Over time, due to routine use and wear and tear, wheels often lose this balance.

As a result, the imbalance causes vibrations that are felt through the steering wheel and the cabin, especially when accelerating.

A wheel goes out of balance primarily due to the variation in weight distribution around the wheel or tyre, leading to uneven tire wear.

The effect is magnified as the rotation speed of the tires increases, hence it becomes particularly noticeable during acceleration.

Unbalanced wheels can not only cause discomfort but also lead to premature wear and damage to the car’s suspension and braking systems.

The most significant sign of a potentially unbalanced wheel is a shaking or vibrating sensation that becomes worse with increased speed.

This vibration could get severe enough to cause the steering wheel to shake.

Apart from vibration, other symptoms of an unbalanced wheel are uneven tire wear, decreased fuel efficiency and increased wear on the suspension system.

At high speeds, unbalanced wheels also make the ride less smooth, causing the car to bounce or feel as if it is wobbling.

It is, therefore, essential to get the balance checked and corrected at regular intervals to ensure the overall health of the car.

Even a minimal imbalance can have substantial effects on the car’s performance and durability.

If not balanced properly, the wheels will wobble and vibrate, leading to many driving issues, including safety issues while accelerating.

Regular wheel balancing checks by a professional are crucial to keep your vehicle in optimal condition and reduce the chances of shaky car symptoms.

Remember, by diagnosing and countering unbalanced wheels early on, we can avoid costly repairs, an uncomfortable ride, and most importantly, avoid potential accidents.
