Just an update..
After about a week of deciding, I went with a set of Falken Wildpeak AT3W's from Discount Tire Direct. No complaints at all with that website. I just recently had the tires put on and personally I think they look great. I have been used to highway tires on the Envoy for over 2 years now and I was fully expecting some decent tire noise. But, to my surprise, they are pretty quiet (for now). I have to really focus to hear the tire noise and with any type of radio playing, you would never know it's there. I'm excited to see how they do in the rain and snow.
