Car tires are typically filled with air, which is a mixture of gases, primarily nitrogen (about 78%) and oxygen (about 21%). Some drivers opt to use pure nitrogen instead of regular air, as it can help maintain tire pressure more consistently and reduce the rate of oxidation in the tire. Regardless of the choice, maintaining proper tire pressure is crucial for safety and fuel efficiency.
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.
because they would be flat and you would be screwed
well there really is no other way to inflate an inflatable object
Nitrogen
Nitrogen.
It is nitrogen.
Street cars air (which is manily Oxygen, nitrogen), race cars nitrogen.
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.
Nitrogen, because it is an inert 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
most used is nitrogen..
It's just regular air.
