Selection of rims for Skoda Superb 3 - This is not just a matter of aesthetics, but a complex engineering problem that affects the safety and handling of the car. This sedan, known for its spacious interior and comfortable suspension, requires a special approach to the chassis configuration. Incorrectly selected parameters can lead to rapid wear of the suspension, wheel alignment problems, and even loss of control over the car at high speed.
Owners often wonder what exact disc sizes are recommended by the manufacturer and whether it is possible to deviate from the standard values. Bolt pattern, offset, diameter of the central hole - all these parameters must be observed to the nearest millimeter. In this article, we will look at the technical nuances that will help you make an informed choice when purchasing both cast and stamped wheels.
Technical parameters and bolt pattern of Skoda Superb 3
The first thing you need to pay attention to when selecting wheels is the geometric characteristics. For Skoda Superb 3 (NB generation, since 2015) 5-bolt mounting is standard. This sets it apart from older models or compact classmates that often use 4 bolts. Incorrect calculation of the number of fasteners will make installation impossible or dangerous.
The key parameter is bolt pattern, which in this case is 5x112. This means that 5 mounting bolts are arranged around a circle with a diameter of 112 mm. Any deviation, even 0.5 mm, will result in the disc not seating tightly on the hub, which will cause wheel wobble and steering wheel vibration at speeds above 60 km/h. The size of the center hole is also critical.
The center mounting hole (DIA) should be 66.6 mm. If the disk has a hole of a larger diameter, it is necessary to use adapter centering rings. Ignoring this requirement will lead to the fact that the entire weight of the car will rest on the mounting bolts, and not on the central part, which can lead to thread breakage or disc deformation upon impact.
- βοΈ Bolt pattern (PCD): 5x112 mm - standard for most VAG models.
- π§ Center hole size (DIA): 66.6 mm - strictly adhere to.
- π οΈ Bolt/nut thread size: M14x1.5 - it is important to select the correct fasteners.
Wheel offset (ET) is another parameter that is often ignored when purchasing "nice" wheels. For Superb 3 Reach usually ranges from 43 to 55 mm. Increasing the offset can lead to friction between the disc and the suspension arms, and decreasing it can lead to excessive load on the wheel bearings.
Acceptable tire and wheel sizes
The manufacturer has provided several options for factory configuration to meet the needs of different drivers. Not only the appearance, but also the behavior of the car on the road depends on the size of the disc. The larger the rim diameter, the thinner the tire profile, which improves cornering control but makes the ride harsher and more vulnerable to potholes.
Most popular sizes for Skoda Superb 3 vary from 16 to 19 inches. Standard equipment is often equipped with R16 or R17 wheels with high profile tires, which ensures maximum comfort. Sports versions such as RS, come with 18 or 19-inch wheels and low-profile tires.
Below is a table with the most common wheel and tire size combinations recommended for various model versions:
| Disc diameter | Disc width (J) | offset (ET) | Tire size | Recommended version |
|---|---|---|---|---|
| 16" | 6.5J | 48 | 215/60 R16 | Basic equipment |
| 17" | 7.0J | 45 | 225/50 R17 | Active configurations |
| 18" | 7.5J | 43 | 235/45 R18 | Sport/Comfort |
| 19" | 8.0J | 43 | 255/40 R19 | RS or AMG version |
When choosing a size, be sure to consider the vehicle's ground clearance. Skoda Superb has sufficient ground clearance, but installing too wide wheels with a low profile can lead to damage to the tire on the arch when the car is fully loaded with passengers or luggage.
- βοΈ In winter, it is better to choose R16 or R17 wheels with a high profile to soften impacts.
- βοΈ In summer, R18 and R19 wheels are acceptable for better dynamics and appearance.
- βοΈ Keep an eye on the overall diameter of the wheel - it should not differ from the factory one by more than 2-3%.
If you install larger wheels, the actual speed will be higher than what the dashboard indicates. This can lead to unnoticed speeding and fines.
- R16 (Comfort)
- R17 (Golden mean)
- R18 (Sporty look)
- R19+ (Maximum aesthetics)
Cast, forged or stamped wheels: what to choose
There are three main types of wheels on the market, each with its own advantages and disadvantages. Stamped wheels (steel) are considered a classic choice for the winter. They are cheaper than cast ones and, more importantly, more ductile. If there is a strong impact on a hole, the steel wheel will bend, but it can be repaired at a tire shop, whereas a cast wheel may simply crack.
Cast aluminum alloy wheels are the most popular choice for Skoda Superb 3 in the warm season. They are lighter than steel, which reduces unsprung weight and improves acceleration and braking dynamics. They also offer a huge selection of designs and colors, allowing you to personalize your car.
Forged wheels represent the pinnacle of the technological process. They are made by hot stamping, which makes them as durable and lightweight as possible. However, their cost is significantly higher than their cast counterparts, and the choice of designs is limited. For everyday driving on city roads, forging is often excessive, but for track or aggressive driving it is ideal.
β οΈ Warning: Cheap alloy wheels from unknown brands often fail rigorous durability tests. When purchasing, always ask for a quality certificate and check for safety standards labeling.
When choosing disks, you should also pay attention to the coating material. Anodizing or painting in body color protects the metal from corrosion, but over time it can peel off when in contact with reagents. Powder painting is considered the most durable.
- π‘οΈ Stamping: Ideal for winter, repairable, cheap.
- β¨ Cast: Lightweight, beautiful, improves handling, resists strong impacts.
- π Forged: Maximum strength and lightness, high price.
Why can't you mix different types of disks?
If you install different discs on the axle (for example, cast in the front, stamped in the rear), this can lead to a difference in the weight of the wheels and, as a result, imbalance of the car when braking and cornering. The suspension may not work correctly, increasing the risk of skidding.-->
Seasonal operation and winter package
For residents of regions with harsh climates, the issue of disc seasonality is especially acute. Changing tires on rims is not only changing tires, but also changing the rims themselves. Using a winter set of alloy wheels allows you to save time and money on tire fitting, as well as preserve the appearance of summer wheels from reagents and salt.
When choosing winter wheels for Skoda Superb 3 It is recommended to give preference to smaller diameter wheels with a high tire profile. This creates an βair cushionβ that softens impacts on road irregularities hidden under the snow. Low-profile tires on ice or slush can cause the disc to puncture on a hidden rock.
It's important to consider that winter tires usually have a softer compound and may slightly increase braking distances. Proper selection of disc size helps compensate for this effect by increasing the contact patch and better shock absorption.
β οΈ Attention
β οΈ Attention
Make sure that winter wheels do not touch the fender liners or arches when the suspension is fully compressed. On vehicles with adaptive ground clearance this can be a critical factor.
Many owners Superb use universal R17 wheels, which are suitable for both winter and summer. This is a compromise option that allows you to avoid buying two sets, but requires careful selection of tires for each season.
βοΈ Preparing for the change of season
Installation safety and fastening
Correct installation of disks on Skoda Superb 3 - security deposit. Incorrect tightening of bolts can lead to their unwinding in the way or, conversely, to the failure of the thread. The puff time for this model is usually 120 Nm. The use of a dynamometer key is mandatory for self-installation.
The mounting bolts must match the type of disk. Cast discs often require spherical head or cone bolts, while stamped ones may use flat head bolts. The use of the wrong type of fastener will lead to uneven adjoining of the disc to the hub.
It is also worth paying attention to the state of the hub hole. If the disc is not tight due to corrosion or dirt, the wheel beat is guaranteed. Before installation, it is necessary to carefully clean the seat on the hub and the disk itself.
- π§ Puff time: 120 Nm β use the dynamometer key.
- π© Type of bolts: Cone 60Β° or sphere 90Β° - strictly according to the type of disk.
- π§Ό Clean: Clean the hub of rust and dirt before installation.
After installing a new set of disks, it is highly recommended to check for collapse-convergence. Even a slight deviation in the geometry of the suspension can lead to uneven wear of the tires and deterioration of the course stability.
The ideal winter kit for the Skoda Superb 3 is steel or inexpensive alloy wheels with a diameter of R16-R17 with a high tire profile, which provides maximum suspension protection and comfort on bad roads.
Additional accessories and tuning
Besides the discs themselves, there are a number of accessories that can simplify operation and improve the appearance of the car. Climbers on stamped discs are a great way to protect the discs from corrosion and give the car a more complete look. However, they must be securely fixed so as not to fly at speed.
For cast discs, decorative bolt plugs are a popular solution. They not only look aesthetically pleasing, but also protect the carving from dirt and moisture. It is also worth considering installing tire pressure sensors (TPMS) if they have not been installed from the factory. This will allow you to control the pressure in each wheel in real time.
If you want to install discs with a larger diameter or a wider offset, you may need to install supply rings. They allow you to move the wheel outwards, improving the track, but increase the load on the hub bearings. Use them with caution and only high-quality products.
β οΈ Attention: Installing the pads increases the wheel's flight, which can cause the wing arch to touch when turning the steering wheel or fully loading the car. Be sure to check the gaps before operation.
Owners Superb 3 Often choose discs with the technology of "split design", where the center part and spokes are made of different materials or colors. This creates a depth effect and makes the wheels more expressive, especially when combined with a dark body color.
FAQ: Frequently asked questions
Can I install ET40 drives instead of the ET45?
Technically, you can install such a disc, but it will move the wheel outwards by 5 mm. This will increase the load on the hub bearing and may cause the arch to touch when the suspension is completely compressed. It is recommended not to deviate from factory values by more than 3-4 mm in either direction.
Do I need to change bolts when changing from stamped wheels to cast ones?
Often, yes. In stamped discs, bolts with a flat head are usually used, and in cast ones - with a cone or spherical one. The wrong type of bolt will not allow you to press the disc tightly against the hub, which is dangerous. Always check the type of bolt head and buy a new kit if necessary.
What is the maximum size of the tyres you can put on the Skoda Superb 3?
The maximum factory size for most versions is 255/40 R19. Installation of larger tires (for example, R20) is possible, but will require mandatory fitting of arches, installing pads and can adversely affect the operation of the suspension and electronics of the car.
Why does the disk hang on the hub even with tight bolts?
The problem is probably centering. If the diameter of the central disc hole (DIA) is larger than the hub (66.6 mm) and you do not use transition rings, then the disc is centered only on bolts. That's unacceptable. Install high-quality aluminum rings-centering.
