<p>The run-flat tire of this invention includes thickened sidewall portions, a belt package with a cap ply, lower sidewall rubber support portions, a specially designed bead seat area with a rim seat ply and three carcass layers. The classical problems of inflated vs. deflated performance tradeoffs in ride comfort, handling, radial stiffness and endurance of the tire are substantially improved. This is accomplished with a run-flat tire having relatively small weight increases over a standard tire and a rim that can be used interchangeably with the standard tire.</p><p>The run-flat tire system of this invention is capable of maximum lateral accelerations under nominal operations of approximately 0.90gs and extended operating efficiency (i.e., handling and durability) at higher speeds for longer distances.</p> |
