The assembly of a large size pneumatic tire for a heavy off the road vehicle and an annular bead seat for a bead of the tire is characterized by the fact that said annular bead seat has a lateral face terminating in a flange and an inner face with a heel portion adjacent said lateral face and a toe portion meeting at a vertex and forming in radial cross section the shape of a very open V open toward said bead, and said bead has a reinforcing 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 the inner face of the annular bead seat and the assembly being slidably mountable on a wheel of the vehicle. |
