My bro had a set of Titan 589's on stock grizz wheels. I offered to "store" them for him while he was moving, that was 4 months ago, they have been on ever since. They seem really heavy to steer but ride pretty decent. But man did they suck up the power, have to use effort to pull the front end off of the ground now. Traction is pretty unbeleivable, or should I say unstoppable, they pull real good. My bro has Dirt Devils on his Grizz now on C's, he seems happy with them. I think I might actually give his tires/wheels back to him and get a set of Bearclaws or maybe Mudlites, haven't decided yet, maybe a set of outlaws..............too many damn decisions.
