Motorcycle Tubeless Tire Repair Information
Dunlop recommends only permanent repairs performed from the inside of the tire, using a combination patch/plug method. Never attempt a repair from the outside, or inject a sealant, or simply use an innertube, a patch or a plug as a substitute for a proper repair.
Only a qualified tire repair shop or motorcycle tire dealer should perform repairs. Inspection of the tire and adequacy of repair becomes the responsibility of the person actually performing the repair and Dunlop does not warrant the results of a repair in any way. Combination patch/plug repair kits for use by the repair shop or dealer are available with accompanying instructions from companies such as:
200 Paris Ave.
Northvale, NJ 07647
Technical Rubber Co.
P.O. Box 486
Johnstown, OH 43031
Tip-Top/Moto Combi Kit
Tech Uni-SealŪ Repair Kit (Also has been marketed by Honda, Kawasaki, and Yamaha with their own part numbers.)
NOTE: There may be suitable repair kits and materials provided by manufacturers other than those listed above.
Before any repair should be attempted, however, a tire must be removed from the wheel and thoroughly inspected. The following are minimum guidelines for the repairer:
Tires should not be repaired if any of the following conditions exist:
1. A tire has been previously injected with a sealant/balancer.
2. The puncture is larger than 6mm (1/4") in diameter.
3. The puncture is not perpendicular to the carcass.
4. The puncture is in the tire sidewall.
5. Separation of plies, tread separation, separation of any other components.
6. Cut or broken ply cords.
7. Broken or damaged bead wires.
8. Cut or damaged chafers (bead area).
9. Deterioration of the carcass inside the tire due to "run flat" or underinflation.
10. Cracks or other damage to the integrity of the inner liner.
11. Excessive wear - tire should have at least 1/32 of an inch of tread depth, excluding tread wear indicators.
12. Cracks in sidewall or tread.
13. Impact breaks, cuts, snags or gouges that penetrate the surface.
1. There should be no more than one repair in any quarter of the tire and no more than two repairs per tire.
2. The wheel itself must be in good condition. Any cracked or bent wheel, however slightly, may allow the loss of air and cause subsequent deflation of the tire.
3. Following repair, the valve assembly should be replaced and the tire/wheel rebalanced.
4. Speed should not exceed 50 mph for the first 24 hours after tire repair and the repaired tire should never be used at speeds over 80 mph. The repairer is solely responsible for instructing the motorcyclist as to the restrictions to be placed on tire use following repair.
In summary, NO form of temporary repair should be attempted. Motorcycle tire repairs leave no room for error and any doubt as to inspection or adequacy of repair should be resolved by discarding the tire.
