Yes, the old Nordics (Nordic WinterTrac and Nordic IceTrac) were made by Michelin-Uniroyal-Goodrich. The WinterTrac being an exact copy of the BFG Winter Slalom except for the branding, and the IceTrac based on a now obsolete Euro market tire sold under the Michelin umbrella as a "Kelber."
The new Nordics (the two have been replaced by one) are Good-Year, based on their Euro market UltraGrip 500.
Going back to the 2 versus 4 winter tire non-debate, if anyone is familiar with the history behind the snowflake and mountain symbol now put on true winter tires, they will know it stems from a serious accident that occured on the highway between Whistler and Vancouver many years ago. A young lady driving back home in a storm was killed. On her FWD car were two winter tires in the front and two all-season tires in the back. Guess what accident investigators determined? Her loss of control of the car is directly attributed to her tire set up. Out of that report came the recommendation for the new symbol so people could tell a true winter tire from a non-winter tire, and along with that came continued recommendations that winter tires only be installed in sets of 4, regardless of drivetrain (FWD, RWD, AWD or 4WD). Don't believe me? Google it for yourself.
