What is the pressure for gt4?
Pressure
For GT3, Cup and ST cars the tyre pressure between 27.0 and 28.0 PSI is optimal for dry tyres. For wet tyres, it is between 30 and 31 PSI. For GT4 cars, tyre pressures between 26.5 and 27.0 PSI are optimal while racing in dry conditions.

What should you think of:
Get tyre pressures in the range between 27 - 28 PSI resp. 26.5 - 27 PSI for GT4 cars.
Use IMO tyre temperatures for tweaking of camber and toe settings
If for whatever reason your tyre temperatures aren't in the operation window, use brake duct settings, since heat from the brakes also effects tyre temperatures

Tyre Pressures
All GT3 dry slicks: 27.4-28.0 psi
All GT3 wet tyres: 29.5-30.5 psi

All GT4 dry slicks: 26.5-27.5 psi
All GT4 wet tyres: 29.5-30.5 psi

From my own experience in our GT4 league last season i noted that GT4s require careful pre race work as the tire temps are affected by several things. If you test on qualifying fuel test also on race load, half load etc.
