Tire Pressure for Michelin LTX A/T 2

[FLWanderer]

Anyone have info on correct tire pressure for Michelin LTX A/T 2 Load E. The original
BF Goodrich 275/65R18 as per vehicle sticker...30 frt and 33 rear. The normal max load pressure for those was 44 lbs. The 275/65R18 Michelin LTX A/T 2 Load E max load pressure is 80 lbs, and I am running them at 55 lbs right now. I upgraded to Michelin LTX A/T 2 Load E because of the 5th wheel I tow. Want to be safe. This thread is referring to air pressure in normal driving conditions. No rv towing implied....

Thanks
