These remind me of the markings on Continental DSW tires I used to have. When you could no longer see one of the indicators, they were no longer good for that condition (dry, snow and wet).Can't help with that, but I'm interested in hearing what you find out.
On a similar note, just found this in 6 places on the all weather tires I just bought for the Kia Rondo.
