I ended up just going with MRAP wheels and 14.5 r 20 Michelin X tires....
Just be extremely careful while driving your "Beast" down the road: 1) Surplussed 14.5R20 XL's have earned a bad reputation, already... not because of being bad tires, but from where they came from- and
how they were used. (M35A3 with CTIS...)
2) That combination - MPT-type tires mounted on std, non-MPT wheels - sure is a bad choice... and an accident waiting to happen!
Explained,
here...
I see what MRAP wheel you have and I can confirm this: actually your tire's
sidewall - and
not, as should be, the tire
bead - is resting against (or worse, interfering with...) the rims bead section!
Running only at max. TP may help in this case. But lowering air pressure increases sidewall flex- and the risk for premature tire failure!
Sorry if this is not exactly what you wanted to hear, but someone needed to warn you...
