These tire balancing beads have earned their reputation over the years as a top-quality internal balancing compound that is completely safe for the tires and their components. There’s not a single balancing job that can’t be done with MAGNUM , no matter the size or type of tire – truck and off-road tires, for summer and winter – you can trust the original internal balancing bead brand that’s been on the market for more than 25 years. Just toss the bag of beads in the tire and mount it as usual. They are free of silica-based coating. They are also both recyclable and reusable. They will outlast your tires. Not only are they timesaving, but they are also a hassle-free tire balancing solution. This item requires no machines and no rebalancing. 12 individually packaged bags of tire balancing beads are included in the case. They are big enough to never obstruct a valve core, so there is no need to install a special valve core. This product is compatible with standard tire valves, tire-pressure monitoring system (TPMS), and truck tires. It is also 100% made of tempered glass which means that it cannot break, disintegrate, absorb moisture, freeze, or stick together. The MAGNUM packaging as well as the tire balancing beads are recyclable and eco-friendly. Dynamic internal balancing will eliminate vibrations caused by any heavy spots, promote consistent tread wear in addition to longevity of the tire, and improve gas mileage.
