Would you run these tires?
I noticed this today as I was getting the TT ready for a run this week: Have a 4 hr trip planned for Wed into Easter weekend. Would you run these tires? Tires are BF Goodrich ...

My Travel trailer tirepressure calculator gives only 63 psi with all the reserves and then going from only 10% of totalweight on pin=850 lbs. Your given 1200 lbs is 14.1% and this then would only need 60 psi.
another spreadsheet filled in with that 1200 as pinload gives even lower pressure of between 56 to 62 psi needed for speed below 87m/h.
so my conclusion of using to low pressure must be wrong.
Other possible reason can be alignment like camber. probably the other sidewall does not have those crackes in the lower part of profile blocks.
Your picture shows most damage on left side of treath.
Camber can be roughly measured with a water level, yust to see if its extraordinary . then one sidewal deflects more and produces more heat. Hold the water level straigt up against the rimm, and make the airbubble between the lines, and see if there is large diffence in space at botom and top of rimm. Dont hold it against the tires because they have a bulbe in the sidewall at the bottom , wich would give valse negative camber angle. Seen from behind negative camber would give this seen from behind or front /-\.
Positive camber this \-/.
Damage by heat only happens when driving at speed, standing still the tire can stand much more bending of the sidewalls.
But when you are using a weight distribution hich, the load on tires is when connected to car shifted to trailer wheels and front wheels of towing car. Then it is possible that instead of 7300 lbs you even have 8000 lbs on trailer tires .
But then even filled in my pressure calculator gives 70 psi as highest pressure , so you would also be OK with your 70 psi filling.
