Galaxy BP Premium tyre 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 miles. All R 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 enable repairs to be made closer to the tyre bead, eliminating the need for a separate sidewall repair unit. These repairs are also designed to have excellent air retention when used in tubeless tyres. See charts to determine proper repair for size of injury.
