Submitted my vote for the Duratracs. I absolutely LOVE mine - by far the best all around tires I've ever owned. They do great on the highway and are not that noisy at all, but are as sure footed as a mountain goat on sand, dirt, mud and snow.
You may recall that we got a freak snowstorm up here in the Inland Empire right before New Year's Eve, and I spent the entire evening/night driving around filming the storm for the local TV news. There was over 8 inches that fell in Wildomar and closer to 10 inches that fell in a hilly area known as La Cresta. I was running circles around every single other stuck vehicle, including tow trucks and fire engines. Never even broke a wheel loose for a split second.
