because they would be flat and you would be screwed
F1 teams use Nitrogen to fill the tires because of its low dilatation compared to air, a small dilatation in a F1 tire will result in unbalancing the car.
It is good to fill the tires of your car.
The best tires for a small car would be the ones that the car manufacturer recommends you use on the car. If you keep good tires on your car and check them every now and then you will get better gas mileage.
No
There's moisture in air. When you fill your tires with compressed air, the moisture goes in the tire too. Moisture then has potential to rust out the rim from the inside. They use other gas (nitrogen?) that doesn't have moisture. Usually garages will put green air valve caps on tires filled with gas.
well there really is no other way to inflate an inflatable object
they are filled up with regular air that our tires use but some cheaters in monster truck racing fill their tires up with water to make sure they land on all fours.
You fill the car with gas, you use up all the gas, then you fill it up again!
there is considerable debate about this, it is used in race car tires because the pressure is more constant from cold to hot. In theory you get better gas mileage because of this. I use it in my drag car and after a burnout the pressure doesn't rise like air when hot. The reason for this is that nitrogen has no moisture in it, the moisture content in compressed air expands and contracts at a big rate in relation to heat or the lack of.
Street cars air (which is manily Oxygen, nitrogen), race cars nitrogen.
You can fill a cylinder with gas.
that depends how you drive the miles on the car how the car has been maitained how the car runs the tires and the gas you use
