There are times when you need to deflate your bike tire for several reasons such as :

  • Over-inflation
  • Changing an inner tube
  • Changing a tire
  • Packing the bike for travels
  • Puncture repair

Here are the step-by-step instructions on how to do it.

Tools required

  • Inner tube
  • Bicycle tire
  • Bicycle wheel

Estimated time

  • 30 seconds

1. Remove the valve cap

  • Place it somewhere safe so that you don’t lose it.
  • Skip this step if you don’t have one.

2. Loosen the small lockring nut on the valve core

  • Make sure to completely unscrew it.
  • Skip this step if you’re using a Schrader valve.

3. Release the air

  • For Presta valves (also known as French valves), gently depress the locking nut. Each press should only last for 0.5 to 1 second.
  • For Schrader valves (also known as American valves), gently depress the tiny pin in the middle of the valve for 0.5 to 1 second each time. You can use your fingernails to do it, but a flat-head screwdriver will definitely make things easier.
  • Pinch the tire with your fingers to determine if you have reached your desired tire pressure.
  • If you’re releasing all the air, then press and hold.
  • Repeat several times if necessary.

4. Once done, tighten the locking nut

  • Make sure to the nut is tightened all the way in.
  • Otherwise, you might accidentally release more air when you put on the valve cap.
  • Insert the valve cap and tighten it.

5. Insert the valve cap

  • Make sure its finger-tight so that it doesn’t rattle and drop off unknowingly.
