The U.S. style NDT tire was very close to the German "M" tread. I'm not saying we copied it, but they do look a lot alike and the Huns had them first. In regards to another reply, They needed a tread design that would appear the same forward or reverse as not to give away the direction of travel. When I joined the Army in 89 we still had M151a2 Jeeps and M35's with the NDT's. They weren't worth a crap in bad weather like snow or ice. The post war tires had a round shoulder and the war time tire were square shoulders. The round tires would "float" really bad at high speeds. I'm surprised we used them as long as we did. The humvees use Goodyear wranglers 16.5 inch with combat wheels.
