How Long Can a Plugged Tubeless Tire Last?
2 Answers
3-5 months. A plugged tubeless tire can typically last for 3-5 months, and if repaired well, it may last one or two years. After that, the damaged area might start leaking again, requiring re-repair or direct replacement. Plugging a tire essentially involves using an awl to insert a glue-coated rubber strip directly into the tire puncture to seal the leak. Below is relevant information: Maintain specified tire pressure: Tubeless tires are made of high-quality rubber, offering good elasticity and flexibility, with a wide tolerance for pressure variations. Even at high pressure, they don't feel as stiff as conventional tires, so a pressure gauge must be used for checks. Unlike standard tires, tubeless tires won't naturally lose air unless punctured. Therefore, always use a pressure gauge to check and maintain the specified pressure during inflation, rather than relying on feel as with conventional tires. Avoid punctures: When using tubeless tires, avoid punctures from sharp objects and contact with acids or alkalis. Contamination by oils can also accelerate rubber degradation. Keep the tires clean to prevent rubber aging and extend their service life.
How long a tire plug lasts in a tubeless tire really depends on how you use and maintain it. I've been tinkering with cars since I was young, and over thirty years, I've done this quite a bit. A plug is just a temporary fix for a tubeless tire—if the puncture is small and in the center of the tread, a properly inserted plug can last about one to two years. But remember, drive gently—no hard acceleration or high-speed runs, as that can loosen the plug. The last one I fixed lasted a year and a half before leaking, and that was with suburban driving. You also need to regularly check tire pressure and the plug's position, as temperature changes in winter can accelerate aging. If the sidewall is damaged, a plug won’t help at all—you’ll need a new tire for safety. Overall, this isn’t a permanent solution; I’d recommend using it for no more than six months before getting a professional internal patch to avoid risks on the road.
