, radial stiffness and endurance of the tire are substantially maintained with improved mass and rolling resistance over previous run-flat tires. This is accomplished with a run-flat tire having relatively small weight increases over a standard tire and with a rim that can be used interchangeably with the standard tire.
