How to change an inner tube: a simple and practical guide

Knowing how to change an inner tube is an essential skill for any cyclist, whether beginner or experienced. A flat tire can happen anytime, and being able to fix it quickly can save you a lot of trouble. Here’s a step-by-step guide to changing an inner tube easily, whether you’re riding a road bike, gravel bike, or MTB.

Required equipment

Before starting, make sure you have the following items at hand:

• A spare inner tube suitable for your wheel size.
• Tire levers.
• A hand pump or CO2 cartridge.
• A wrench (if your wheels don’t have quick releases).
• Gloves (optional, to keep your hands clean).

Step 1: Remove the wheel

1. Loosen the brake: If you have rim brakes, open the brake lever to release the wheel.
2. Remove the wheel: Loosen the quick release lever or use a wrench to unscrew the wheel nut. For the rear wheel, shift to the lowest gear (smallest cog) before removing it.

Step 2: Remove the tire

1. Insert a tire lever: Slide a tire lever between the tire bead and the rim, then lift the edge of the tire.
2. Slide the lever: Run the lever around the wheel to remove one side of the tire from the rim. Use a second lever if needed.
3. Remove the inner tube: Gently pull out the damaged inner tube, starting at the valve.

Step 3: Check the tire and rim

Before installing a new inner tube, carefully inspect the inside of the tire and the rim:

• Find the cause of the puncture: Check for any debris, like glass or thorns, still stuck in the tire.
• Examine the rim tape: Ensure it’s in good condition and that no spokes or sharp edges could damage the new inner tube.

Step 4: Install the new inner tube

1. Pre-inflate the inner tube: Inflate it slightly to make installation easier and reduce the risk of pinching.
2. Insert the valve: Place the valve through the hole in the rim.
3. Fit the inner tube: Carefully tuck the inner tube into the tire, ensuring it isn’t twisted or pinched.

Step 5: Reinstall the tire

1. Replace the tire bead: Use your hands to work the tire bead back onto the rim. If needed, use a tire lever for the tougher sections.
2. Check the installation: Ensure the inner tube isn’t caught between the tire and rim.

Step 6: Inflate the tire

1. Pump up the tire: Use a pump or CO2 cartridge to inflate the tire to the recommended pressure (indicated on the tire sidewall).
2. Inspect the fit: Make sure the tire is properly seated and the pressure is even.

Step 7: Reinstall the wheel

1. Put the wheel back on: Position the wheel in the frame or fork, then tighten the quick release lever or nuts.
2. Reconnect the brake: Close the brake lever or adjust it as needed.

Tips to prevent flat tires

• Use reinforced tires: They offer better resistance to punctures.
• Check tire pressure regularly: Underinflated tires are more prone to punctures.
• Install tire liners: They protect the inner tube from sharp objects.
