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.

Is inflated tire lighter?
No, heavier by the weight of the extra air put inside it. Even if you filled the tire with helium it is still heavier, although the additional weight would be less than the additional weight of air.
Why does a tire expand as you pump air into it?
because you're putting pressure inside the tire of the required psi recommended
What gas is in a tire pump?
There is no gas in a tire pump, only air.
Why does a tire get bigger as you pump it up?
Because, the air pressure hitting the tire, and as it hitting we put some air pressure into it so the tire is fully pumped up.
What is filled in the tire of aeroplane?
air
When you pump air into the tire of a bicycle what is the state of air in the tire?
Because I don't know what your teacher is looking for:At a pressure above atmosphericCompressedConfined
Why does the bottom of a tire pump feel hot when you pump air in the tire but when air is released the valve stem feels cool?
Because when you compress a gas like airit gets warm - which is what happens to the pump. And when a gas like air is allowed to expand, which is what happens when you let it out of the tire, it cools off - which is what happens to the valve.
What should you do if your motorcycle front tire goes flat?
WEll if you don't already have a pump get in the car and buy a pump and pump the tire already!
What is the name of the air filled tire?
pneumatic
Does a CO2 bike pump inflate the tire with CO2 or does it only use the CO2 as a driver for pumping oxygen from an intake on the pump into the tire?
The CO2 goes into the tire.
What amount of air is to be filled in tire?
Refer to the tire pressure chart on the drivers door.
Why tire pump gets hot when it is used to inflate an object?
Because of the friction created by the compressor piston
