wj, the Kumho'* are excellent in the snow, ice, slush, and rain I have right now, and they're still covered in mold release from the factory. They are, as advertised, an all-season tire with better than average summer handling.
FWIW, I hear more bad reviews about the RSA'* on this Forum than anywhere. There was one posted today.
The wranglers are the worst tires I ever had on either of my full-size Chevy'* or my Suburban. Horrible road noise and very 'selective' traction.
But that'* getting off-topic.
The point is that I carefully researched these tires before I bought them, and I went to two different tire shops for them (for very specific reasons). Bear in mind, the guys at the shop I bought the Kumho'* from have a great deal of respect for me, and know me very well, as well as my driving habits. They have a pic of the Zilla in full-smoke burnout mode on their wall. They did my slicks for me. They pointed out the Kumho'* immediately when I told them what I wanted, and they suggest them to MANY people here that drive in the same conditions I do, but want a little better summer traction as well.
