"Wheel weights have been around for many years, but are no longer the only solution for trucks, commercial vehicles and motorcycles. We want you to get the highest possible tire mileage by using our products.

The way we do this is by offering a Dynamic Balancing Solution, a high-density ceramic bead that, when easily installed, continuously balances your tires as you drive. The amount of material will distribute itself in weight and position dependent on the balance requirements of the individual tire.

The result is a smooth, vibration-free ride, derived from our balancing media that is always repositioning itself as the tire wears. If you own a pickup truck, commercial truck, motorhome, RV, tractor trailer, motorcycle, or similar vehicle, and want to get rid of those wheel vibration and tire cupping problems, then you need to move up to Dyna Beads™!"

Snake oil or viable answer? I dunno.
