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
This article covers the steps to deflate a bike tire.
Tools required :
- Inner tube
- Bicycle tire
- Bicycle wheel
Estimated time : 30 seconds
Step-by-step instructions :
Step 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.
Step 2. Loosen the small lockring nut on the valve core
- Make sure to unscrew it completely.
- Skip this step if you’re using a Schrader valve.
Step 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 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.
Step 4. Once done, tighten the locking nut
- Make sure 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.
Step 5. Insert the valve cap
- Make sure it’s finger-tight so it doesn’t rattle and drop off unknowingly.
