Starting Cold Tire Pressure?

[Tims65]

I'm finally headed back out to the track tomorrow morning and I can't find my notes on my tire pressure.

What should my starting tire pressure be for:
225/45/17 front
245/45/17 rear
Falken Azenis street tires

I was thinking I should start around 32 psi cold. I have a pyrometer, but I want to minimize the tuning, as I only get 3 sessions.

Thanks,
Tim

I start my slicks off with 35 front, 30 rear. This works well with my camber setting at my local road course. I get pretty even temps across the tire with about a 10 degree jump from inside to middle and 10 more from middle to outside.

The only way to know for sure if you have the right camber setting/tire pressure is have a buddy take pressures and temps after a few hot laps. I usually line up someone in the hot pit lane, get 2-3 flying laps in, come into the hot pits (no cool down lap), have them take readings and carry on for the session. You can then look over the data between sessions and make changes if need be.

Is it a probe pyrometer? The infared ones are not going to give you a real tire core temp reading (which is what you want).

Thanks Shaun, I've got a pyrometer probe, just want to be close, because I won't have much tuning time.

Thanks,
