I have been using dynabeads then airsoft BBs for the last 30+ tires
most of my prevous bike had nice oz, marchesini cast and forged wheels. they usually take a quarter oz to balance. so beads would work fine
my zrx has some HEAVY wheels which took 1.5 oz to balance without tires as I found out for the first time last week. I mounted a used angel (pirelli) but the paint spot faded so I did not clock and just put in my usually amount of BBs. got a vibe above 80mph so I balanced it the old fashion way.
