🛞 Tyre Compounds

• Mandatory Race Tyres: C3, C4
• Q3 Tyre: C5

📊 Pressures & Camber Prescriptions

Cold Pressure Cooling Curve

• P_front = (T - 70) * 0.121 + P_startf
• P_rear = (T - 70) * 0.118 + P_startr

Where T = Tyre temperature (°C), P_startf = Minimum starting pressure on the front axle [psi], P_startr = Minimum starting pressure on the rear axle [psi].

⏱️ Maximum Heating Times and Temperatures

• Slicks: Max 2h (70°C)
• Intermediate: Max 2h (70°C)
• Wet: Max 2h (70°C) (Temperatures refer to tyre tread and sidewall temperatures, not blanket or controller set-point temperatures.)

📝 Tyre Notes & General Notes

Important Guidelines:

• Not permitted to switch tyres from their originally allocated position.
• Do not subject tyres to large deformation or heavy impact.
• Do not leave fitted tyres exposed at an air temperature lower than 10°C and/or any excessive UV emission.
• Cut-off time for fitting tyres on Sunday morning: 4 hours prior to the race start.
• Tyres may only be heated prior to the session in which they are intended to be used.

• FIA Checks during the event:
  • Starting pressures
  • Cold pressures (according to cold pressure cooling curves)
  • Re-heat pressures
  • EOS Camber
  • Maximum tyre temperatures and times in blankets
  • Tyre swapping
