A few years back I got fed up with the poor traction of the old, hard and worn out tires I had on my 1994 3/4 ton 4x4 Chevy so I went hunting for a nice new set of tires and specifically asked for ones that would give me the best traction on ice and hard packed snow. They showed me a Cooper Discovery M+S tire and it looked like it would be just what the doctor ordered, lots of siping and they could be studded also. I bought a set (with studs) and I found they were all that they said they would be, and I certainly would recommend them. I also have a second set of rims & tires that are better suited for summertime usage.
Oh, BTW, these are a true winter/snow tire, complete with emblem.
