Choosing the right tires for your car is not just a matter of aesthetics, but fundamental to safety and comfort. For Skoda Superb, which combines the characteristics of a business sedan and a practical liftback, this choice becomes critical. Incorrectly selected wheels can ruin handling, increase fuel consumption and even damage the suspension.
Owners are often faced with a dilemma: install factory R16s to save money or upgrade to stylish R19s? In this article we will analyze in detail all the technical parameters that you need to know when buying new tires or replacing wheels. We will consider not only the diameter, but also the rim width, offset, center hole diameter and seasonal features.
Official tire and wheel sizes for Superb III
Manufacturer Skoda offers a wide range of factory wheel configurations for the third generation model. Depending on the configuration and engine type, the car can leave the assembly line with different dimensions. Basic versions are often equipped with steel or alloy wheels of R16 or R17, which is ideal for harsh operating conditions and poor roads.
More powerful modifications, such as versions with engines 2.0 TSI or hybrid Plug-in Hybrid, usually equipped with large disks R18 or R19. This is not just a tribute to fashion, but a necessity to ensure better traction at high speeds and dynamic acceleration. It is important to understand that increasing the diameter of the rim requires reducing the tire profile in order to maintain the overall outer diameter of the wheel.
Below is a table with the main factory sizes that are officially approved for Skoda Superb different years of manufacture:
| Diameter (R) | Disc width (J) | offset (ET) | Tire size (width/profile) | Note |
|---|---|---|---|---|
| 16 | 6.5J | ET 51-54 | 215/60 | Basic equipment |
| 17 | 7.0J | ET 43-50 | 215/55 | Most popular option |
| 18 | 7.5J | ET 40-45 | 235/45 | Sport style, comfort |
| 19 | 8.0J | ET 38-43 | 235/40 | Versions Sportline, VRS |
| 20 | 8.5J | ET 35-40 | 255/35 | Tuning, maximum width |
Pay attention to the parameter offset (ET). For this model, it varies over a fairly wide range, but going beyond the permissible values ββcan lead to wheel friction on the wheel arch liners or suspension elements when the vehicle is fully loaded. For the Superb III model, it is critical to maintain an offset within the range of ET 38-54 depending on the width of the rim.
β οΈ Warning: Installing wheels with a shorter offset than the factory offset (for example, ET 30 instead of ET 45) will result in the wheel protruding significantly beyond the body, which can be illegal and dangerous.
Parameters of mounting holes and centering rings
When choosing new disks, the mounting geometry cannot be ignored. For Skoda Superb, as for most cars of the group VAG, standardized squabbling is used. The number of fastening bolts is always 5 pieces, and the distance between the centers of the holes is 5x112. This is one of the most common standards in the European automotive industry.
The center hole (DIA) has the size 57.1 mm. This is a critical parameter. If you purchase discs from other brands (for example, BMW or Mercedes) which have a larger hole diameter, you will definitely need center rings. Without them, the wheel will be centered only on bolts, which will cause the steering wheel to beat at speed and accelerate the wear of the hub bearings.
- π§ Bolt pattern:
5x112(5 bolts, circumference diameter 112 mm) - π§ Center hole:
57.1 mm(Required to use rings when diverging) - π§ Bolt/nut thread:
M14x1.5(standard for the VW Group) - π§ Tightening torque:
120 Nm(Strictly follow this parameter)
Owners sometimes try to install discs from older models or from the same OctaviaThinking they'd be the right fit. Although the parameters may coincide, the geometry of brake calipers on the Superb It might be different. Never neglect to check the gap between the disc and the caliper.

- R18 (Optimal)
- R19 (Sport)
- R20+ (Tunning)
Effect of wheel size on driving performance
Changing the size of the wheels directly affects the behavior of the car on the road. Discs of smaller diameter, such as R16 or R17They usually have a higher profile of rubber. This works as an additional shock absorber, smoothing out the bumps of the asphalt and making the trip more comfortable. That is why for winter or bad roads, experts recommend this option.
On the other hand, disks R18 and R19 They look more aggressive and improve control. The smaller profile of the tire makes the reaction to steering more acute, and traction with the road during sharp maneuvers - more predictable. However, the price for this is the rigidity of the suspension, which will transfer every blow from the pits to the body and passengers.
Owners often wonder how the change in size will affect the speedometer and odometer. If you move on with 215/60 R16 on 235/45 R18The total diameter of the wheel will remain virtually unchanged, and the readings of the instruments will not be distorted. But if you set a disc that is too wide with a low profile, the speedometer may start lying, showing a speed below the real one.
β οΈ Attention: Increasing the width of the tire without checking the free space in the arches can lead to rubber grazing of the underwings when the steering wheel is turned or the trunk is fully loaded.
Before buying larger discs, be sure to measure the height of your carβs suspension if it has air suspension or undersuspension.
Specificity of summer and winter sets
For Skoda Superb It is recommended to have two sets of wheels: summer and winter. For winter, the ideal choice will be disks. R17 or R18 with studded or sticky rubber. In winter, not so much aesthetics is important, as reliability and passability. A thinner sidewall of a winter tire on the disc R19 It may be vulnerable to damage on iced curbs.
In the summer, you can afford a wider tire, for example. 235/40 R19. This will provide better handling in hot weather and when driving on the highway. A wide spot of contact with the road improves the braking distance on dry asphalt. However, on wet roads, too wide a tire may be prone to aquaplaning effects if the profile is too low.
- βοΈ Winter set: narrow profile (185-215 mm) on R16-R18 discs for better "gnawing" in snow
- βοΈ Summer set: broad-length (235-255 mm) on R18-R20 discs for track stability
- π§οΈ All-season option: compromise, but with less resource and worse performance in extreme conditions
Do not forget about the marking of speed and load indexes. For Superb diesel-powered 4x4 The load index should not be lower than 98 (800 kg per wheel). Ignoring this parameter can lead to a tire explosion when the car is fully loaded.
What are load and speed indices?
The load index (e.g. 98) shows the maximum weight that the tire can bear. The speed index (e.g. W) shows the maximum speed. For Superb, the indexes H, V, W, Y are often used.
Technical nuances of installation and balancing
The process of installing wheels requires strict compliance with technical regulations. After tyre installation on the discs must be carried out balancing. For large diameter (R19-R20) discs, this is especially important, as even a small imbalance at high speed turns into a strong vibration of the steering wheel or the entire machine.
When tightening the bolts, use a dynamometer key. Puffing moment for Skoda Superb amounts to 120 Nm. Untied bolts can fly out, and twisted bolts can tear the thread or deform the disk. It is also important to use the right bolts: conical bolts for stamped discs and special bolts for cast discs if the seat is different.
βοΈ Checklist before installation
It is also worth considering that when installing wheels with a low profile, the risk of damage to the disk on the curb increases many times. The cast discs are brittle, and the impact can cause cracks that are not visible visually but are dangerous when moving. Forged discs are more resistant to such blows, but are much more expensive.
Balancing and proper tightening of bolts is not just a formality, but a guarantee of the safety and durability of the suspension of your car.
Tuning and non-standard solutions
Many owners Skoda Superb strive for a unique appearance and install discs of non-standard sizes, for example, R20 or even R21. This requires careful preparation of the body. Often it is necessary to expand the arches, install the spacers or change the suspension so that the wheels do not touch the body when the suspension works.
The use of spacers (spacers) allows you to bring the wheel out, creating the effect of a βwide bodyβ. However, this increases the load on the hub bearings and suspension levers. If you decide to take this step, choose the exhibition from proven manufacturers with the right centering ring.
The insurance company may refuse to pay if it proves that the changed wheel parameters have affected safety.
- π Tuning: installation of pads for wheel removal requires strengthening of suspension
- π« Risks: changing parameters may result in a refusal to insurance or accident
- βοΈ Adaptation: (may require) replacement of levers or springs for new sizes
Which CDs are better?
cast or forged?: Cast discs are cheaper and easier to stamp, but fragile with strong impacts. Forged wheels are stronger and lighter than cast ones, but they cost 2-3 times more expensive. For the Superb, forging is a great choice for larger sizes.
FAQ: Frequently asked questions
Can I play the R20 on the Skoda Superb?
Yes, the Skoda Superb can be fitted with R20 discs, but this requires compatibility checks with a specific year of release and configuration. Usually, such dimensions are switched versions of Sportline or VRS. Make sure that the wheels will not touch the underwings when fully loaded.
Which offset (ET) is best for winter?
For winter, it is recommended to choose drives with a offset close to the factory (usually ET 43-50 for R17). Too large a flight can lead to friction on the suspension levers, and too small to friction on the wings and overload the hub bearing.
Will the Octavia A7 drives work for the Superb?
The mounting parameters (5x112, 57.1 mm) of the Octavia A7 and Superb III are the same. However, due to differences in suspension width and braking systems, some Octavia discs may not fit in width or offset. It is recommended to try on the discs before buying.
What load index is needed for a Superb with all-wheel drive?
For versions with 4x4 all-wheel drive and heavy diesel engines, it is recommended to use tires with a load index of at least 98 (800 kg) or 100 (800-850 kg), since the front axle is loaded more due to the weight of the engine and drive.
