If your going to be doing mainly trails and light mud, defineatly take a look at the Mud Lite XTR, the 14inch tire is the best for trails and if you want it more mudwise go with the 12 inch, best tire for all around and great in mud, not as good as an outlaw or anything but it gets the job done. You said you liek the 589's their a nice tire but a guy I ride with and we do trails and mud basicaly, from alot of trail riding he blew the ball joints on the front end of his grizzly because of too much vibration.
