Default Proper tire pressure for 20" tires - Nito 555's ZR

Currently have a set of Nitto 555's ZR on my Work Rezax wheels. Here is my set up: 245/35/20 (20X9) Front & 265/35/20 (20X10)Rears. What is the proper tire pressure for all four corners. I would like to know what tire pressure other members are running on here. Your help is much appreciated.

I've always kept about 38 psi cold in mine. Most people seem to run between 35-40.

Thats actually the MAXIMUM ALLOWED PSI... recommended PSI should be on the drivers door jam.

If your tire's have XL on them which indicates extra load (which yours do) you should have them around 40. http://www.tirerack.com/tires/tiretech/tirespecskey.jsp

Well, I spoke to Brandon who is the sponsor here: "You should use the recommended inflation pressures on the inside of the door jam, you may want to bump them up from that 2-3 psi."

My problem is, my door jam sticker is completely faded so I have no way of knowing what the stock recommended psi. I'm at about 35 psi right now.

Higher psi will avoid dents and will give you more even wear if the car is dropped. I am ususlly at 42 psi. The shop that does my wheels prefers 45 psi. Seems a little crazy so I just leave it at 42
