The instant invention is directed to a method for producing reinforcement for cast tires and a method for the production of reinforced cast tires having bead rings, from castable elastomers, the tire inside the mold being restricted by a core during the formation, characterized in that before the toroidal tire core is installed into the mold, the reinforcement and the bead rings are applied thereto. First, the two bead wires are enclosed by a piece of cut fabric which is adapted to the size of the tire, the warp threads in the fabric running substantially perpendicular to the bead rings, then two sides of the fabric are joined, such that the jointure seam runs substantially parallel to the weft direction, as a result of which, both bead wires are connected via the piece of fabric. When the fabric has been pushed together to at least half the circumference of the bead rings, the two rings are positioned on either side of the tire core and the piece of fabric is then drawn around the rings and over the complete core and joined together at its ends.
