Hoosier recommends 30 psi cold and 38-40 psi hot for a 3800 lb car with driver.
Personally, no higher than 36 psi hot, and possibly lower. Cold starting point depends on ambient air temperature. Start at 30 psi cold if you are a novice, you won’t build as much heat in the tire as an advanced driver. If advanced, I personally have started the continentals GT-Is around 28 psi. Do a session, come in, and quickly get your pressures and bleed off as needed.
