I've had them on my truck for about 10 months now and already put about 19,000 miles on them! They are really good tires. Great in the mud.. and snow. The only problem I had with them is when it's raining out. They spin VERY easy on wet pavement, even though they have the siping blocks. They wear out about as fast as any aggresive off road tire would. Also, they're not as noisy going down the road as I expected. All around, a great tire.
