How to fix a flat bike tire

Get Started:

1. Remove the wheel with the flat tire. Open the brake, flip the bike over and use the quick release to remove the wheel.

2. Remove the damaged tube. Start by releasing any remaining air in the tube. Use one tire lever to get under the bead of the tire. Move a few inches to the side and insert the second tire lever. Slide the second tire lever around the rim until the tire is completely over the rim. Remove damaged tube.

3. Check for the source of damaged tube. Inflate the damaged tube and listen and feel for the damaged spot. Use the valve stem for reference and check the inside of the tire to make sure any debris or cause of the flat is removed. Then carefully check the tire for any other potential problems.

4. Insert new tube. Begin by unraveling the new tube. Blow it up a little to give it the shape of the tube. Place the valve stem in first then use your hands to place the rest of the tube into the tire. Use your hands to roll the bead of the tire back into the rim. Use a tire lever if needed.

5. Blow the tire up to the correct pressure. Be sure the bead of the tire stays within the rim.

6. Replace the wheel. Line up the wheel with the dropouts on the bike. If it's the rear wheel carefully put the chain and derailleur into place. Once the wheel is completely in the dropouts tighten the quick release. Flip the bike over and reconnect the brakes.

7. Final evaluation. Make sure the tire is centered and that the brakes are working properly. Then you're good to go.
