Haven't owned a set myself. I have wheeled with a guy who has them. Before going out I checked them out. If you just grab one of the lugs you can feel how soft it is. You can literally feel how "grippy" they are. Watching him he barely gave gas over obsticles. It's been said that pitbull rockers are the stickiest tires you can get short of competition tires. Rockers have been getting nothing but great reviews if you look on the internet and if I had the money to buy new I would certainly be picking up a set of pitbull rockers.
