Counteract 6OZ-B4 centrifugal tire balancing beads are small tempered-glass spheres in four sealed bags that automatically balance off-road and light-duty truck wheels throughout their service life.
These premeasured, bag-in-bag balance bead kits (four 6 oz bags plus valve caps and cores) are designed to be installed inside tubeless tires during mounting. Once the tire spins, the beads migrate to the light spots and redistribute themselves using centrifugal force so the entire wheel assembly gains continuous micro-balancing without machine weights. They’re reusable, non-toxic glass spheres engineered for on- and off-road driving where traditional static balancing can be quickly upset by terrain, heavy loads, or frequent tire rotations.
The beads move freely inside the tire and use centrifugal force to settle at points that correct imbalance as speed changes. They automatically adapt to changes such as added cargo, tire wear, or slight damage so the wheel assembly remains dynamically balanced without reweighting by hand.
Counteract beads are made from 99.9% tempered glass and installed beside the tire inside the wheel; they will not contact the wheel face or bead seats when installed properly. The product is marketed to avoid contamination and not to interfere with tire structure, and Counteract states their beads do not void tire or wheel warranties.
Installation is performed when mounting tires: each prefilled bag is placed inside the tire before seating the bead. The kit arrives ready to use with four 6 oz bead bags and hardware to reseal valves, simplifying fitment for most off-road and light-duty truck tires.
Beads are particularly helpful for vehicles that experience frequent load shifts, rough terrain, or high-speed travel where static balance often breaks down. They are commonly used on off-road rigs, ATVs, light trucks, and motorcycles that need ongoing balancing through varied operating conditions.
Who is this for: The Counteract 6OZ-B4 kit is aimed at owners of off-road vehicles, light-duty trucks, ATVs, and riders who want a maintenance-free way to maintain wheel balance without repeated machine balancing. It suits fleets, weekend adventurers, and anyone who replaces tires or rotates wheels often and seeks stable ride quality, reduced vibration, and potential fuel economy improvements at sustained speeds. Install at the time of tire mounting for the best performance and keep the provided valve caps and cores for sealing and reuse.
Q: Can I install the beads myself when mounting tires?
A: Yes. Place a sealed bead bag inside each tubeless tire during mounting, then reseal the valve using the included cores and caps.
Q: Do the beads work on both on-road and off-road tires?
A: They work on most tubeless tires for off-road, highway, and light-duty truck use where continuous dynamic balancing is desired.
