This is my second pair. I run them on my Polaris Ranger XP900 and got 5,500 miles out of the first set and my rears are still 1/3 tread. The 8 ply rating is what I was after as i run a lot of pastures with thorns and also run rocky trails in the Colorado Rockies. They are great in mud, snow and rock, the only downside is that they are louder than stock tires or the less aggressive ones on the highway when running 40 mph or faster but I do not travel a lot on the highways.
