A vehicle that circulates with poorly balanced wheels suffers a series of vibrations uncomfortable for the driver. In addition to the discomfort they cause, they harm certain vehicle components. These vibrations appear and disappear depending on the speed at which they circulate.

To understand the process of balancing the wheels, it is necessary to see the types of balancing that are carried out, differentiating between static and dynamic balancing.

What is the process of balancing the wheels based on?
Balancing the wheels is done to avoid vibrations during driving and the damage they can cause to the vehicle. With the balance, Dynamic Balancing Services eliminate the harmful moments of inertia generated on the wheel’s axis. These moments produce vibrations and forces on other vehicle systems that can cause wear and fatigue.

Types of wheel balancing
When balancing the wheels, they adjust the weights of the tire-rim system so that it is in balance. This balance has to be static and dynamic.

Statically balanced or balanced on a plane:
The wheel is placed on an axis supported by parallel bars and allowed to rotate by itself until it reaches equilibrium. The part of the wheel with more weight is located in the lower part and the lightest in the upper part. To compensate for this imbalance, they must place a counterweight on each side of the wheel and in the opposite direction to the imbalance, or you can place a counterweight in the centre of the wheel.

As you can see in this process, they compensate for the unbalance of the wheel when it reaches equilibrium in its plane, that is, in a plane that contains it and is perpendicular to the axis. The compensation is carried out when the wheel reaches static equilibrium. This type of balancing is mainly used to balance motorcycle wheels because the width/diameter ratio of the wheel is less than that of a car, and Dynamic Balancing has less influence.

Despite this, it is always advisable to carry out both types of balancing, especially on car wheels and those with larger widths where the wheel can be balanced statically but not dynamically.

Dynamically balanced or balanced in two planes:
Dynamic unbalance appears when the wheel is in motion. That is why you cannot appreciate it previously, and the wheel must be placed on a wheel balancing machine.

With this balance, Dynamic Balancing Companies work in two planes, the wheel (vertical) and the wheel axis (horizontal). In this case, if the wheel is not in equilibrium and is moving on an axis, torques are produced that tend to move the wheel out of its (vertical) plane, producing oscillations or what is known as “wheel wobble”. Placing the wheel on the wheel balancer and “throwing” it, you will able to know where you must place the counterweights to correct the imbalances.

Another way to do this type of balancing is with the wheels mounted on the vehicle. This balancing is done with a mounted wheel balancer.

Before starting, make sure that the vehicle’s bearings and suspensions are in perfect condition since this type of balancing can be difficult or impossible if there are defects. Another step to be carried out beforehand is to check that the wheel is correctly mounted on the vehicle and that the rim is not deformed. If the wheel is deformed, it will cause discomfort and vibration even after perfect balancing.

Once they are ready to balance, Dynamic Balancing denver will place the transducers on the wheel to start balancing and follow the indications that the balancer manufacturer marks us. In the case of balancing the drive wheels, both wheels must always be lifted in such a way that the differential is not damaged. It is advisable to use two transducers.

Current wheel balancers detect and correct both imbalances and work with all types of wheels. However, it must be said that the precision in the balance varies depending on the tolerances of the manufacturing process of the wheel balancers. There are cases where even experienced and sensitive drivers still feel residual vibrations after balancing. This is because only the most advanced models work with precisions of 0.5 g or less and can completely eliminate all vibrations.

Most drivers are not able to feel these small residual vibrations as they usually appear at speeds above the established traffic limits. Performing a correct wheel balance is essential to avoid vibrations, premature tire wear and other damage to vehicle components.
