Abstract of the Disclosure TIRE TREAD BELT AND METHOD OF MAKING An annular tire tread belt 12 is assembled of uncured resilient material having reinforcing cords 16 and 18. An annular container 10 of resilient material has reinforcing cords extending between annular bead rings at the edges. The container is shaped in a toroidal configuration and the tread belt 12 stuck to the container by a layer of suitable tacky barrier material 26 with sufficient tack to maintain the tread belt in a centered position on the container for engagement with a centered portion of the mold. The barrier material also is sufficiently incompatible with the materials of the container and tread belt to prevent appreciable chemical bonding across the interface during curing of the tread belt. After at least partial curing of the tread belt, the tread belt is detached from the container and is ready for use in a tire.
