I got a follow up question to my sidewall post a while back. (I know, I was shocked too. Some people actually read this stuff, and one of them even took the time out of their life to write me with a question.)
The sidewalls in question are from a pair of Nokian Freddies Revenz 2.3" studded tires I picked up this winter.
Allman just bought a pair for his new Big Dummy and confirmed that his have the same thing stamped into the side.
Looks like we're going to have to confine our Big Dummy riding to 'designated DH courses only.'
Should be fun
