TECH Permacures utilize a nylon-reinforced design along with TECH grey cushion gum which makes applying the Insert quick and easy while virtually eliminating cutting of the repair. The Permacure repair vulcanizes through the injury thus creating a permanent repair that will last the life of the tire in off road applications. When Permacures are used to repair on-road vehicles’ tubeless tires, this is a temporary repair and should be followed up with permanent repair applied from the inside of tire, using a qualified, professional repair facility.
