As far as the dunlop 739AT tire goes I have one but took it off cause it did not do well in the sand. It is an awsome tire for rocky desert riding and it does not wear out quickly. Anybody heard anything good on the Bridgestone 402? The local Tire shop here recommended them - I told them that I was looking for a Maxxis IT. I didn't want to wait mail order, so I think I'm going to try the Bridgestone's this weekend, unless I change my mind to the 756/739AT combo, but the only thing is that I do sand washes. Will this not hook up?
