Well to start the tires are completely different.. the 589 being a more all around/ mud tire.. imo the mudzilla is alot more toward the mud riding, they dont ride that bad. however, the mudzilas are a pretty heavy tire. I would not buy these tires new but, i would trade for them... what size are they?
They are 27's I kinda thought they were heavy. I don't think there would be a problem turning them with the 800 but it might be hard on a stock clutch.
