In reply to Azryael :
I have the beads in my Armada tires and the snow tires on my Buick. So far so good, once in a while I feel like they take a few seconds to find balance but again it could be the road. Both cars run smooth down the highway.
I feel like when I back across the parking lot to clock out there is a feeling of a bad tire but never any where else, it's probably the parking lot.
Successfully removed some 22" tires from some Suburban wheels. So far the big ones are the easiest, they almost just fall off.
As a side, what are these beads being mentioned? I know of Dyna-Beads for big semi's and motorcycles. I always wondered if I could get my tires standard balanced then chuck an ounce or two for that "cheap roadforce balanced" feel?
Falken RT660's 225/45/15 on 15 x 7 wheels is not much fun. I got them but it takes a different approach, no lube to keep the bead in place. Maybe it was due to the powder coat but it took all the air pressure to seat the bead.

Once in a while the balance beads seem to take a mile or two to settle in. Not very often, maybe one out of 50-100 times when accelerating to highway speeds.
