I know PSI rates differ dramaticly. But saying your tires are rated at 50 psi is irrelivent to your Jeep. A one ton van with 1- 1 1/2 tons of extra stuff needs to be at the rated 50- 65 psi to allow the tires to ride correctly. But a tire rated for a 3/4-1 ton truck stuffed under your light weight Jeep isn't considered when figuring out the load rating. I ignore those ratings unless they are on the right rig. But checking for a pattern or imprint is the easiest ways to get a desent idea.
Just check the tread pattern after rolling through a parking lot someday. If the dust touches evenly from the edge to edge of the tread then you're probably OK. But if it isn't touching the outer edge they are way to high. You will get better mileage because you're running on 10.5 tires instead of the full 12.5. But you wearing the center of the tire out. Heck 35 inch tires might need that because of the tall side wall??
If you have one of those cool inferred thermometers you can messure the temp in three spots left edge, middle, right edge, and this will nail it down perfect. Good old racing tire test.
Obviously everyone does things differently. But I had to pass on the info. My BF AT's on my 79 CJ sit 28 psi as mentioned before. My savero MT's (??) sat at 24 psi on the street. Once you figure vehicle weight, rim width, tire size, side way thickness, etc etc each set up is going to be different
