The mechanic or tire specialist will install your wheel blocks on the wheel balancer one by one. Usually, the device rotates and the machine diagnoses it to find harder areas and measure vibration. The results show if the weight is balanced, and if not, where to apply the additional balancers. The technician then applies steel, aluminium, zinc or lead elements against hard areas. Weights are called balancers. The process usually takes about an hour for all four wheels.
Sometimes the extra weights are enough to correct an unbalanced tire. However, the technician may need to turn the tire on the wheel to restore balance. The reason for this is that the heavier spots (areas) of the wheel and tires can twist, causing more imbalance. It is also necessary to check if the wheel lugs are blocked. They are about 1.5 times heavier than regular lashing nuts, so they can add about 0.5 ounces of weight to the side of the wheel.
There are three main types of tire balancing:
Static balancing involves the application of balancers added to only one line of the tire, called the plane (as if the tire were a disc). This method can be attributed to the methods of the “old school”, which is the easiest to use and useful in cases of mild imbalance. If the tires are out of balance, each tire is placed on vertical support using a spindle tool or balancer. The heavier side will tilt lower towards the ground, indicating that the weight needs to be placed 180 degrees away from it.
In the end, the balancers will only be on one side of the wheel, which is good from an aesthetic point of view. However, if the imbalance is more complex, this method may not be enough.
Dynamic balancing involves weight distribution across the tire (side-to-side, up and down), which allows the wheel to be viewed as a double plane only. Mechanics use modern computer balancers for this procedure. The technician places the wheel assembly on the machine, which then rotates at a specific speed. During tests, the speed is usually between 15-20 km / h. up to 80-100 km / h. While the device is rotating, the machine’s sensors measure any imperfections in the weight.
Spin balancers don’t just show the location of the harder spots if the tires are out of balance. They also measure how much weight your mechanic has to put on to correct the situation. Actually, this is the essence of the adjustment.
In this case, the balancers are on both sides of the wheel and this also provides more precision and balance. In addition, some wheels have a “positive offset”, which means that most of the wheel surface is on the inside. In this case, the outer elements can be behind the face of the wheel, while the inner ones can be on the inside.
Road force balancing is one of the latest technologies that simulate road conditions. In our country, it is not yet very common, but in the USA it is already offered at every second advanced auto station. The car has a large roller that presses on the tire, applying the car’s estimated weight.
This method can determine if the tires are out of balance even in difficult cases. Such machines also have different “tolerances” that allow them to be applicable to different types of vehicles. During the process, sensors read the pressure around the circumference, detecting irregularities.
