IPT 589's weight 29lbs for the front and 32lbs for the rears. The Mud Lite's XL's are about 28lbs for the front and 30lbs for the rear. I have Mud Lites XL's and love them, because I do not ride only in mud, but also hard pack trails and rocks. Both are excellent tires, really come down to looks I would say, but Mud Lite XL's might be abit cheaper $$$.
