Abstract

A radial ply pneumatic tire is described. The tire has a carcass with a bead portion, a carcass reinforcing structure, and a bead filler. The carcass reinforcing structure has two plies with turnup ends wrapped about each bead. The turnup end of the first ply terminates in radial proximity of the maximum section width of the tire. In a preferred embodiment of the invention, the tire carcass includes elastomeric first and second fillers the first filler being located between the first ply and the innerliner of the tire, and the second filler being located between the first and second ply. The fillers stiffen the sidewalls to permit the tire to be driven while uninflated. The bead core of the preferred embodiment has a flat base and a first and second surface extending from the base and inclined relative to the base thereby forming acute included angles of .alpha. and .beta. whereby a is greater than or equal to .beta.. The tire may further include an aramid overlay radially outwardly of the reinforcing belt.
