I finally have the extra cash laying around to get my wheel and tire package. I was going to get 27's but i think 28's will be a better fit for me. I'm probably going to regret not getting the bighorns but i see them all the time and they just don't impress me that much. Ya they are durable but they look horrible in mud and on wet ground/hills. I did a lot of research and the biggest complaint from people who bough 27's was they didn't buy 28's and the biggest complaint from the people who bought 28's was they didn't buy 30's. I think 30 would be rediculous. I do mud some but i do a lot of other riding as well. I think 30's would be awkward on the hill climbs i do. Is the only reason they are saying that should of went 30's is because of the mud or do these tires just run that small?
