Michelin Military Tires available in Canada
 

Found on the European Michelin web site:
http://www.michelintransport.com/ple...que=51&lang=EN
Their catalogue includes the military treads and lists permissible speeds, weight capacities, dimensions etc.
It also makes reference to "flat ledge rim" and "dropped centre rim" fitting, which sounds to my untutored mind like our never ending debate about fitting "British" or "American" rims.

Michel from Militarytires.com 450-424-2399 was up from Hudson, QC at Gracie's last night and mentioned that he had fairly good availability of some sizes of these tires.

That's where I got mine from. He does indeed have a good selection. I would recommend his tires.
