In short
Balancing distributes the mass of the wheel to reduce vibration, alignment adjusts the angles of the wheels relative to the vehicle, and rotation changes tire positions for more even wear where permitted. Before the work, the condition of the tires, rims, suspension and steering should be checked.
Balancing deals with the wheel as it spins
A small imbalance becomes noticeable with speed and can cause vibration in the steering wheel, seat or body. Weights on the rim correct the mass distribution of the wheel and tire assembly.
Vibration can also come from a deformed tire, a rim, deposits or a mechanical part, so the machine and an inspection go together.
Alignment sets how the wheels stand
The angles affect direction, steering wheel position and wear. Hitting a pothole or curb, or work on the suspension, can change them, but play and damage should be dealt with before adjusting.
A printed before-and-after result helps you see what was measured and corrected.
Rotation tries to even out wear
The front and rear axles do not always wear tires at the same rate. Changing positions can extend the even use of a set when the sizes, direction of rotation and construction allow it.
Vehicles with different front and rear sizes or with directional tires have limited rotation patterns.
Use the symptom to start the conversation
Say whether the steering wheel or the seat shakes, at what speed, whether the car pulls and how the tires are wearing. Do not order balancing alone in advance if the problem started after an impact and damage is visible.

Key points
Three things to remember
- 01
Vibration at a certain speed often points to the wheel, but a check confirms the cause.
- 02
Alignment is done when the relevant parts are sound.
- 03
Rotation must respect the direction, sizes and manufacturer's recommendation.
FAQ
Straight answers
Are wheels balanced at every tire change?
Balance is checked after a tire is fitted and when there is vibration or a change. Practice depends on the type of change and the condition of the set.
Does alignment fix steering wheel vibration?
Not necessarily. Vibration at speed is often related to the wheel, but the cause can be something else. Alignment primarily adjusts angles.
Can all tires be rotated crosswise?
No. The direction, sizes, position and manufacturer's recommendation determine the permitted pattern.
