Have had these tires for many of years. They are excellent if you have a 400CC or less quad. I have friends that are on their 10th trip to the dunes on these and are still looking great. If you got a banshee, 450, or raptor, I wouldn't get these, but for lower powered machines they are great. I am faster with these than a set of more aggressive paddles. Installed on a LTZ400.
