Tire Plug Meaning in Cycling

A tire plug is a small, sticky strip of rubber used to fix a puncture in a tubeless bicycle tire. These are often called bacon strips because of their brown color and long, thin shape on the trail. When a hole is too large for the liquid sealant to close, the rider inserts a plug into the leak. The plug fills the gap and bonds with the tire rubber to create a permanent and airtight seal. For example, a mountain biker can fix a flat in less than a minute by using a plug tool without removing the wheel. This allows you to continue your ride quickly without the mess of installing a traditional inner tube. I recommend that every rider using a tubeless setup carries a small kit of tire plugs in their saddlebag. It is an incredibly satisfying and effective way to handle mechanical trouble while you are out in the woods. You simply push the plug in, pull the tool out, and pump the tire back up to pressure. It is a modern solution that has made flat tires much less of a headache for adventurous cyclists.
