light truck, truck and tractor tyres. Plies = 2

Tech's BP Bias Ply repairs can be used on tubeless or tube-type tyres.  They offer excellent flexibility, greater strength, superior construction and have been proven safe and dependable by millions of on-the-road kilometres.  All Tech bias repairs are manufactured with a ply of rubber between the fabric and cushion gum which acts as a float or shock absorbing ply.  Repair unit construction allows for easy application and enables repairs to be made closer to the tyre bead, eliminating the need for a separate sidewall repair unit.  BP repairs are also designed to have excellent air retention when used in tubeless tyres.
