Bias-Ply repair units are designed for use in punctures, reinforcing or section repairs and can be applied in any repairable area of a tube or tubeless bias-ply tire. The reinforcing plies are protected and encased in a molded “ply package” making the repair unit strong while remaining flexible. The face stock used in the repair units will vulcanize either chemically or in a low temperature (precure) system when applied with vulcanizing cement. This repair unit is black with gray vulcanizing gum on a blue poly backing.
