Tire Pressure during Racing

[jackrush]

I will be going to Monza on the Formula 1 Track this Sunday. Does anybody know by how much the tire pressure should be reduced for racing?

What kind of tires?

One big factor is how hard you go.
I raced with Kuhmo's at the Autobahn - 3.5 miles , lots of turns. but it was my first time out. I started out at thirty and it was fine at first but as I started going faster, the pressure built up. It started to get really squirly so I checked the pressure, it was over 40#s. Next time I plan to start at 25#s and check them often.

I assume you are running PS tires. Assuming temp is about 75-80 deg and sunny, I suggest you try starting with 35, expecting to hit 45 when hot. check after the first stint before they cool off and adjust while hot to 45. if you don't like the handling, reduce it a few degrees. That is what I do neway.
