It is nitrogen.

The track and tires are both sprayed with a special solvent compound.
Mechanics change tires during a race to ensure optimal performance. Tires wear out due to high speeds and friction, decreasing traction and handling. By changing tires, teams can maintain grip levels, enabling drivers to drive faster and safer.
slick tyres are used.
