I did read that many people here prefer to run them at 40 PSI.
Curiosity question. If you run LT tires at 32 PSI listed on the door, can that cause any safety issues or does it just only means you will have less fuel efficiency and uneven wear?
Thanks again.

Yes to all of your questions for normal driving. Airing down off road at slower speeds is of course an exception. I ran my KO2's at 32 for a while and they began to cup, that is when I looked into it and discovered I needed to adjust for the LT tire. After that, they went 90k no kidding. Now on my second set on the runner and may put some on my Land Cruiser unless I decide to go with Defenders.
Additionally, if you have heavy accessories like bumpers, skids, RTT, etc. then you may want to research and recalculate your weight and re-run the math on the inflation tables listed above for maximum performance. Hope this helps.
