Can Self-Sealing Fluid Be Added to New Tubeless Tires?
2 Answers
New tubeless tires can have self-sealing fluid added, but generally, tubeless tires can only have the fluid added once. Characteristics of Tubeless Tires: Tubeless tires are pneumatic tires without an inner tube. These tires feature high elasticity and wear resistance, along with excellent traction and heat dissipation properties. The surface of a tubeless tire is made of high-quality rubber, which increases tension upon inflation, creating a certain pressure. Therefore, even if the tire is punctured, it doesn't lose air immediately like a conventional tire but can continue to support driving for a certain period. Precautions for Self-Sealing Fluid: Generally, tubeless tires can only have self-sealing fluid added once because the fluid is somewhat corrosive. While using self-sealing fluid for tubeless tire repair is convenient, it's necessary to prevent tire corrosion. Therefore, excessive use should be avoided as it can easily lead to tire damage.
Speaking of the issue of adding sealant to new tubeless tires, I think it's worth discussing. When I first bought my new car, I also considered whether to add some sealant just in case of a puncture. But later, I learned from a mechanic friend that new car tires are of high quality and generally not prone to leaks, so adding sealant might be unnecessary. That sealant stuff, once injected, flows inside the tire and over time can cause wheel imbalance, making the steering wheel feel shaky while driving. Moreover, new cars come with tire pressure monitoring sensors, and the chemicals in the sealant might corrode them or clog the valve stem, leading to expensive repairs and voiding the warranty. I've seen cases where the inner walls of the tires became sticky and messy after adding sealant, making cleanup a real hassle. As long as you maintain proper tire pressure and avoid bumps, there's really no need to add sealant to new tires. If something goes wrong, you can always use it later—keeping an emergency repair kit on hand is enough.
