I've been using BBs in tubeless tires on my car, truck, GoldWing, two Honda CB 750C's, and a couple of trailers. I weigh them and use the same weight recommended for the tire on Dyna Bead's charts.
One nice thing about the beads in a tube type tire, you can mount the tire and install the beads later, or, have a shop install the beads after you mount the tire. AND NO UGLY WHEEL WEIGHTS ON YOUR PRETTY RIMS.
I buy some tires at Walmart, but they will NEVER mount or balance a tire for me ever again. That way I can clean the bead area on the rim, use a much better quality valve stem, and balance the tire with BB's myself. So, no more inferior mounting from Walmart with slow leaks that have to be constantly checked or removed and re-mounted.
