i had 27" on my rubicon and i loved them. IMO i thought that they went great in mud, not as good as outlaws but they did really good. they were really heavy, i cant remember the weights but i think it was aboud 27 lbs. the hight of my 27s were 26.5 with about 3 lbs of air in them. i would get them again, i was very happy with them. they also wore really good.
