Correct tire pressure PSI for 255/40 R19 and 275/40 R19 tires?

[JRONET]

Hello,
I am waiting for my GT with performance pkg. to ship. Can someone please give the correct tire pressures for the 255/40 R19 and 275/40 R19 tires? I believe the pressures are different.
thanks for any help

It's a good thing to check, especially when taking receipt. The car will ship with the tires at 40 psi / 2.75 bar. The pressures should be lowered to the expected as part of the dealer's inspection process. But they don't always do everything they're supposed to.

I checked the Owners Manual and did not see a specific reference for those sizes. But when you sign for the car, check the placard in the Driver's door; it should list the tire size/s and recommended pressures for your car.

My door card says 32 psi front and back on my performance pack car with the same tire set up.

Yes take the time to check everything over yourself. The techs at my dealer did nothing except remove the plastic and clean out the car.
My tires were all different pressures. 28 to 36 lbs
Antifreeze low, just enough to cover the bottom of the reservoir.
Tranny and rear end were ok, but engine oil was below add.
Go over everything unless you really trust your dealer.
