First...WONDERFUL to find you, Peter, and your thoughts on tires !!!!
Add that there is more to it than just PSI vs tire size/type/etc...the rim width also matters... a lot
Dependent or factored by the OEMs min/max rim recommendations (on that, not many understand the ramifications of NOT following an OEMs recommendations), which is a bell curve they establish for the performance/specification they designed & certified to
That the narrow end of of their recommendation will have more sidewall bend-back...that creates more flexing, which reduces the sidewall's efficiency (more heat and higher rolling resistance), increasing the slip angle and a reduction on other attributes of 'that' tire...my kind of desired/demanded tire performance suffers with a narrow rime width
Wider with the exact same tire will have less sidewall bend-back. Less flexing (less heat, higher rolling resistance), less slip angle, etc...my kind of desired/demanded tire performance is up there and now have a rim width 2 inch wider than the OEM recommended 8". Perfect for my driving style
Another attribute to your comment of AF/Mudder/Off-Road/etc vs Highway tread pattern into the sidewall is that the OEMs design the tread to sidewall area differently...generally speaking. There are some whose designs are exactly the same between them.
A true off road designed tire will have the tread area invert to form a cup when aired down to, say 15 PSI. Also, the apparent tire dia changes to something in the neighborhood of 8-10 feet or more (+ 3 meters) with the sidewall bulge to increase the contact width
Why running aired down tires off road above 15 MPH is deadly to the tires longevity
Again, much appreciate your comments !!!!
Currently running Bridgeston Duel Revo LT265/75R16E's on alloy 16x10 wheels and love them after having several sets of Michelin LTX-AT and LTX-MS's

I will show 2 pictures, that show the inpact of treathprofile on howmuch the tire can deflect without overheating the rubber .
Used it to prove that an ofroad( looking) tire must have lesser deflection for savety then a road tire.
snip...
So , besides using experiënce of others here, you can also yudge a new tire yourselfes by the profile.
If you only do on road driving , you better take a normal tire, and no offroad type.
And if do want an offroad type , dont take the agrasiv looking types as the last picture, but the middle type left on the first picture, and use an higher tirepressure for it .
I can help you with calculating a needed pressure for it , once you have one.
