Because, by pressure differential, there is a gas flow from the high pressure tire to the lower pressure environment.

What does air leave a tire when the tire valve is opened?
Air leaves a tire when the valve is opened due to the pressure difference. Since the tire has more pressure than the air outside, the tire air will escape until the pressure equalizes.
Why does air leave the tire when the tire valve is opened?
Air leaves a tire when the tire valve is open due to the pressure. The pressure outside of the tire is lower than the pressure inside the tire.
What is the type of air valve?
if you are asking about the air valve on the tire to add/let out air then it is a schrader valve or an American valve
Where is ths schrader valve on 2005 ford f 150 4x4?
It is the air valve on the tire, where you put air into the tire.
what is the basic function of an air valve?
The basic function of an air valve is to control the release of air that is under pressure. Common places where an air valve would be used is on an inflatable tire. It is used to add more tire pressure to the tire.
Why won't your bicycle pump will not pump air out?
It's likely there's a rupture in the diaphragm that pulls the air into the chamber and then pushes it out to the valve. There are two "reed" valves in the pump that only allows the air to go in one direction with each valve. So when you pull up on the handle to fil the pump, one valve allows air in, but not out when you push down on the handle. Another valve at the bottom of the pump allows the air out when the handle is pushed down, going to the tire. There is another vavle on the tire that is opened only with the pumps adaptor, to allow air into the tire.
Where is the shradder valve on a 1995 Dodge Caravan?
I have heard the shradder valve is the tire valve stem ( internal valve ) that keeps air in the tire or else you will have a flat.This valve has many applications including air tanks
How do get the air out of the tire?
Press the pin in the centre of valve.
Air shocks has to mouch air how do you remove?
The shocks have a air valve just like a tire valve, just take the cap off the valve and depress the insert in the valve to let air out.
When you inflate a tire where does the air come from?
The air comes from the atmosphere. It is compressed by the pump and forced, through a valve into the tire.
Will your tire leak air if your valve covers are off?
Yes if the valve is leaking. But in general the answer is no.
Why does air come out of a bicycle tire when you open the valve even if the valve is pointing up?
Because the air inside the tire is under pressure. Gas always flows from a region of higher pressure to a region of lower pressure. As the pressure inside the tire is greater than the pressure outside, the air always comes out of the bicycle tyre.
