I am sure you have seen car tires that had the edges wore away and still like new tread in the middle. That is a perfect example of what I am saying. That comes from running the pressure at car makers recemonded 30psi instead of tire makers recemonded 35psi. Now the tractor tire makers recomend pressure equalling the 30 car pressure so you have the same thing, then you add the cast weight and how many increase the pressure to carry the aditional weight. That answer would be very few. Now add weight like a big bale on the back and that tire is way under pressure and the tread is bending in like that car tire with no tread at the sidewall and full tread in the middle. That tells me that the pressure is higher at the sidewall than the center of the tire. Now if you up the pressure enough it equals out but how many do that? Very few. Fluid will keep the same pressure on each sq in of tire on pavement if in center of tire or edge no mater what the load unless it is so suverily overloaded the sidewalls cannot handle the load at that pressure. I know that I am not a good speller.
