Wheel balance is the equal distribution of weight in a wheel assembly with the tire mounted. This is an important factor that affects tire wear and vehicle control. The causes and consequences of axle-end imbalance are complicated; however, it is worth understanding because it costs the trucking industry millions of dollars annually.
Until recently some OTR tire manufacturers would state their tires do not require balancing upon installation, we wrongly assume the entire axle end to be in balance. The tire represents only a percentage of the dynamic rotating mass of a truck or trailer axle-end assembly. When an axle-end is dynamically balanced, tire life can be doubled because it is the tire (even one with perfect static balance) that assumes most of the punishment.
In an out of balance condition, the resonant effect is reflected through the suspension, the frame and the cab right through to the driver’s seat. These are consequences that affect a vehicles ride, handling and suspension life. This will also cause an increase in rolling resistance proportionally with the extent of the out of balance condition, meaning there can be a major hit to fuel economy.
In a few sentences we can see the benefit of balancing the complete axle end. Savings on tires, maintenance and fuel are all realized when balancing with ABC Balancing Beads. ABC’s memory technology stabilizes the beads in place through electrostatic keeping the axle-end in complete balance at all speeds (low speeds, even at a stop), not just hiway speeds reducing rolling resistance that negatively affect fuel economy and have a direct impact on tire wear and maintenance.
