For a good riding, all out mud tire, I would reccomend the 27" Bi/Tri Claw Magnums. I have them on my Bear and they do really well in the mud, ride great on hardpack and didn't effect my power too much.

 

I have no complaints with my 27" Mudbugs. My Kodiak turns them very well in high in all but the deepest mud. I have a place back in VA to test my power mods this Spring to see if it helped. By the speed I have noticed and being able to spin the mudbugs on concret I would say it would turn them. The Mudbugs without spacer or lift kit will just touch the brake assembly cover on the right side and the tranny breather tube on the left side. Its not very noticeable at all and will not damage anything. Im not even worried about it. You have to turn the tires to the farthest point to make the just barely touch. The 27" mudbugs are a light tire. 22lbs for the 10"wide and 28lbs for the 12"wide. I weighed them before I had them mounted. The other tires I considered were the 589s and bi/tri claws. For me it came down to price and buying at a local tire store. I believe I paid $310 maybe $313 out the door and that included mounting.
