Sim Racing Tire Pressure Calculator

Calculate the correct cold (setup screen) tire pressure based on your desired operating pressure and track conditions.

Cold Pressure

-- PSI

Typical GT3 range: 26.5 – 28.5 PSI

Desired Hot Pressure (during race stint)

PSI

The pressure you want to see in telemetry during your stint.

Expected Tire Operating Temp (°C)

°C

Tire surface temp during your stint. GT3 tyres typically reach 80–100°C.

Ambient / Pit Lane Temp (°C)

°C

Current air temperature in the pits where you set the pressure.

Setup Screen Cold Pressure

-- PSI

✓ Optimal Range

Target Operating Pressure 27.5 PSI @ 80°C

Typical Range 26.5 – 28.5 PSI
