Mismatched tires on a 5 Ton

[CES 3245th]

I realize this is not the norm, but I bought the truck this way, So go easy. I have three Michelin 14x20 and three Goodyear 14x20 I'm definitely going to change over to the Michelin. But my question is what is the ramifications of running two different type tires with two different weights and different heights in size . Is there a TM out there somewhere stating anything about mismatched tires?

The military runs them with mismatched brands evidently as that is the way a lot of the trucks hit the drmo lots. Since they are all 14.00x20 I don't see a problem running this way until you find the matching ones.that is how my first m931a2 was when I bought it.

Different heights? Huh? 14.00x20 should all be the same height. (Well, wear differences and all...)

That isn't enough to worry about. 3" yes, .3" is negligible.
