<p>Nail-Deflecting, Inner-Tube Assembly For Run-Flat Tires A pneumatic tire having a "run-flat" capability, is disclosed. The tire is in the form of a substantially toroidally shaped carcass having a pair of bead-reinforced sidewall regions and a crown region annularly bridging the sidewall regions. Internally of the carcass, there is provided an expandable nail-deflector for deflecting a nail that punctures, for example, the crown region. The nail deflector has a releasably constrained normal condition when the crown region is puncture-free that is annularly spaced from the interior of the crown region, and is circumferentially self-expandable into engagement with the interior of the crown region upon puncture of the latter by a nail to deflect such nail harmlessly away from its path of entry.</p> |
