"LT" tire pressures on Expedition
I moved up from "Heavy Load" tires on my Expedition to real "LT" tires. Max air pressure on the new tires is 80#, max pressure on the heavy load tires was 50#. I always ran my other tires at max press...

What is the pressure rating for your wheels?
Thats a good question , I dont know. I have the stock 20" wheels on my truck. I used a air pressure guide for a tire installer and it looks like if I use 50 - 55# of pressure I should get all the capacity I need. (in the neighborhood of 2,335-2,360# per tire).
I also read that if I go above 60# I may blow out my valve stems. I think I will run at 50, maybe 55#. The stiffer sidewalls should make a nice difference.
Be careful what you read on forums, especially RV ones. You're not going to blow out a valve stem by airing up to 60 lbs, or even 120 lbs, nor will your factory OEM wheel grenade. The pressure rating of your OEM wheel, if it even has one, will be more than the pressure any tire requires that will physically fit on it along with a substantial margin for safety/ error. Don't inflict yourself with a case of Rv board OCD.
I usually ignore idiots of this sort, but the OP and anyone else interested in uprating tires would do well to educate themselves as to the facts about wheel pressure and load ratings.
I'll have no further comment, life's too short to debate with people who are willfully ignorant and choose to provide dangerous advice.
