I know there is a couple of threads about going darkside but I haven't noticed anything about double darkside. To keep from changing my front tire twice a year, I am contemplating a Bridgestone Battleaxe BT45 130X70H18 Rear tire for the front of my '08. There is some discussion on another board right now with about 30% of those running this tire on the front having some problems- most notibaly a buzzing. The majority report no problem. Anyone here Double Dark an if so have any problem with this tire?
