<p>A large size pneumatic tire for heavy vehicles comprises the combination of an annular bead seat having a lateral face terminating in a flange and an inner face with a toe portion and a heel portion meeting at a vertex and forming in radial cross section the shape of a very open V, and a bead reinforced with a bead wire so arranged that the median plane of the bead wire intersects the toe portion of the inner face at a distance from the vertex at least equal to one-tenth of the diameter of the cross section of the bead wire, the outer surface of the bead being thus in permanent contact with the lateral face and inner face of the bead seat.</p> |
