What kind of tread is used to avoid tearing up the road?
I know this article is satire, but to answer your question: The standard tread on the M1 has rubber track pads.
Fun fact: The exhaust from the Abrams blows away from the rear of the vehicle and is very hot, as more than one tailgating driver on the autobahn would discover. We used that same exhaust to boil water for coffee and shaving.
Cheers!
