Best tire pressure for 275/35 R18 RT615

I tried the search, but no real luck. Does anyone have an opinion of tire pressure for this setup 275/35 R18 on 9.5" wide wheels. I started at 40 PSI but I am thinking this may be two high. Any thoughts?

I think I've heard from Brian Goodwin that 29 psi works pretty well.

i have that size in 19's and ive played with multiple setting, and i actually am very comfortable at 27psi..i have great rear grip and i eliminated all of that "bouncy" skidding feeling when htting a high speed turn. Not sure how this will work on tire wear and such but it feels comfortable for everyday and feels great when having a lil fun. My front tires 27 psi on 235/35/19

your pressure is on the sticker inside the door jamb. lower it to get a little more grip.

I run 28 psi cold pressure at all four corners for autocross, but I would probably suggest a couple more lbs for street.

I lowered my air pressure to 34 front and 32 rear. It does corner better and has less understeer. I may try a lower number but I need to drive it for a couple of days first.

Thanks Guys.
