Default Recommended tire pressure?

Hi Everyone, I'm getting ready for my first DE tomorrow. My '95 has 18 inch turbo look wheels and Bridgestone Potenza RE750's, 265/35 R18 93W in the rear and 225/55 88W in the front .

What is the recommended pressure for these tires for a car control clinic and autocross event? The door sticker lists 36 psi but that is for 17 inch wheels.

Outside temperature should be in the high 40's in the morning, warming up to 65 mid day.

Thanks for your help!

short low speed cone dodging? probably 32-34 all the way around. Highspeed track time? 28-30 all the way around tops.

Since this is your first DE and with these cold temps, I dont think you are going to generate too much heat on them. I would advise to start 32 front and 34 rear and take it from there. After your first session drop off your instructor quickly and then get out of the car and check the pressures. For sure you want to be below 40psi HOT. I would blead to be around 34-36 HOT after the sessions that will follow. Its all going to be relevant to the heat you are going to generate on them with these cold temps.
Have fun! I'm envious!

Danny's advice is right on - as usual.
I'd add that you should defer to your instructor. DO NOT make any pressure changes without informing & getting the approval of your instructor. For your 1st DE, don't obsess about tire pressures.

For autocross and the track, I love 35 in the front and 37 in the rear. I've tried a bunch of different combos and this one works best for me.
