How Long Can Tire Sealant Last?
2 Answers
Tire sealant can last for 2 years. The principle of tire sealant for puncture repair: A liquid containing short fiber materials or fine particles is pre-injected into the tire in a specific amount. When tiny holes appear in the tire, they will be blocked; when a puncture occurs, the escaping air will carry the liquid with fibers or particles out. The amount of tire sealant to be added is evaluated based on the tire size. Remove the valve core and completely deflate the tire. For existing sealant in the tire, ensure the valve is facing downward during deflation. Before use, invert the sealant bottle and shake it vigorously to mix evenly. Remove the sleeve from the sealant bottle, cut open the outlet, attach the sleeve, connect the sealant and sleeve to the valve, and squeeze the recommended amount of sealant into the tire.
I've personally experienced tire sealant's duration many times. Generally, it lasts about 6 months to a year, provided the tire is in good condition without serious damage. When I was younger driving trucks for long-haul transport, I used it extensively - the liquid gradually dries out, especially prone to failure in hot weather. If frequently driving on rough roads or with underinflated tires, the sealant's effectiveness may shorten to just a few months. I recommend checking tires every three months to verify the liquid remains moist, replacing when necessary. This isn't a permanent solution, only for emergencies - prolonged use leaves residue inside tires that's troublesome to clean. Overall, safety comes first - don't delay repairs too long, since blowouts can disrupt journeys.
