Is Self-Sealing Fluid Harmful to Car Tires?

[DeVivienne]

Self-sealing fluid is harmful to car tires. After using tire sealant, the tire surface will be corroded, and the formation of a colloidal protective film on the tire surface can affect the grinding and adhesion during the tire repair process, making subsequent repairs more difficult and potentially impossible. Self-sealing fluid is injected between the tire and the rim, utilizing the fluid's mobility to fill gaps when the tire is damaged, achieving a leak-sealing effect. Tires are a crucial component of a car, directly related to driving stability and safety, as they are the part of the car that contacts the ground. Tires are rubber products, and prolonged use can lead to wear and aging, necessitating regular replacement.

I've been driving for several years and have used tire sealant to fix punctures, but I've realized it has potential hazards. For example, the chemical composition can corrode the inside of the wheel rims, causing metal parts to rust and damage; the residue hardens inside the tire and clogs the valve, affecting the Tire Pressure Monitoring System (TPMS), leading to inaccurate error reports from the system; it also causes tire imbalance, resulting in body shaking and instability at high speeds, increasing driving risks. That time I used it as an emergency on the highway, and when I later went to the repair shop, the mechanic said the sticky residue was hard to clean and the rim was ruined, needing replacement. So, it's only suitable for temporary repair of small holes, after which you must clean the tire as soon as possible and seek professional repair. Don't rely on it for long-term convenience, or it will shorten the tire's lifespan by tens of thousands of kilometers and pose significant safety risks. Safety first, regular tire checks are key.

As a regular commuter, I've personally experienced the pros and cons of tire sealants. That time when my tire got punctured by a nail on my way to work, using the sealant did stop the leak, saving me time and effort. However, a few months later, I noticed rust and corrosion on the wheel rim edges, and hardened residue inside the tire causing driving vibrations, severely affecting ride comfort. When I took it for maintenance, the technician said the chemical components in the sealant can erode rubber and metal, especially accelerating damage during rainy or hot weather. The harm is significant and could increase accident risks! Now I only use it as a last-resort solution; I recommend carrying a portable repair kit or a spare tire for regular use. Don't let small savings cause major damage to your car.

I'm in the car enthusiast circle and have tried using tire sealant for small punctures—it's incredibly convenient. However, the downsides are obvious: the chemical liquid corrodes and rusts the rims; it worsens wheel balance, causing wobbling at high speeds; and it clogs sensors, affecting tire pressure readings. This temporary fix requires prompt cleaning afterward and shouldn't be treated as a permanent solution.
