Buying discs for a car that was released more than a decade ago often becomes a real puzzle for the owner. This is especially true for mass models such as Skoda Superb The second generation, which was produced from 2008 to 2015. Owners Skoda Superb 2012 Years of release face the need to replace the rubber or upgrade suspension, where the key parameter is the squabbling.
Incorrect selection of wheels can lead to serious problems: from vibration at high speeds to loss of the wheel on the go. Unlike modern models, where standards are unified, old bodies have their own specific mounting features. In this article, we will discuss in detail all the technical characteristics that you need to know before going to the auto parts store.
Basic PCD parameters and wheel mounting
The most critical parameter that determines the compatibility of the drive with your car is the bolt pattern or PCD (Pitch Circle Diameter). For Skoda Superb 2012 This parameter is strictly standardized and does not depend on the configuration or type of engine. Knowing the exact numbers will eliminate the risk of buying incompatible parts.
In the vast majority of cases, this model is used 5x112. This means that 5 bolt holes are located on a circle with a diameter of 112 millimeters. Errors are unacceptable here, since a disk with a PCD 5x100 or 5x114.3 will not physically wear on the hub without the use of transitional slots, which is extremely undesirable.
- π© Standard PCD value: 5x112 mm
- π§ Number of holes: 5 piece
- βοΈ Center hole diameter: 57.1 mm
It is important to consider that some early versions or specific sporting modifications could theoretically have been different, but for the 2012 mass-produced 5x112 rule is absolute. If you see a 5x100-marked disc, itβs definitely not your option, even if the seller claims otherwise.
β οΈ Note: The use of transition rings to compensate for the difference in PCD is strictly prohibited, as this changes the geometry of the load on the hub bearing and can lead to its instantaneous destruction.
Diameter of the central opening and the centering
In addition to the squabbling, a critical parameter is the diameter of the central hole, often referred to as the "Central Hole" DIA or CO. For Skoda Superb 2012 This indicator is exactly 57.1 mm. It is this hole that ensures the exact landing of the disc on the hub of the car until the bolts are tightened.
If the diameter of the disc hole is greater than 57.1 mm, the disc will hang on the bolts, which will cause the wheel to beat when moving. If the hole is smaller, the disc simply will not fit on the hub. In some cases, a large DC disk is allowed, but only if plastic or metal center rings are installed, which compensate for the difference.
- π Standard CO diameter: 57.1 mm
- π Permissible error: 0 mm (no rings)
- π οΈ The solution for large holes: Centering rings
Many owners ignore this parameter, believing that the main thing is the coincidence of bolts. However, it is the hub centering that removes the main load from the fasteners. When tightening, bolts should only fix the disk, and not hold its weight and center it. Central hole You should sit in the hub tightly, without backlashes.
When buying used discs, always check the diameter of the hole with a rod. Corrosion or impacts can deform the edge, which is visually imperceptible but critical for centering. Also pay attention to the quality of the metal in the hole area.
β οΈ Attention: A loose landing on the central hole causes the steering wheel to beat at speeds above 60 km / h, which is a direct sign of improper disk selection or hub wear.
Type sizes of bolts and nuts
For fixing the wheels on Skoda Superb 2012 Metric threaded bolts are used. The standard size of the thread is M14x1.5. This means that the diameter of the thread is 14 mm, and the thread pitch is 1.5 mm. The wrong step of the thread will lead to the impossibility of tightening or failure of the thread in the hub.
The length of the bolt also matters. It depends on the thickness of the disk and the presence of slats. The standard length of the bolt for regular disks usually varies between 27-30 mm in thread. When installing cast discs with great depth (flight) may require longer bolts.
- π© Bolt thread: M14x1.5
- π Turnkey size: 17 mm (standard) or 19 mm (for some brackets)
- π Saddle cone: 60 degrees (spherical)
Pay attention to the type of saddle bolt. For most of the Volkswagen Group models, including Skoda SuperbIt uses a cone type with an angle of 60 degrees. The use of ball saddle bolts (often found on older Japanese cars) is unacceptable and dangerous.
If you plan to install slots between the disc and the hub, you need to use elongated bolts. In this case, standard bolts may simply not reach the thread in the hub, which will lead to an emergency. The length should be calculated individually for the thickness of the stretcher.
Disk sizes and departures (ET)
Parameter ET (departure) determines how deep the disk is sunk into the arch or, conversely, protrudes outward. For Skoda Superb 2012 Factory ET values are usually in the range of 40 to 50 mm. Deviation from this value changes the width of the track of the car and the load on the suspension.
Installing discs with a smaller offset (e.g. ET 35) will cause the wheel to protrude outside the arch. This can cause friction on the wing when cornering or loading the trunk. The increased offset (ET 55 and above) simplifies the wheel inwards, which can lead to friction on the caliper or suspension elements.
The disk width (J) for this model also has its own standards. It's usually 7.0 or 7.5 inches. For winter tires, narrower wheels (6.5J) are often chosen to compress the tire and improve its contact with the road. For summer tyres and sporty style, wider options up to 8.0J are suitable.
- π Standard offset (ET): 40-48 mm
- π Disc width (J): 7.0J (basic standard)
- π§ Maximum tolerance: Β±5 mm
When choosing non-standard disks, the electronics of the car are designed for a certain rolling radius and track width. Severe deviations can lead to false alarms of stabilization systems.
- Cast (light alloy)
- Forged
- Steel (stamped)
- Carboniferous (hypothetically)
Seasonal features and tire selection
The choice of discs depends on the season. Steel stamped discs are often recommended for winter. They are cheaper, easier to bend when hitting a hole and easier to recover. For Skoda Superb 2012 The R16 or R17 dimension is optimal for winter, as it allows for a higher tire profile.
In the summer, owners often switch to alloy wheels in size R17 or R18. A larger disc diameter improves handling and appearance, but requires low-profile rubber, which is less resistant to impacts and uneven road surfaces. The compromise is the size R17, which is suitable for both seasons.
- βοΈ Winter option: R16/R17 with high profile
- βοΈ Summer option: R17/R18 low profile
- π Sports option: R19 (requires caution on bad roads)
The tire size must correspond to the factory recommended values for a specific engine and suspension type. On Skoda Superb 2012 tires of sizes 215/60 R16, 235/45 R17 or 235/40 R18 are often found. It is not recommended to install tires that are not specified in the vehicle documentation without consulting with specialists.
When changing seasonal tires, be sure to check the condition of the bolts and discs. Winter salt and reagents can cause thread corrosion, causing the bolts to become sour. Before installing the wheels for the winter, it is recommended to treat the threads with graphite lubricant or copper paste.
β οΈ Attention: Installing rims with the wrong offset or width may result in the wheel hitting the suspension elements when the vehicle is fully loaded, which can result in loss of control.
βοΈ Check before purchasing discs
Common mistakes during selection and installation
One of the most common mistakes is trying to install disks from other VAG models without checking the parameters. For example, disks from Skoda Octavia or Volkswagen Passat may have similar dimensions, but differ in reach or type of bolt fastening. Always check the compatibility chart.
Another mistake is using bolts with the wrong taper. Some owners try to match bolts from other car brands, which leads to uneven tightening and the wheel loosening while driving. Bolts must be strictly M14x1.5 with a 60 degree cone.
It is also worth paying attention to the condition of the hub. If you have removed the old wheels and noticed rust or damage on the seat, you will need to clean it before installing new wheels. Any irregularities on the hub will cause the wheel to wobble.
- β Error: Using bolts from other brands
- β Error: Ignoring centering rings
- β Error: Tightening bolts without a torque wrench
The wheel bolts must be tightened with a torque wrench to the torque specified in the instructions. For Skoda Superb 2012 this is usually 120 Nm. Undertightening leads to self-unscrewing, and overtightening leads to stretching of the bolts and their subsequent breakage.
What to do if the disc does not fit on the hub?
Check the diameter of the center hole. It is possible that the disc has a CO of 57.1, but the edge is deformed or corroded. Clean the landing site and try again. If the disc diameter is less than 57.1, the disc will need to be bored or replaced.

Conclusion and final recommendations
Selecting disks for Skoda Superb 2012 requires attention to detail. The main parameters are bolt pattern 5x112, central hole 57.1 mm and correct bolt threads M14x1.5. Compliance with these conditions guarantees safety and comfort while driving.
Do not skimp on the quality of fasteners and centering rings. Cheap bolts can burst under high loads, and the lack of a center hole will cause vibration that will destroy the suspension components. Always check that the wheel meets your vehicle's specifications before installation.
If you are not sure about the parameters, it is better to contact an official dealer or a specialized service. Properly selected wheels will last a long time and provide reliable traction in all conditions.
Before installing new discs, be sure to clean the hub of rust and dirt to ensure perfect alignment and eliminate wheel runout.
What bolt size is needed for Skoda Superb 2012?
For standard wheels, threaded bolts are used M14x1.5 and length, depending on the type of disk. The standard thread length is about 27-30mm. When installing spacers, the length of the bolt must be increased.
Is it possible to install wheels with PCD 5x100 on Skoda Superb 2012?
No, wheels with a 5x100 bolt pattern will not fit. The only option is to use spacers that move the mount to 5x112, but this is not recommended due to the reduced safety and load on the hub.
What is the tightening torque for the wheel bolts?
The recommended tightening torque for M14 bolts is 120 Nm. Tightening must be done crosswise with a torque wrench.
Are centering rings required for alloy wheels?
If the diameter of the center hole of the disc exactly matches the hub (57.1 mm), rings are not needed. If the hole is larger, rings are required for proper alignment.
What disc offset is best to choose for winter?
For winter it is better to choose an offset in the range 40-45 mm. This will provide reliable protection from snow and mud, and will also reduce the load on the hub bearings compared to extremely wide discs.
Exact adherence to the parameters PCD 5x112 and CO 57.1 mm is a guarantee of the safety and durability of the chassis of your Skoda Superb.
