Inside the tire there is a tube, which is basically an air bladder - like a balloon with a strange shape and a valve attached. If it's intact and made out of an air-tight material it can be inflated.

When would the air pressure inside a bicycle tire be lowest?
When you are not sitting on it.
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.
Which have more pressure inside bicycle tire or tractor tire tube?
Depends on the type of bike. A skinny tire road bicycle will have several times higher pressure than a tractor tire, while a wide tire Mountainbike can have anything between the double to 1/3 of the pressure of a tra tire.
Is Pressure inside a bicycle tire higher than the pressure outside?
If the tyre is inflated, yes. If it has been completely deflated, no.
What does tire pressure mean in a bicycle?
how much air is in the tire
What does a bicycle tire gauge measure?
ANY tire gauge measures air pressure in PSI.
How many PSI of air is in a 29-inch bicycle tire?
The inflation pressure is on the sidewall of the tire.
A bicycle tire at rest has 85 psi pressure and occupies 4.0 L at 33 °C.What will be the resulting volume inside the tire if the temperature increased to 45 °C and thepressure increased to 90.0 psi The amount of gas inside the tire remains constant?
ok
What creates pressure in a bicycle tire?
The pressure increases, and the molecules collide with the tire's inner surface.
What is a bicycle tire?
A bicycle tire is a tire which fits on the wheel of a bicycle or similar vehicle.
Is there a limit to the amount of air that can be pumped into a bicycle tire?
Yes there most certainty is a limit to the amount of air that can be pumped into a bicycle tire. Put too much air in the tire and it will explode. The maximum air pressure for the tire is listed on the sidewall of the tire.
Why the pressure of the air inside a car tire increases when the car is driven at high speed?
When you drive the the tires create friction with the road when they rotate. Friction creates heat. The air molecules in the tire heat up and expand. Since the tire is rubber and sealed the tire expands with the pressure of the hot air.
