What is the purpose of car tire self-sealing fluid?
2 Answers
Car tire self-sealing fluid is used to quickly repair air leaks. This tire repair fluid is a mixture containing various high-molecular chemical materials, widely applicable to rubber tires of electric vehicles, motorcycles, and small to medium-sized cars. It is particularly effective for puncture holes with diameters of about 1 to 5 millimeters, making it an essential item to carry in your vehicle. The fluid works by using fibers mixed with rubber particles or fine suspended rubber in the adhesive. When a tire loses air, these rubber particles or fine rubber particles precipitate and form clumps to block the air holes. Based on this plugging principle, it is highly effective for holes, especially in tubeless tires, but less effective for cuts or slits.
Tire sealant is primarily used when your tire gets punctured by small objects like nails or glass shards. It automatically flows to seal the hole, preventing air leakage. This saves you the hassle of immediately changing the tire or waiting for a tow truck, allowing you to drive safely to a repair shop. As someone who frequently takes long highway trips, keeping a bottle in the car has been a lifesaver; it's especially useful for temporary minor punctures. Note that sealant only works on small holes—if the puncture is too large or irregular, it won't be effective. To use, simply inject it directly through the valve stem—it's quick and easy, but you should promptly check the tire interior afterward to prevent fluid buildup from affecting the tire pressure sensor. Overall, it's a practical tool for sudden tire issues, saving you time and money.
