How do you properly pump a bicycle tire with a presta valve?

To properly pump a bicycle tire with a presta valve, follow these steps:

1. Unscrew the top cap of the presta valve and press down on the valve to release any air trapped inside.
2. Attach the pump nozzle securely to the valve by unscrewing the small nut at the top of the valve.
3. Pump air into the tire until it reaches the recommended pressure level, which is usually indicated on the tire sidewall.
4. Remove the pump nozzle and screw the nut back onto the valve to secure it.
5. Finally, replace the top cap on the valve to prevent dust and debris from getting inside.
