I purchased this tire in 30x9x14 and so far I am absolutely thrilled. I have about 300 miles on them so far and I haven't found any situation where I've been disappointed with them on my grizzly 700. They don't seem to rob power, they do fine in sugar sand and on hard dirt roads. Deep dry or stickey mud is no problem either. I ride way more then the avarage rider, 500 plus miles a month so I am interested to see how they wear. So far they are fantastic and I would buy them again.
