“I just changed the tire, but it bubbles at high speed…”
It is not uncommon for Volkswagen to have a strong vibration immediately after replacement.
At high speeds, slight misalignments and differences in assembly can manifest as large shaking, so it is important to correctly isolate the cause.
In this article, we will explain in an easy-to-understand manner the causes of vibration that are likely to occur after changing tires and where to check.
If you have just replaced it and feel that something is strange, please refer to it.

Common symptoms
- It was normal before changing tires
- Sudden boom at 80-120 km/h
- The steering wheel trembles finely
- Not stable at high-speed merging
- Almost no feeling at low speeds
- I also rotated at the same time as changing tires
There are four main causes (by structure)
- Wheel balance misalignment (most common immediately after replacement)
- Lack of centering (poor adhesion to the hub)
- Shaking due to individual differences in tires and assembly direction
- Cases where the effect of uneven wear has moved to the “front wheel side”
Cause (1): Wheel balance misalignment (the most likely representative cause)
When does it happen?
- Immediately after replacement, it shakes only at high speed.
- Vibration peaks around 80-100 km/h
- Particularly large front wheel shaking
Why do I have symptoms?
Even new tires will vibrate at high speeds if the balance is weak or the weight is improper.
- Mispasting of the balance weight
- Machine measurement error
- Misalignment of nut tightening position
VW has a severe undercarriage, so even a few grams of deviation can manifest itself as vibration.
If left unattended?
- Steering wheel vibration worsens
- Uneven tire wear progresses
- Load on the undercarriage and steering system
Cause (2): Lack of centering (slight deviation of bolting)
When does it happen?
- Strong shaking only after replacement
- Changed the wheel to an external product
- There is a lot of shaking on only one side
Why do I have symptoms?
VW is severe for hub diameter, and if the wheel is not fully centered, it will bulge at high speed.
- Lack of hubring (for external wheels)
- Bias in the tightening torque
- Improper tightening order of bolts
Even with genuine wheels, even if the centering is slightly misaligned depending on how it is attached and detached, it can cause vibration.
If left unattended?
- Shake at high speeds is not stable and worsens
- Risk of loose wheel bolts
Cause (3): Individual differences in tires and the effect of changing the assembly direction
When does it happen?
- 4 Shake even when new
- Boom at a certain speed
- Shake strongly to either the left or right
Why do I have symptoms?
Even new products may resonate at a specific speed due to “individual differences” or “uneven stiffness”.
Also
- Direction of rotation (in and out)
- Habits caused by changing positions
- Differences in the way beads enter
There are surprisingly many patterns of shaking immediately after replacement.
In particular, VW has a stiff undercarriage and tends to have tire “habits”.
If left unattended?
- Reduced driving stability
- Discomfort in handling in rainy weather
Cause (4): A case where uneven wear tires come to the “front wheels”
When does it happen?
- I also rotated before and after at the same time
- Replacement only front/back only
- Originally, there were steps and pieces
Why do I have symptoms?
When the tires that were unevenly worn in rotation come to the front wheel side,
the shaking of the steering wheel suddenly surfaces.
- step → bulb vibration
- Reduced → Unstable straight
- Hardened tires → inconsistent grounding
If you swap the front and back when replacing it, this “habit” is likely to become noticeable.
If left unattended?
- Uneven wear is further
- Instability at high speeds worsens
Points that can be checked in DIY
- Tire pressure (left and right difference check)
- Is the balance weight off?
- Tightening the wheel nut
- Wrong rotation direction (IN/OUT, rotation direction tire)
- Check if the tires are stronger than before replacement
- Does the shaking change when the accelerator is turned on/off?
Is it okay to drive? (Urgency)
| Status | Risk level | Is it possible to drive? |
|---|---|---|
| Mild vibration | Medium | Be moderate at high speeds |
| Strong shaking at more than 100 km/h | High | High speed driving is not allowed (inspection recommended) |
| Possible nut loosening | Very high | Driving NG (immediate inspection) |
| I put uneven wear tires into the front wheel | High | Early repositioning or replacement |

When a driving problem occurs, it may be necessary to tow the truck depending on the situation.
In these cases, it may be covered by road assistance or riders of automobile insurance, so it is safe to lightly review the contents of your current contract.
If you may not have a proper understanding of the coverage, you can use a comparison service to check the coverage details and premiums of multiple companies at once. Since you can get a complete picture in a short time, many people use it for repairs and inspections.

Conclusion
High-speed vibration after changing tires is a very common cause of balance misalignment, lack of centering, and rotation.
A slight difference in replacement work can cause shaking, so it is important to readjust as soon as possible if you feel uncomfortable.
In particular, do not leave the bulbul around 100 km/h unattended.
Even if the symptoms are similar, the causes vary from vehicle to vehicle.
Even if there are similar abnormal noises and malfunctions, there are various causes such as turbo belts and sensors.
If you are unsure, it is safe to have it inspected at a maintenance shop without overdoing it.
Defect details by vehicle type
Although the “way of getting out” the defect is similar, “which model has many problems” is slightly different for each car model.
Trends by vehicle model and common breakdown cases among other owners are summarized on the following page.
Frequently Asked Questions (FAQs)
Q1. If vibration occurs at high speed immediately after changing tires, what is the first cause to suspect?
A. The most common is wheel balance misalignment. If it shakes around 80 to 100 km/h immediately after replacement, it is typical for balance errors and weight loss.
Q2. What is the difference between lack of centering and poor balance?
A. Poor balance is vibration caused by “weight bias”, and lack of centering is vibration caused by “the wheel does not rotate in a perfect circle”. Both are bulging at high speeds, but the difference is that lack of centering is likely to occur due to uneven external wheels and tightening.
Q3. Will there be vibration even though the tires are new?
A. Yes. There are cases where tires shake at a specific speed due to individual differences, uneven stiffness, and differences in assembly direction. In particular, VW tends to have a stiff suspension and is prone to “habits”.
Q4. Why did I get a burr when I rotated at the same time as changing tires?
A. When a tire that has been unevenly worn moves to the front wheel, it is easier to transmit vibration directly to the steering wheel. Tires with steps or chips are particularly shaky.
Q5. Is it okay to run even though it shakes at high speed? Should I check it right away?
A. If there is a clear vibration around 100 km/h, it is recommended to avoid driving at high speeds and inspect it. If there is a possibility of a loose nut, it is not allowed to drive. The earlier the diagnosis, the lower the cost.
