Just got the aforementioned yokohama geolander a/t-s's on the truck last night to replace the cooper discovere at-3's that, despite having about a 1/4" of tread left were the most useless truck tire I have ever had in the winter. the yoko's are very impressive int he snow. Almost as good as the silent armors's were but with better handling. I would say the yoko's new handling is right in between the instability of the silent armors (being the worst) and the discoverer at-3's (the best). In my experience of course. It seems instability and great winter traction go hand in hand for obvious reasons.
