What Is Tire Sealant and How Does It Work for Bicycle Tubes?

According to CyclingTips, tire sealants can be particularly effective for tubeless setups, but they are also used in traditional inner tubes for added protection against punctures and flats. These sealants can significantly increase the longevity of tires in various conditions, making them a popular choice among cyclists.

Key aspects of tire sealants include their ability to seal punctures instantly as they occur, usually within a diameter of 1/4 inch. The sealant coats the inside of the tire, and when a puncture happens, the air escaping from the tire forces the sealant to fill the hole.
