It's not hard to do. Been doing it myself for years.
I've used actual ceramic beads intended for it and also Airsoft BB's. The BB's don't work as well because they are physically larger but if the tires are very true (mine were the Michelin XL's that are famous for being vibe free) then they will work. Dunno on Pitbull's "roundness". If you can break the bead you can just dump them in and reseat the tire. Couple of the companies even sell the beads in packets that you dump into the tire, reseat, and then the first couple spins rip the bag open and viola, all done.
Oh yeah, ever do anything on the axles? See you're still 6 lug and autolocking hubs up front.
