How to troubleshoot a Punctured Bike Tyre
A punctured bike tyre is one of the most common cycling problems. This guide covers patching a tube or replacing it entirely.
Step-by-Step Fix
- Remove the wheel from the bike using quick-release or spanners.
- Deflate the tyre completely and remove the tyre from the rim using tyre levers.
- Pull out the inner tube and inflate it slightly to find the puncture.
- Mark the puncture location and roughen the area with sandpaper.
- Apply patch glue, wait for it to become tacky, and press the patch on firmly.
- If replacing the tube, insert the new tube into the tyre.
- Reinstall the tyre, ensuring the tube is not pinched, and inflate to the correct pressure.
