Description
Check tire pressures or quickly adjust pressure when you're "airing down" for some wheeling. To deflate your tires, simply screw the EZ-Tire Deflator onto the valve stem cap threads. Turn the Deflator knob to unscrew the valve stem core. Slide the collar up to quickly release the air and then back down to stop at your desired setting. Screw the valve core back into the valve stem and remove the EZ-Tire Deflator. Saves time and provides safe & accurate tire pressure readings.
