DBond, sorry for not responding to you sooner, been out of the loop for a while. The Cooper ST's worked OK in the snow and mud and good on wet surfaces when new. Had no problems on the drive to Montana and back. However on ice they are not as good as I had hoped. With a heavy vehicle they tend to slip a great deal. More factory siping (sp?) would help. A local dealer wanted to charge me an additional fee to "sipe" the tires. Good tread wear. They do make the truck handle better on and off pavement. I would like to see them made in a LT 285/70/17 E size though.
