Abstract
A method for building a run flat pneumatic tire by precoating a thin high strength annular band of material with a layer of rubber to form a rubber/band composite. The rubber coated band composite is at least partially cured and then assembled between a body ply carcass and a tread package in a usual second stage tire building machine. The band can be encased completely with the rubber or the rubber can be applied only to the outside surface, the inside surface or the end edges of the band or any combination thereof.
