    Yes I searched high and low for an answer before posting and came up short.

    Do I maintain the same pressures when switching to the same size tires in XL load rating?

    Staying with 255/70r18 size on my 2014 but going to XL rated. Can I still run 30/33 or do I need to change it since they’re now XL? Run the bed empty almost all the time if that helps.

    No, if you change tire size or tire load rating the pressures listed on the door sill are no longer valid.

    Use this to get you in the ballpark, and then you can adjust up or down depending on your truck and load.
