Best Uses
31700 miles in 2 years and tread was near the wear bars and most of my driving is highway. On my monthly drive home blew a tire at 70 mph on a smooth streach of highway in 117 degree temp, replaced the whole set for another $1000 bucks.

Best Uses
As an ag chemical salesman/ PCA, I spend about 40% of my driving time on dirt roads, in sometimes wet and muddy conditions. These tires have handled everything I have thrown at them. I had them in snow one time this winter, and they performed like a champ in those conditions as well. I have them installed in a 2013 GMC Sierra 1500 4x4 Crew Cab, and have had them 3 months. They are well mannered on pavement, and great off road. I have owned Goodyear Wranglers previously on this truck, and these tires outperform the Wranglers in just about every way. Very happy I chose these tires. I highly recommend these tires to anyone who needs a good on and off road tire.
How long have you owned it:
One-to-three months
Bottom Line
Yes, I would recommend this to a friend.

Happy with my tires
The Grip Was Amazing
A little noisy
Best Uses
I've been driving a large SUV for 11 years and have to say this is the best tire purchase I've made. I go through tire pretty quickly but I've had these for 2 years and over 30 K miles and they almost look new. Now mind you I regularly rotate them and check the pressure at every oil change but these are great tires!
