How do I properly fill a bike tire with a Presta valve?

To properly fill a bike 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 inside.
2. Attach the pump nozzle securely to the valve by unscrewing the tip of the nozzle and pressing it onto the valve.
3. Pump air into the tire until it reaches the desired pressure, which is usually indicated on the tire sidewall.
4. Remove the pump nozzle carefully and screw the top cap back onto the Presta valve to secure it.
