Normally, people notice the wheels on the wheel wheels appear rectangular cylinder, small cylinder paste inside the tray or close on the edge of the edge of the wheel. There are only two kinds of lead-free racks, which come in many different sizes depending on the weight (gram).

It is very important to install lead scales. Because in the process of manufacturing wheels, the accuracy is not absolute, there are errors though small and for tires (tires) too. When the combination of wheels and tires definitely cause errors. This error will cause imbalance, stability when the wheel works, especially at high speed. So, people usually put in the machine (dynamic balance) to check the stability of the wheel (tires and tires) and the lead that will work to balance when the wheels work. Depending on the error of the wheel, there will be lead with a weight of 5, 10, 15 or 20 grams.

In fact, this dynamic balance registers the oscillation cycle parameters of the wheel hub pressure according to the rotation to determine the correct position and mass of the lead to be mounted.

Thanks to modern technologies, tires (cars, motorbikes) have improved over the past decades, but they still need to be balanced in order to minimize the wear on the steering system components. and suspension. Wheel balance includes measuring the center of gravity of the wheel (wheel and tire) and adding the weight needed to move the focus to its proper position.

In addition, when operating at high speed, the error of many will cause all four wheels to lose balance to create vibration causes the phenomenon of the wheel wear irregular. More serious will affect the bearings, wheel axles, rickshaws, the joints will be deflated, causing deformation or wear of the brace system and destroy the rotating parts.

The center of gravity is considered to be the total weight of the wheel. In theory, if considered wheels, tires are ideal, the center of the middle of the cake. But in fact, the wheels and tires are not completely round, material is not uniform and shape makes the center deviation from the wheel rotation. When spinning, centrifugal inertia forces the wheel to shake around its axis causing vibration. The addition of lead-weight balance helps to adjust the center of the wheel back to the rotary axis to eliminate centrifugal inertia.

As advised, we should balance the wheels when replacing the tire (new), operating after 10,000 km or periodically from 4 to 7 months.
