I am running the Ventus V12 M tire size of my 3.0si coupe. I talked to Hankook and they said 40 psi front and back is fine. I did the LVPCA track event at Las Vegas Speedway with the tires at this pressure and they performed very well. The pressure also is fine for Normal driving and doesn't give too harsh a ride. I am very pleased with the tires.
