Is the Tire Ruined After Using Tire Sealant?
2 Answers
Using tire sealant will not ruin the tire, but it may cause some corrosion to the wheel rim and tire. Tire sealant is convenient and quick, eliminating the need to remove or replace the spare tire. Simply inject the sealant into the tire through the valve stem to seal the leak. However, tire sealant can affect the tire's dynamic balance. After using it, avoid driving at high speeds, and vehicles with tire pressure monitoring systems (TPMS) should use it sparingly to prevent damage to the TPMS. Tire sealant cannot repair sidewall damage, as a damaged sidewall indicates that the internal cords have broken, posing a safety hazard. In such cases, the tire should be replaced immediately. Due to its corrosive nature, tire sealant should only be used as an emergency solution. Prolonged use may increase future maintenance costs. If time and conditions permit, proper tire repair methods should be applied promptly.
As someone who works with tires year-round, I've seen too many tires treated with tire sealant. To be blunt, it's fine for short-term emergencies, but long-term use really damages the tire. The chemicals in the sealant can corrode both the wheel rims and the rubber, especially the metal valve stems which are most prone to oxidation. Just last week, a Model Y had a valve stem corroded to the point of leaking, with the entire wheel rim discolored. So after using sealant, you must go to a professional shop for thorough cleaning as soon as possible. If left untreated for over three months, the tire is basically ruined.
