Why is It Essential to Balance Tires Every Time They Are Mounted and Dismounted?
Tires and wheels are manufactured with the exterior being divided into sections with varying weights. Each time a tire is mounted or dismounted, the position of these lighter or heavier sections changes relative to the wheel. To ensure the tire and wheel combination performs optimally, it is crucial to balance the tire every time it undergoes this process. Ignoring tire balance can result in noticeable vibrations during driving, excessive wear on the suspension and steering components, and, in worst-case scenarios, a loss of control. This article delves into the importance of tire balancing and the consequences of neglecting this step.
The Importance of Tire Balance
A tire must be balanced properly to ensure smooth and safe driving. An imbalance can occur due to manufacturing tolerances. Even a slight imbalance, as little as 1/4 oz, can be felt by the driver, especially in race cars. While most drivers may not notice such a minimal imbalance, it can still cause vibrations and uneven tire wear. The wheel itself can also be imbalanced, sometimes by the same amount. When both the tire and wheel are imbalanced, the combined imbalance can significantly affect the vehicle's performance, causing a noticeable front wheel shake or rear wheel vibration.
Consequences of Ignoring Tire Balance
Without proper balancing, the tire and wheel combination can become "out of true," resulting in vibrations that propagate throughout the vehicle. This can lead to uncomfortable steering wheel vibrations and excessive wear on the suspension and steering linkages. The impact on the driving experience and vehicle performance can be significant. To illustrate this, one can perform a simple test by asking the tire technician to not balance the wheel during the next tyre change. Not doing so will likely result in a noticeable difference and a return to balancing the wheel, as seen by experienced drivers.
Tire Balance Process and Best Practices
The process of balancing a tire involves adding counterweights to the rim of the wheel to offset any unevenness. This is typically done on a balancing machine that can quickly detect and correct the imbalance. Regular tire balancing is recommended for both new and used tires. However, significant wear on the removed tires, particularly noticeable on the outside faces of the tread, may indicate the need for a wheel alignment in addition to balancing.
Conclusion
In summary, neglecting to balance a tire every time it is mounted or dismounted is not recommended. The potential consequences, including vibrations, wear, and loss of control, make it an essential part of tire maintenance. Proper tire balance ensures a smooth, safe, and comfortable driving experience. Drivers who have experienced the stark difference between balanced and unbalanced tires can attest to the importance of this step.
Frequently Asked Questions
1. How often should tires be balanced?
It is recommended to balance tires every time they are mounted or dismounted, especially when experiencing significant wear on the outside faces of the tread.
2. Can an unbalanced tire cause loss of control?
Yes, if the tire becomes significantly unbalanced, it can lead to steering vibrations and excessive wear on the suspension and steering linkages, potentially resulting in a loss of control.
3. Is there a noticeable difference when a tire is unbalanced?
Yes, even a small imbalance, such as 1/4 oz, can be noticeable, particularly in situations where precision is required, like in race cars. Most drivers, however, may not feel the difference but can still experience a less smooth and comfortable ride.
