How can I use a presta pump adapter to inflate my bike tires with a Schrader valve?

To use a presta pump adapter to inflate your bike tires with a Schrader valve, you need to screw the presta pump adapter onto the Schrader valve. This adapter allows you to use a pump designed for presta valves to inflate your tires with a Schrader valve. Pump air into the tire as you normally would with a presta valve.
