magnum+ Tire Balancing Beads – 17.6 lb (8kg) Bulk Tub –

The Verdict

Let’s cut through the marketing. If you’re here, you’re either tired of paying $20 per wheel for stick-on weights that fall off, or you run a shop that balances a lot of tires. The magnum+ 17.6 lb bulk tub is aimed squarely at the second crowd — but it might still make sense for the first, if you think ahead.

What you actually get

The 17.6 lb (8 kg) pail is exactly what it says: a heavy-duty plastic tub filled with ceramic micro-beads. It ships with a measuring cup and a laminated application chart that tells you exactly how many ounces to pour into each tire based on size — from a 155/80R13 up to a 315/75R16. The chart alone is worth a nod; it’s printed clearly and covers passenger cars, light trucks, and Class A motorhomes.

As shown in the product image, the tub has a wide mouth, which is good for scooping but bad for controlled pouring. You’ll want a funnel with a flexible hose to get the beads into the valve stem without making a mess. Plan for that.

Real-world performance

The beads work on a simple principle: they move freely inside the tire and dynamically counterbalance the heavy spot as you drive. In practice, this means you get a smoother ride at highway speeds, and the balance stays consistent as the tire wears — something traditional lead weights can’t do.

Customer feedback lines up with the physics. One verified buyer noted, “Put these in my F-250 after two shops couldn’t get the 35s balanced properly. Vibrations gone at 75 mph — three months and 8,000 miles later, still smooth.” Another reviewer used them on a travel trailer: “No more death wobble at 65. Took 20 minutes per tire and I’ll never go back to weights.”

The TPMS compatibility is legit. The ceramic beads are non-conductive and won’t foul sensors. The 17.6 lb quantity handles a lot of tires — roughly 40 to 60 passenger car tires at the typical 2–4 oz per tire, or about 12–16 large truck tires at 6–8 oz each.

Where it falls short

The biggest issue isn’t the product — it’s the packaging. The pail has no resealable liner. Once you crack the lid, moisture can get in, and these beads will clump if they sit in a humid garage. Buy a desiccant pack or transfer what you don’t use to a sealed container.

Second, this is overkill for a single vehicle. If you own one sedan, you’ll use maybe 8 ounces total. That leaves 17 pounds of beads sitting around, and they don’t last forever once exposed to air. The per-ounce price is excellent, but only if you actually use the volume.

Finally, installation requires a valve core removal tool and a bead injector or a creative funnel setup. This isn’t a five-minute job for beginners. Budget 30–45 minutes per tire the first time.

Who should buy this

Buy it if:

• You run a shop, fleet, or off-road club and balance multiple vehicles regularly
• You own a heavy-duty truck or motorhome with large tires that are hard to balance with weights
• You’re tired of re-balancing after every tire rotation and want a set-and-forget solution

Skip it if:

• You own one passenger car and don’t plan to do this more than once — buy a smaller kit instead
• You’re not comfortable removing valve cores and working with tire tools
• Your primary concern is fuel economy at city speeds — the benefits show most at highway speeds

FAQ

Q: Will these beads damage my TPMS sensors? A: No. The ceramic beads are non-conductive and soft enough that they don’t damage sensors. Multiple reviewers with TPMS-equipped vehicles reported zero issues. Just ensure you install them with the valve stem at the bottom so the beads enter the tire, not the sensor.

Q: How many tires will this tub balance? A: Depends on size. A typical passenger tire needs 2–4 oz, so this tub handles 40–60 tires. A 35-inch truck tire needs 6–8 oz, so roughly 12–16 tires. The included chart is accurate — trust it.

Q: Do the beads settle or clump inside the tire over time? A: No. Once inside a spinning tire, the beads stay loose and mobile. Clumping only happens in the storage tub if moisture gets in — keep the pail sealed with a desiccant pack.

The Verdict

Rating: 4.6/5 — This is a high-quality, effective product for anyone who balances tires in volume. The beads work as advertised, the TPMS compatibility is confirmed, and the price per ounce is hard to beat. The lack of a resealable liner and the sheer bulk knock off half a star, but for the right buyer, this is a solid investment.

Buy it if you have multiple vehicles, a fleet, or you’re a DIYer who hates paying for re-balancing. Skip it if you need just one tire’s worth — buy a smaller pre-measured kit and save the storage headache.
