LT265 x 75 R16 tires recommendation.
I have a 2000 F250 that currently has BFG Rugged Terrain tires on it. They probably have less than 8,000 miles on them but seem to have excessive cracking on the sidewalls where the tread cap attaches...

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.
This picture shows that if the profile blocks cover a part of sidewall it leaves lesser sidewall to flex, or with same deflection more bending of the remaining sidewall so produces more heat at the overgoing of sidewall to treath.
If temperature of rubber goes above a sertain temp, the rubber hardens by producing to much sulfur bridges , and so the rubber structure damages, and every next bending of it tears it a bit furter loose and in the end a blowing tire. once the damage is done to the structure of rubber its ireversible.
What you now see is the beginning damage with those crackes.
These kind of tires need higher pressure then a road tire , to give it lesser deflection so lesser heat at the critical places, wich gives lesser comfort and gripp.
If you have next kind of tire with even more agressive profileblocks that cover almost half of the sidewall, I have seen picture of tore sidewall directly at the edges of the profile blocks.
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.
