<p>The invention relates to a bracing ply comprising reinforcing elements, which are made of steel cords, for a vehicle pneumatic tire, in particular, for a pneumatic tire used on transporters or light trucks and reinforced pneumatic tires. Said bracing ply is provided with two steel cord plies (bracing plies) which are stacked in a radial direction, whereby the radially inner steel cord ply is wider in the axial direction of the tire than the radially outer steel cord ply. In addition, the individual steel cords of a ply run diagonally with a slope ranging from 18° to 25° with regard to the zenithal plane of the tire. The radially inner and the radially outer steel cord plies have opposed slopes, are comprised of individual filaments with a filament diameter of 0.32 mm, and are provided with a U+T structure (untwisted+twisted), whereby the radial distance between steel cord plies is smaller in the zenithal plane of the tire than in the shoulder areas.</p> |
