Good to see that these tires are still being made and sold (if not in the USA...). They have been in use for years by the folks in Norway, Denmark, and Israel (and others).
I have had them on my tire page for some time, mainly due to folks acquiring them on trucks returned to the USA from overseas...
http://www.garbee.net/~cabell/photos5.htm Has some old, tired, photos of these on civilian Dodge Power Wagons (same rim as the M37...).
Could you post the sidewall info from the tires that you just mounted MM? It would be nice to update my files.
Thanks,
PS: I can hear the tires on my Cummins powered M37... The truck makes different sounds depending on driving surface, air pressure, and tread wear... You can pick up on what is tire, transmission, engine, body...it's like hearing a guitar even though it is playing in a band...
