moving from 225R75/16 to 235R85/16 PROBLEMS
Hi, More problems have reared their heads. The E-450 has a different rear axle, than the F-450. The F-450 will allow up to a 245 width with no change of rim size for the rear duals. The E-450...

Interesting idea. IMO Michelins are also more likely to have the highest safety margin built in above and beyond the ratings in their inflation tables. There was a reason they would allow you to run 7 years instead of 5 (I wonder if that is still true).
Blow outs and delaminations on properly cared for C tires for vehicles near their weight limits always used to be heavily biased toward the inner tires of the pair, probably because of reduced cooling. The most margin in the tire (by carefully selecting brand and model - was once XPS as the very best) along with extra dually spacing could be a good answer.
But it does take 4 or 6 wheels which gets expensive. Simply upgrading the tires to the best available can also go a long way toward increasing margin on weight and ride quality.
