Counteract 4OZ-B12 Centrifugal Force Tire/Wheel Balancing Beads

In this review the Counteract 4OZ-B12 centrifugal force tire balancing beads are evaluated for off-road vehicles, motorcycles and light duty trucks. The bottom line: these glass bead bags are for owners who want a dynamic, self-adjusting balance without repeated shop visits. Installation is simple during tire mounting, and the kit's lifetime balancing action can reduce vibration and even out tire wear, making it a practical choice for drivers focused on smoother ride quality and potential fuel savings on sustained highway speeds.

Key Features

• Automatic balancing: The glass beads shift with centrifugal force to continuously readjust and balance the entire wheel assembly while driving.
• Bag-in-bag application: Small 4oz bead bags are placed inside the tire at mounting, making installation straightforward for technicians or DIYers.
• Complete kit: The 4OZ-B12 kit includes twelve 4oz bead bags plus twelve valve cores and caps so wheels can be prepared without extra purchases.
• Reduced tire wear: The beads reduce rolling resistance and promote more even wear across the tread by balancing forces that cause uneven wear.
• Fuel economy benefits: By reducing resonant suspension effects and improving assembly balance at speeds above 55 mph, the beads can lower fuel consumption over highway runs.
• Reusable, inert material: Made from 99.9% tempered glass spheres that are recyclable and designed to avoid contamination or wheel damage when used as directed.

Who It's For

This solution is well suited for trucks, ATVs, UTVs, motorcycles and light duty trucks where the operator wants a set-and-forget balancing method that adapts as tires wear or conditions change. Fleet operators and off-road enthusiasts who frequently carry loads or encounter rough terrain will appreciate the continuous adjustment and reduced need for conventional static balancing.

Drivers who demand absolute precision for high-speed racing, or those unwilling to modify tire mounting procedures, may prefer conventional static balancing methods. Also, if a vehicle has persistent steering issues unrelated to wheel imbalance, beads alone may not resolve the problem.

Pros & Cons

Pros

• Automatic readjusting balance that works while driving to maintain smoother ride quality.
• Easy to install during tire mounting with the included bag-in-bag bead packs and valve hardware.
• Can extend tire life and reduce rolling resistance, potentially improving fuel economy at highway speeds.
• Constructed from recyclable tempered glass beads that avoid contamination and are reusable.

Cons

• Some users report occasional minor steering vibration, so results can vary by vehicle and tire condition.
• Not a substitute for addressing mechanical issues that cause vibration or alignment problems beyond balance.
