Monster- that is about what I experienced. Did the Maxxis chunk more than the Dunlop? Ours did. (some high desert-mostly Baja) The Maxxis is tougher but under hard conditions does chunk larger chunks. However it does hold up better than the Dunlop. I did a 50 mile high speed (top 93mph) run across very rocky southern Nevada terrain to see what would happen. With the Dunlop it chunks but wears more evenly. The Maxxis holds up better and longer but chunks larger pieces. Given what I've seen I'll use the Maxxis for more rocky terrain and save the Dunlop for a bit less rocky ride. FYI, I ride hard and aggresive so you and/or others may not get the same results. As always, it depends... Oh yea, I had a a buddy in a helicopter follw me. We will try and get some video on-line soon??
