What is the widest tire that you have ran on a XR600. I have dual sported my 95XR600 and am currently running a Dunlop 739 110/100/18. I also have a Supertrapp pipe so I have more clearance to run a wider tire. What do you think would be a good choice for a dual sport rear as well as front tire? I have had good luck in the past with a Kenda Trackmaster front tire on a DR350SE. I am interested in DOT approved tires.
