Be sure the pump you are using has a Presta head on it. If your pump doesn't have both, an adapter is available at bike shops for around a dollar.
The Presta valve must be manually unscrewed before attempting to inflate, to permit airflow in either direction. The screw, located at the tip of the valve, remains within the valve housing even after it is unscrewed; unscrewing the valve permits the plug to move up and down within the housing. It must be unscrewed before attaching a tire pump.
Once unscrewed, tap the tip of the valve to allow a small bit of air to escape to release the air seal in the valve.
With the pump in place, lock the pump head on with the lever on the pump. Most pumps will be locked with the lever in the up position.
As an added measure, before pumping, you might brace the valve by hooking one finger around the valve to reduce the chance of damaging it during inflation.
Pump with a slow, strong and steady motion to reduce fatigue (yours) until the desired tire pressure is reached. Change the lever to the unlock position to remove it.
Once the tire pump is removed, the valve should be screwed down to prevent accidental air leakage. A screw cap provides protection to the valve top, although the cap is not necessary to keep air from leaking.
it helps with keeping the tyres inflated.
Air is used to inflate tyres , power air-tools , sustain life,
Air is normally used to inflate car tyres, sometimes just nitrogen is used.
nitrogeon is used to inflate race car tyres due to the consistent tyre pressure throughout different tempertures.
i need to inflate the rear tyres of my tractor using the engine. i have tried using a car pump but this doesnt work. im sure its to do with the pressure, i dont know how this could be done. Thanks
Mostly 'air' is used to pumb up tyres however sometimes nitrogen gas is used as it is deemed safer because it excludes the oxygen.
the prefix is in-
If the tyres would not be round they will not move.

how does friction help car tyres?
Assuming you're talking about the tyres... The tread on the tyres channels water away from the wheels - allowing the tyres to grip the road better than if the tyres were completely smooth.
Inflate is a verb.
