nearly all Formula 1 teams uses NITROGEN for filling tyre. .The tyres are filled with a special nitrogen rich, moisture free gas to make sure the pressure will not alter depending on where it was inflated (this gas does not expand when hot) and NITROGEN holds tyre pressure for longer than air.A 20% Tyre pressure drop reduces tyre life by 15%.
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.
F1 tyres are filled with Nitrogen since it is a more stable gas than air
The F1 tires used in Formula 1 racing are approximately 305mm wide.
nitrogen
suspension.
They used to be used for when the weather was too bad for the 'full wet' tyre. Pirelli haven't made them for the current season.
Some are directional like the eagle F1, however most are not directional.
Soft tires are better because they are smooth on the track which gives them more speed.
most used is nitrogen..

Nitrogen is used in many aircraft tires.
only other gas i've ever heard of being used is nitrogen.
