Did find what I was looking for according to Michelin (at least for truck tires): Page 176 (182nd page, but numbered 176) in this Manual.

Find it interesting that Michelin standard is half of the Bridgestone standard. Bridgestone says .125 inch. Michelin says .062. I think .125 (that's a freakin 1/8 of an inch!!!) is ridiculous.
