My new to me '06 CC KR 4x4 has the 20" optional wheels. The sticker in the door has specs for the 18" tire size. Running 275/65 Nitto Terra Grappler. Checked the Nitto site and tried a search to no avail.

What pressure should I be running?

you are either drunk, or terrible at searching the interwebs. Nitto clearly states here Nitto Tire - Fueled by Enthusiasts the max tire pressure is 80 psi. So 60 psi empty would be great and air up the rears to 80 if you are towing heavy.

The Nitto website says to check with your tire dealer for pressures for tires other than the original on the truck. Since it was late Saturday and no shops were open I thought I'd ask here since this is site is for information on these kinds of trucks.
