Most motorcycle tyre manufacturers do not recommend plugging a tire, that said it is a safety concern. As Don stated we have done it to get home, and yes the ( mushroom) plug patch if done correctly on MOST tires can be a permanent repair, It is your ride you decide

TYRE REPAIR
Some punctures in motorcycle tyres may be repaired. Dunlop recommends only permanent patch/plug repairs of small (maximum 1/4-inch diameter) tread area punctures from within the dismounted tyre by a qualified tyre repair shop or motorcycle dealer. Never perform an exterior repair and never use an inner tube as a substitute for a proper repair.
Speed should not exceed 80kph (50mph) for the first 24 hours after repair, and the repaired tyre should never be used at speeds higher than 120kph (75mph). Check inflation pressure after tyre cools for at least three hours following run-in, or sooner if air loss is suspected.
No form of temporary repair should be attempted because secondary damage caused by a penetrating object may not be detected and tyre or tube deflation may occur at a later date.
Dunlop does not recommend the use of liquid sealants. These are a form of temporary repair, and may adversely affect ply material and mask secondary damage caused by a penetrating object.
Reliance upon sealants can result in sudden tyre failure and accident.
DUNLOP MOTORCYCLE TUBELESS TYRE REPAIR INFORMATION
Dunlop recommends only permanent repairs performed from the inside of the tyre, using a combination patch/plug method. Never attempt a repair from the outside, or inject a sealant, or simply use an inner tube, patch or plug as a substitute for a proper repair.
Only a qualified tyre repair shop or motorcycle tyre dealer should perform repairs. Inspection of the tyre 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.
Before any repair is attempted, a tyre must be removed from the wheel and thoroughly inspected. The following are minimum guidelines for the repairer. Tyres should not be repaired if any of the following conditions exist:
- a tyre has been previously injected with a sealant/balancer
- the puncture is larger than 6mm (1/4-inch) in diameter
- the puncture is not perpendicular to the carcass
- the puncture is in the tyre sidewall
- separation of plies, tread separation, separation of any other components
- cut or broken ply cords
- broken or damaged bead wires
- cut or damaged chafers (bead area)
- deterioration of the carcass inside the tyre due to “run flat” or under-inflation
- cracks or other damage to the integrity of the inner liner * excessive wear – tyre should have at least 1/32 of an inch of tread depth, excluding tread wear indicators
- cracks in sidewall or tread
- impact breaks, cuts, snags or gouges that penetrate the surface
Please note:
- There should be no more than one repair per tyre
- The wheel itself must be in good condition. A cracked or bent wheel may lead to loss of air and cause subsequent deflation of the tyre
- Following repair, the valve assembly should be replaced and the tyre/wheel rebalanced
- Speed should not exceed 80kph (50mph) for the first 24 hours after tyre repair and the repaired tyre should never be used at speeds higher than 120kph (75mph)
- The repairer is solely responsible for instructing the motorcyclist as to the restrictions to be placed on tyre use following repair. In summary, no form of temporary repair should be attempted. Motorcycle tyre repairs leave no room for error and any doubt as to inspection or adequacy of repair should be resolved by discarding the tyre
Be sure to consult our Motorcycle Tyre Limited Warranty, Care and Maintenance brochure for additional information regarding the use of Dunlop tyres. Seek a qualified motorcycle tyre repair centre for more details. Never attempt to repair a damaged tyre without the assistance of an experienced tyre mechanic.
