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.
The pressure increases, and the molecules collide with the tire's inner surface.
Deepika sharma - more the area less is the pressure exerted by it
Air goes in it the pressure increases and the tire becomes harder. If you keep pumping it'll eventually blow up.
Pressure inside of a balloon is created by the movement of the air molecules against the inner surface of the balloon. The more air inside the balloon, the more molecules that are hitting the same surface are, so there is more pressure.
The obvious answer is that the more there is the more there is. More molecules more density, more pressure inside the vessel.
Because - the skin of the Basketball 'locks' the air inside so it can't dissipate. The more air you pump into it - the higher the pressure gets.... until it bursts.
because of the pressure. when you add more air to the tyre, or inner tube, the air inside squashes together, which makes the tyre hard. the pressure is measured is PSI, or pounds per square inch. a fully inflated mountain bike tyre should be around 40 psi. hope this helps
Flabby tyres produce more friction with the road.Less air pressure creates more surface friction, the less surface friction there is the better. (Example look at the very skinny narrow tyres on road racers as they don't need a lot of surface friction while mountain bikes have thick tyres as they need more friction)
You are forcing more air into the same size space. The oxygen molecules get closer and closer as you continue to push air in. Eventually the tire will give way and release the pressure.

Bicycle Victoria's motto is 'More People Cycling More Often'.
Pumping pushes more air molecules into the ball. That makes more molecules moving around inside of the ball and more molecules colliding with the inside of the ball. All of those collisions (trillions and trillions) push the inside of the ball out. When the temperature is increased, the molecules move faster. Faster molecules collide with the inside walls more frequently, which also increases the pressure. You can test this by pumping up a ball then putting it into the freezer and see what happens to the pressure.
