They are a great tire. Very nice tread pattern and look great due to the aggressive shoulder. Snow traction is good. A bit louder then some, but not very, most wont even notice. Im just picky about things like that.
Just to give some more input....I've had these cooper zeon LTZ's for a few months now and almost 10k miles, they are the best tire I've ever had on my trucks. I used to run pirelli scorpions and the were great, these coopers are even better. I've never noticed any more noise with these than I did with the stock good years, even at 70 and 80 mph. I was amazed at how quiet they are. They wear great, look awesome, and although I can't comment on snow or mud capabilities as my truck pretty much stays on road, they do everything they are supposed to do.
