Just a thought, but I would say that Bighorns and Mudzilla's are pretty much at opposite ends of the tire world. If you are looking for a down the center tire good for trail/general riding but still good in the mud, take a look at the Carlisle ACT XLR's. I have a set of them and they ride better than stock, go through mud that you would have to see to believe, and are available in sizes up to 27". My 26's fit on without a lift and only rub on really hard cornering downhill or landing. I really like them.
