Slime tire sealant is a product that is designed to seal punctures in tires. It is made of a thick, gooey substance that is inserted into the tire through the valve stem. When a puncture occurs, the Slime sealant leaks out and fills the hole, sealing it so that air does not escape.
Slime tire sealant does work on bike tires, and can be an effective way to repair punctures. However, it is not a permanent fix and will need to be reapplied periodically. Additionally, it is important to note that Slime will not work on large holes or tears in the tire. In these cases, the tire will need to be replaced.
