The wheel is not balanced: the causes of the malfunction and possible solutions
First of all, if the wheel is not balanced, you should pay attention to the condition of the disk. As a result of driving on rough roads, there is a risk of dents. Such defects directly affect the spread of the centers of mass.
Wheel balancing directly affects the performance of the car. The intensity of tire wear and the performance of suspension elements also depend on this. In addition, an unbalanced tire causes steering wheel vibration and discomfort.
To avoid negative consequences, manufacturers recommend performing the procedure with each change of rubber. Sometimes there are situations when the wheel is not balanced.
After analyzing the possible causes, taking into account the opinions of auto experts, we will figure out what factors influence. And also what needs to be done if the wheel is not balanced the first time.
Main sources of failure
A car tire has a heterogeneous composition. The tire is made from a plurality of alternate layers of rubber, nylon and metal fibers. Therefore, it is difficult to achieve an exact center of mass during the manufacturing process. At speeds above 60 km / h, a beating may occur, strongly giving off to the suspension and steering.
As a rule, balancing on a special stand leads to the alignment of the centers of mass and eliminates a possible problem. Sometimes it is impossible to fix the problem the first time.
Balancing stand
The most common reasons for a wheel not being balanced can be:
- deformation of the rim;
- ingress of a foreign object or water into the tire;
- uncalibrated balancing machine;
- disc unevenness.
These moments, imperceptible at first glance, play an important role in ensuring the performance of the car.
How to avoid
To exclude factors in which the wheel is not balanced, you need:
- choose only proven service stations and car services;
- install tires on wheels without obvious signs of wear and deformation;
- pay attention to the qualifications of the staff.

By adhering to these simple rules, you can avoid the problems that arise when tires fail.
The first time
First of all, if the wheel is not balanced, you should pay attention to the condition of the disk. As a result of driving on rough roads, there is a risk of dents. Such defects directly affect the spread of the centers of mass. To eliminate such a defect, before starting balancing, the disk must be aligned on a special rolling machine.
Another circumstance that affects the fact that the tires are not balanced is the uneven wear of the brake disc. In the process of stopping, when the calipers come into contact with this part, differences in thickness can cause severe runout. Therefore, the driver has a feeling of an unbalanced tire.
Uneven brake disc wear
The machine tool must be periodically checked for faults and calibrated. Otherwise, there is a difference in the direction of centrifugal forces. A constant mass difference will be recorded on the machine, and each time in a different place, which is why the wheel is not balanced the first time.
On conventional stands, a universal cone is used to install the disk; wear of the part also affects the reliability of the indicators. Some service stations use a hub that imitates a hub for more accurate measurements. In this case, balancing is carried out not in the center of the disk, but along the wheel mounting holes.
The speed of the process depends on the qualifications of the staff. And knowing the procedure will allow you to quickly decide what to do if the wheel is not balanced, as well as maintain confidence in the correctness of the work.
