Additional air can be pump into the tire filled with air because?

The original air in the tire is old and weak so new air pumped in is stronger because it's newer and faster ;) Just kidding, really though the pressure of the air in the tire compared to the pressure of the air applied to the valve stem is the determining factor to whether or not you will be pumping air in the tire or letting it out of the tire. 10psi in the tire and 20psi at the air chuck equals a 10psi difference, and if the air chuck is applied to the valve stem the tire will fill with 10psi more of air and will then equal 20psi in the tire if the 20psi air pressure can be maintained at the fill chuck by an air compressor. Why, because different pressures will want to equal themselves to each other if they are aloud to occupy the same area with the higher pressure always wanting to expand into the lower pressure area, like inside a tire.


What is the optimal air pressure for a bike tire and how much air pressure should be maintained to ensure proper performance and safety?

The optimal air pressure for a bike tire is typically between 80-100 psi (pounds per square inch). To ensure proper performance and safety, it is important to regularly check and maintain the tire pressure within this range. Insufficient air pressure can lead to poor handling and increased risk of flats, while excessive pressure can cause the tire to be more prone to punctures and reduce traction.


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 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.


Suppose you deflate a bicycle tire by depressing the air valve Why does air rush out of the tire and After the air stops rushing out of the tire is the tire empty?

Air rushes out because it is under pressure. Once there is no longer any pressure in the tire the air will stop flowing out. However there is still air in the tire it is just equal to the pressure outside.


How can you determine if your bike tire has enough air?

To determine if your bike tire has enough air, you can use a tire pressure gauge to measure the air pressure in the tire. Refer to the recommended pressure range indicated on the tire sidewall or in the bike's manual. If the pressure falls within this range, your tire has enough air. If it is below the recommended range, you need to add more air.


Where is the pressure greatest on a tire when its on the car?

Air pressure is the same throughout the tire.


What is the correct air pressure for a 2003 Road king?

The correct air pressure for your 2003 Road King standard tire is 18 pounds. The tire air pressure is dependent upon the type of tire.


What is best tire pressure for a 4 door 1999 Toyota RAV4?

The best air pressure, for your 1999 Toyota, is dependent upon the type and manufacturer of the tire. The best air pressure will be the recommended air pressure by the tire manufacturer.


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.


How does a tire gauge work to measure air pressure in a tire?

A tire gauge works by using a pressure sensor to measure the air pressure inside a tire. When the gauge is pressed onto the tire valve, it detects the pressure and displays the reading on a dial or digital screen. This allows the user to know if the tire has the correct amount of air pressure for safe driving.


Why does the pressure of an tire increase if the automobile is driven for a while?

The air in the tire is becoming heated due to the tires friction on the road surface. Heated air increases the pressure in the tire
