18 months ago I did the same. 2013 F150 , going from P to Michelin E rated. TT is about 6200 +/- loaded.

I contacted Michelin either by phone or chart, can't remember which, and they told me the E tires @ 55psi would equal the max load rating that the P tires had. Of course with stiffer sidewalls. No need to go to 80psi.

This. I did the same thing.
Michelin wanted info on the type and pressure of OEM tires, and then came back with the proper/equivalent psi for LT-Es.
Didn't get a new sticker though. Would have been nice.
