Let me correct that: all 395/85R20s used by the military are regular, non-MPT tires. Same goes for 365/85R20s. Putting them on stock Deuce wheels is not a problem, even if the manufacturers recommend a 10-inch wide wheel.
But 365/80R20s (former designation 14.5R20s) are MPT, also the 12.5R20s...
I've been through that phase and can assure that all three things will improve drastically once you stepped up to super-single radials.
I know it's a relatively big investment, but worth it every Dollar, IMHO.
