Counteract Tire Balancing Beads Kit (4) 10oz Bags with Valve Cores & Caps — Reusable Tempered Glass, Auto/Off‑Road

Counteract 10OZ-B4 is a centrifugal tire balancing bead kit that automatically balances off-road, motorcycle and light-duty truck tires using reusable tempered glass beads.

These pre-measured, bagged glass beads mount inside the tire to create a continuously self-adjusting balance as the wheel spins. The system is passive—no mechanical parts, sensors, or weights—so it maintains even distribution through changing speeds and loads. This kit includes four 10 oz bead bags plus four valve cores and caps for a simple install when mounting new tires or re-mounting existing ones.

How do these beads keep tires balanced while driving?

Balancing beads shift under centrifugal force to align opposite heavy spots, delivering a dynamic, evenly distributed rotary mass. As speed increases the beads find equilibrium around the rim, correcting imbalances without manual rebalancing. This action continues whenever the wheel turns, compensating for changes in load and road conditions.

• Beads move inside tire to counteract heavy spots during rotation
• Automatic re-distribution works at operating speeds, no tools needed
• Reusable tempered glass spheres resist degradation and contamination

Will these beads extend my tires' usable life?

The beads reduce irregular wear by evening out the contact patch across the tread, which helps tires wear more uniformly over time. With fewer vibration-induced hot spots and less uneven shoulder wear, you can expect more consistent performance throughout a tire’s life. Proper inflation and alignment remain essential for optimal longevity.

• Promotes uniform tread wear to help maximize mileage
• Reduces vibration that can accelerate uneven wear patterns
• Works alongside routine maintenance like rotation and alignment

How easy is installation and what’s included in the kit?

The bag-in-bag design makes installation fast when tires are mounted: drop each sealed bead sachet into the tire through the valve stem hole or during mounting, then inflate and seat the bead. No adhesives or additional hardware are required. This kit supplies everything needed for four tires so you can balance an axle or full vehicle in one session.

• Contains four 10 oz pre-measured bead bags ready for tire mounting
• Includes four valve cores and matching caps for a complete install
• Simple drop-in application during tire mounting or service

Are these beads safe for wheels and the environment?

Counteract beads are manufactured from 99.9% tempered glass spheres designed to be inert and non-abrasive inside the tire. The bagged format prevents loose beads from contacting wheel finishes, and the glass material is recyclable and reusable. Counteract specifies that use does not void tire or wheel warranties, but always follow manufacturer guidance for your specific wheels and tires.

• Tempered glass beads are non-reactive and recyclable
• Bag-in-bag prevents contamination and protects wheel finish
• Manufacturer states beads do not void tire or wheel warranties

Who this kit is for: The 10OZ-B4 Counteract set is aimed at off-road enthusiasts, light-duty truck owners, and riders who want a maintenance-free way to reduce vibration and promote even tire wear. If you or your shop regularly mounts tires for pickups, SUVs, ATVs or motorcycles and prefer a passive, reusable balancing solution, this four-bag kit with valve cores and caps provides a convenient, ready-to-install option.
