Here is a good read on bead balancing. Unforunately, X100's do not seem to fit the application as do big trucks and motorcycles. Even my Ram1500 (20" wheels) does not seem to qualify.
If one does have a qualifying application,they may want to check out Centramatic wheel balancers on Amazon. (more expensive, but not as messy)
