First time Jeep owner here. I just took delivery of a Granite Crystal 2021 Sport Altitude and absolutely loving it. Been reading forum posts on ideal tire pressure and it seems most ride at 36 psi or lower. I was surprised to see the recommended cold temp psi listed on the door was 38 psi. Are others seeing the increased psi on newer JLs? I have no idea if a few psi makes a big difference but I'm considering running at 35-36.
