I have had these tires for three months now and I am impressed. These are a huge improvement over the stock PXTs (2006 stock Polaris 500 tires). They are very good in mud, sand and hard packed terrain to include rocks. I have had bearclaws and these handle much better and are night and day better in the sand and ride quality (equal in mud). These tires are top notch and I highly recomend them as a top of the line all around tire. The ITP ATR is better in thick mud but I prefer an incredible all around tire.
