Air is used to inflated car tyres but cars can be equipped with nitrogeon inflated tyres but this is usually only beneficial to race cars
Nitrogen.

Nitrogen
You can get your bike tires pumped at a bike shop, a gas station with an air pump, or by using a portable bike pump at home.
Nitrogen and oxygen = Air
It's nitrogen.
Usually it's just ordinary air that gets pumped in there. Some use Nitrogen, but the benefits are marginal.
Helium is typically pumped into balloons because it is lighter than air and gives the balloon its ability to float.
I think it is Nitrogen. The normal air mixture pumped into regular road cars is not efficient at high speeds and will lose pressure easily. If that happens there could be catastrophic consequence at high speed. That is why they use nitrogen If you pump nitrogen into the tires of your regular road car, you need not check tire pressure for 3 months.
Airless tires are tires which are not pumped up with air in the traditional way. Vehicles such as ride-on lawnmowers and golf buggies use airless tires.
I assume you mean tires - not tyers... So some race cars use Nitrogen for the properties that it has. It is noncombustible, has larger molecules and is absolutely dry.
