This is one of the first things you learn in Chemistry class. PV=nRT where n and R are constants and pressure is dependent on temperature and volume. The pressure on the walls of the tire is a reflection of how energetic the molecules of air are.

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.
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.
The air pressure inside a tire?
scalar
What causes pressure in a car tire?
The air molecules bouncing around off the inside of the tire. If you force something into a confined space that is usually allowed to be free it will exert pressure(Force) on th walls of it's container. An increase in tire temperature or friction will cause the air pressure to increase while colder temperatures will cause it to decrease.
How does air pressure act on car tier?
air pressure helps on the inside of a tire but on the outside it does not usually help. as an observation if you get a flat tire and put air inside the tire it gives pressure on the inside were the hole is but if it is on the outside and lets say a pipe rolls down the highway and it hits your tire air pressure helps it make a hole in it or make it flat.
Is air pressure inside a tire vector or scalar?
Scalar
When would the air pressure inside a bicycle tire be lowest?
When you are not sitting on it.
How do the particles inside a car tire cause pressure on the tire?
Tyre pressure is caused by the air particles inside the tyre
Why does your head not get crushed with atmospheric pressure?
Like the air inside a baloon, the fluids inside your body exert pressure. This pressure inside your body acts against atmospheric pressure. I was looking for the answer for a school assignment! Textbooks help!
Why does a tire feel harder on a hot day?
The air inside the tire heats up, building the pressure. The pressure is exerted on the walls of the tire, making it feel harder.
What happens to the air pressure inside a tire when it is warmed?
The warming air would expand and the tyre pressure would go up.
Why does a tire expand as you pump air into it?
because you're putting pressure inside the tire of the required psi recommended
