Thanks cullyguy, first user feedback I have been able to find anywhere. Sounds like they are working as intended. These tires are the successor to the BFG trac-edge which were extremely popular in Europe, swiss alps, etc. but are now discontinued. While they had exceptional snow and ice traction they were also 60,000 mi. plus tires. BFG assures me that these are better than the trac-edges although I think the trac-edges looked better. I think I am headed toward getting some but was looking for first hand experience before shelling out the dough for 7 tires (dually truck plus a spare).
Thanks, Ken
