Do you remove old tyre wheel weight when balancing tires
When balancing tires, it is usually necessary to remove the old wheel balance weights.
I. Reasons
1.Accuracy considerations
The old wheel balance weights were installed before to balance the tires. However, as the tires are used, the wear and repair of the tires may change their original balance state. If the old wheel balance weights are not removed, the new balance measurement and adjustment will be disturbed. For example, the position and weight of the old wheel balance weights may no longer meet the actual balance requirements of the current tires. Suppose the previous wheel balance weights were added because there was a slight material unevenness in a certain part of the tire, but after a period of use, the wear of the tires caused the situation of this uneven point to change, and the old wheel balance weights would cause the new balance test data to be inaccurate.
2.Avoid overbalancing
Keeping the old wheel balance weights may cause overbalancing problems. Tire balancing is a precise process that requires accurate determination of the imbalance point and the required wheel balance weights. If the old wheel balance weights are not removed, the newly added wheel balance weights plus the old wheel balance weights may cause the tire’s balance state to exceed the normal range. This is like a balance. There are already some weights on the balance to balance the object. However, if the old wheel weights are not removed and new wheel balance weights are added, it is easy to make the balance lose balance, causing the vehicle to shake and other abnormal conditions during driving.
3. Accurately locate the imbalance point
Removing the old wheel balance weights allows the balancing machine to more accurately detect the imbalance position and degree of the tire. The balancing machine detects the imbalance condition by rotating the tire, and the presence of the old wheel balance weights will interfere with this detection process. For example, some high-precision balancing machines use sensors to detect the tiny vibrations and centrifugal force changes of the tire to determine the imbalance point. The old wheel balance weights may cover or change these signals, making it impossible for technicians to accurately find the true imbalance position.
