I can also confirm, as an owner/operator of both an M-37 and an M-817, that the Military spec NDT tires are NOT meant for sustained highway use. Let me foot stomp that .... NOT!!! If you plan on driving much on improved roads, you can either replace them now or replace them soon. The NDTs are soft rubber and were spec'd for off-road conditions in the Fulda Gap. Nothing else.
Okay, other than that, let me say what an absolutely COOL TRUCK that is!!! Welcome to Stovebolt.com!!
