Zusammenfassung:	The invention particularly relates to a reinforcing cord for elastomeric objects, which cord is built up of two or more groups of endless filament bundles which are twisted or laid together. Each group contains at least one bundle of PPDT filaments and at least one bundle of rayon filaments. The cord is especially meant for use in pneumatic tires of vehicles. When use is made of the cord composite according to the invention, radial ply tires for trucks need be provided with only two carcass plies and heavy-duty tires of passenger cars need comprise only one carcass ply.
