The door panel says 36 PSI, I took them down from 41 to 38 and I'll probably drop more to 35-36 as I'm reading that helps handling. Also note I said 1 month from built to delivered - it was actually 2 months for me as it got stuck waiting for a rail to California. (just edited original post)Congrats on the Jeep and thanks for all the info. Making mental notes of all these little tips and tricks. What's the recomended PSI for the 20 inch wheels/tires?
