Yes if the valve is leaking. But in general the answer is no.
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.
Sounds like someone let the air out. Another possibility is that it is leaking at the valve stem. It may only leak when you are moving. The centrifugal force causes the valve stem to bend sideways and leak. It could also be you parked it with the leak on the bottom and the weight of the car sealed it. I would remove the tire and check it throughly with soapy water for a leak.
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
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.
It is the air valve on the tire, where you put air into the tire.
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.
A tubeless tire can get punctured but air will leak slowly.
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
A slow air leak can be caused by a puncture in the tire itself, a leaking valve stem, or improper sealing between the tire and rim. Bring the vehicle back to the garage you bough the tires from and have them inspect it for leaks. When they remove the tire to inspect it, they will clean the outer edge of the rim (to make it seal better) and replace the valve stem, even if there is no hole in the tire.
One way valves are used on any tires. It lets you air up the tire and the valve keeps it from leaking air back out. If you want to check if your vale is leaking, just pour a little water on to the valve. You will see bubbles comming form the valve if it is leaking. If no bubbles, there is no leak.
Press the pin in the centre of valve.
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.
