How Long Can Tire Sealant Be Used After Adding to Tubeless Tires?
2 Answers
Tire sealant can be used for 3-6 months after adding to tubeless tires. Although tubeless tire sealant can serve as an emergency tire repair method with fast sealing time (usually solidifying within about 5 minutes after application), its repair effect is limited. It should only be used as a temporary solution and cannot serve as a long-term repair method. Tubeless tire sealant is a white foam-like liquid composed of synthetic polymer compounds, stored in compressed gas cans. During application, it is injected into the tire through the valve stem. Under the centrifugal force generated by vehicle movement, the sealant evenly coats the inner surface of the tire, forming a sealing film that provides puncture repair functionality. As a polymer compound, tubeless tire sealant has certain corrosive properties. Prolonged use may cause damage to both the tire and wheel rim. After using tire sealant, the tire interior may experience some corrosion, and a rubberized protective film forms on the inner surface layer. This may affect subsequent grinding and adhesion processes during permanent tire repairs, potentially making some punctures unrepairable.
Tire sealant is used for emergency sealing of small punctures and typically lasts from one to three months, depending on the tire material and driving conditions. I once had a friend who added sealant, and the tire lasted only two weeks before leaking again on the highway, which was very dangerous. It's advisable not to rely on it for too long. Ideally, visit a professional shop for a thorough inspection or repair within a week, as this is only a temporary solution. Over time, the sealant can dry out, lose effectiveness, or even affect tire balance. Regularly check tire pressure to ensure it stays within the normal range and avoid sudden emergencies.
