Tire Balancing Using Road Force Function

To provide a smooth and comfortable ride, proper wheel balancing is necessary. However, conventional wheel balancing methods don’t always have the desired results, which could lead to vibrations and uneven tire wear.
Balance of road force fluctuation aids in that. Why is this even a problem? We talk about it in this Tire Review Continental Tire Garage Studio video.

Road force variation balancing is an advanced technology for wheel balancing that outperforms traditional methods. Using computer models, it assesses a tire’s performance under actual road force pressure when it is deployed on the road. The balancing process is more precise and accurate using this method.

As part of the road force variation balancing procedure, the wheel is spun by a specially designed road force balancer. During this test, a load roller is applied to the wheel to mimic the forces applied by the actual road surface. The machine computes both the standard balance measurement and the balance under road force fluctuation simulation.

The test’s results give a technician guidance on where to search for inconsistencies and how to properly balance the wheel and tire assembly. Some potential remedies include bead massaging the new tire into the rim for a better fit, adding weights to the wheel, and remounting the tire to find a better fit.

In addition to assessing wheel balance, road force variation might reveal other issues that standard balancing procedures could overlook and which could result in incorrect balancing or unwanted vibrations.

Here, two essential parameters for force variation testing are looked at:

Radial Forces, also referred to as Run Out, comes first: Runout refers to issues including out-of-round wheels, rigid tire walls, and uneven tread. These components have the ability to produce vibrations that go beyond simple imbalance.

The second measures the amount that the tire wall bends and is referred to as Lateral Forces. Excessive flex can affect the car’s stability and handling, as well as causing it to pull to one side.

Today’s cars have some pretty astonishing wheel sizes, and it’s likely that your garage has seen its fair share of unusual wheels. Nonetheless, tires with larger wheels and shorter sidewalls may be more vulnerable to vibration effects from the road. Road force balance is a useful tool for fixing those issues.
