Yes, Run-Flat Tires Can Be Patched Run-flat tires, which work even after losing air pressure, give special repair considerations. Whether a run-flat tire can be patched or not depends mainly upon the type of damage that has occurred. You must think of it from several different angles:
Damage and Repairable Sections
Puncture Location:
Tire Tread Damage: If the puncture is in the tread, many manufacturers will allow for a traditional patch application assuming that it has not been run underinflated15LKJ.
Tyre sidewall damage: Tyres are not safe to repair if they have cuts on the tyre’s sidewall, this part of the tyre carries a lot of weight and stress25.
Extent of Use After Puncture:
Expecting to continue to drive on a run-flat tire after it has lost air can result in internal damage even if there is no outward appearance of the same. It is therefore important to determine if the tire was driven while it has been deflated for too long before inspections and fixes are made34.
Manufacturer Guidelines
Repairability standards for run-flat tires depend upon the manufacturer. Brands could have exclusion clauses preventing any repairs if there is cause for concern that driving on a flat tyre has caused internal damage26 Be sure to check the manufacturers specifications before proceeding with any repairs.
Safety Considerations
Fixing a run-flat tire comes with potential dangers. If a tire is damaged, it can suddenly fail resulting in unsafe driving conditions. Consequently, Inspection has to be extremely careful and the repair56 adherent safety protocols must follow
All in all, run-flat tires can be patched sometimes depending on the type and location of damage, how far they were driven flat for and manufacturer specific recommendations. Safety first, arrivederci and when in doubt consult a professional.
