Tire pressure on 150 20's
I've got a new 2008 King Ranch with the optional 20's. The door jamb says 35 lbs of pressure. I'm wondering if that was meant for the 17's that originally came on the vehicle. does anyone know the correct pressure for the 20's ?

The pressure on the door jamb is for your particular set up. The Pirellis are P-series tires, with I believe a max of 44 (Considered a extra load P-series).
Go with the 35.
Down the road, if you swap to tires with a different load range, then you will have to figure out what pressure to use for them.
