Abstract
A pneumatic tire having an annular band is provided, the annular band for reinforcing a bead portion and a sidewall portion of the pneumatic tire. In one embodiment, the annular band comprises a plurality of filaments having a high extensional modulus of elasticity and a high tenacity bonded together in a matrix of resin. Further, the annular band is cured or formed with a cross-section which tapers from the tire's bead portion to the tire's sidewall portion. Preferably, the annular band may be cured or formed in situ during the curing of the tire in which it is placed. In another embodiment, a structural element having a high resistance to compression is bonded to and circumferentially within the annular band. In a third embodiment the structural element is wedge-shaped in cross-section.
