What are the pros and cons of applying glue to tubeless tires?

The advantage of applying glue to tubeless tires is that it can quickly seal air leaks. Typically, after using tubeless tire sealant, it solidifies in about 5 minutes. However, the downside is that excessive use of glue can corrode the wheel rims, and it cannot repair large punctures, has poor effectiveness on cracks, and is ineffective for repairing sidewall perforations. There are various methods for repairing tubeless tires, with the most convenient and quickest being the use of sealant, which involves applying glue to tubeless tires. The sealant can quickly seal air leaks but is somewhat corrosive and is generally only applied once. If the tire is damaged again and leaks air, it is recommended to use more professional repair methods or replace the tire if necessary. When using tubeless tire sealant, it is injected into the tire through the valve stem. As the car moves, the centrifugal force causes the sealant to evenly coat the inside of the tire, forming a sealing film on the inner surface to achieve the repair effect.
I've been using sealant in tubeless tires for over a decade, and there are many benefits! It quickly seals small punctures, like when you get a nail in your tire—just inject the sealant, and it plugs the hole, allowing you to drive to the repair shop without the hassle of changing a spare tire on the roadside. However, there are downsides too: once the sealant dries, it can corrode the inside of the tire and the rim, shortening the tire's lifespan. Uneven application can also cause tire imbalance, leading to vibrations and unstable driving, which affects safety. This method is only a temporary fix and shouldn't be relied on too much—you should go to a professional shop afterward for a thorough cleaning and proper repair. I recommend regularly checking tire pressure and wear to prevent issues and reduce the need for emergency sealant use. In the long run, sealant is efficient for emergencies, but proper maintenance is what saves you time and money.
Pros and cons of using sealant in tubeless tires, analyzed from a technical perspective. Its biggest advantage is instant puncture sealing, functioning like self-healing coatings to prevent roadside blowouts—ideal for long-distance road trippers. However, drawbacks are significant: sealants may contain corrosive chemicals that degrade tire structure over time; improper injection causes imbalance, leading to wobbling and accelerated tread wear with increased fuel consumption. Economically, while sealants are cheap for emergencies, post-use residue removal is laborious, potentially raising repair costs. Alternatives include premium self-sealing tires or investing in portable inflation tools. Safety first—reserve for emergencies only, avoiding reckless overuse due to laziness.
