Owners ล KODA Octavia RS know: this car combines sporty character with the practicality of a family sedan. But even the most advanced suspension and powerful engine will not reveal their potential without properly selected wheels. Not only the appearance of the car depends on them, but also handling, tire wear, and in some cases, even fuel consumption.
In this article we will look at all key parameters of wheels for Octavia RS - from factory sizes to the nuances of choosing cast, forged and stamped options. You will learn which brands are trustworthy, how to avoid mistakes when purchasing, and what to do if you want to purchase wheels larger than standard ones. We will also reveal myths about the influence of discs on dynamics and comfort, which often mislead car owners.
Original ล KODA Octavia RS wheel sizes: what the factory offers
The manufacturer installs on Octavia RS wheels with strictly defined parameters that guarantee safety and optimal driving performance. For different generations of the model, these dimensions may differ slightly, but the general logic remains the same.
For Third generation Octavia RS (2013โ2020) and the restyled version (2017โ2020) the standard parameters are as follows:
- ๐ง Diameter: 17โ19 inches (depending on configuration)
- ๐ Width: 7.0Jโ8.0J
- โ๏ธ offset (ET): 45โ50 mm
- โญ PCD (bolt pattern): 5ร112
- ๐ณ๏ธ Center Hole (DIA): 57.1 mm
Fourth generation (Octavia RS 2020+) received minor changes:
- ๐ง 18-19 inch wheels have become standard even in basic versions
- โ ๏ธ Departure
ET48is now more common thanET50 - ๐ Allowed width up to
8.5Jfor 19" variants
โ ๏ธ Attention: Installing discs with offsetET < 40or> 52can lead to premature wear of wheel bearings and disruption of suspension geometry. This is not just a recommendation - such cases are recorded in service centers ล KODA.
| Generation | Years of manufacture | Standard Diameter (inches) | Width(J) | Reach (ET, mm) |
|---|---|---|---|---|
| Octavia RS III (pre-restyle) | 2013โ2016 | 17โ18 | 7.0โ7.5 | 45โ50 |
| Octavia RS III (restyle) | 2017โ2020 | 18โ19 | 7.5โ8.0 | 48โ50 |
| Octavia RS IV | 2020โpresent time | 18โ19 | 7.5โ8.5 | 45โ48 |
For example, disks with ET38 may touch the brake caliper when the vehicle is fully loaded or on uneven roads.

Cast, forged or stamped: which is better for the Octavia RS
Choosing the type of disk is always a compromise between price, weight, strength and appearance. Let's look at the pros and cons of each option in relation to Octavia RS.
Alloy wheels - the most popular choice among owners RS versions. They are 20โ30% lighter than stamped ones, which improves dynamics and reduces the load on the suspension. However, there are nuances:
- โ Lightness (weight of a 17-inch disk is ~7โ9 kg versus 10โ12 kg for a stamped one)
- โ Wide range of designs (from classic to aggressive sports models)
- โ Fragility under strong impacts (cracks when hitting a hole at speed)
- โ High price for quality brands (from 15,000 rubles per set)
Forged wheels โ a premium option for those who value reliability and are willing to pay for it:
- โ Durability (withstands impacts that would destroy a cast disc)
- โ Minimum weight (10โ15% lighter than cast analogues)
- โ Long service life (do not corrode, do not deform)
- โ Price (from 30,000 rubles per set)
- โ Limited selection of designs
Stamped discs - a budget solution that is not suitable for everyone:
- โ Cheap (from 3,000 rubles per disc)
- โ Maintainability (can be rolled after an impact)
- โ Heavy weight (impairs acceleration and braking)
- โ Boring design (usually only basic models)
- โ Corrosion (requires regular painting)
โ ๏ธ Attention: If you plan to participate in track days or ride aggressively on serpentine mountain roads, forged wheels are the only safe choice. Alloy wheels can burst under extreme loads, causing loss of control.
When purchasing alloy wheels, check for a certificate TรV or ISO 9001 - this is a guarantee that the disc has passed crash tests and will not shatter into pieces in an accident.
How to choose non-original wheels: what to look for
If you decide to move away from factory settings, there are a few critical things to consider. An error in choice can result not only in a fine for not complying with traffic regulations, but also in suspension failure or even an accident.
1. Bolt pattern (PCD)โ to be5ร112. No adapters or โalmost fitโ options! Even the slightest discrepancy will lead to steering wheel wobble and uneven tire wear.
2. offset (ET) โ optimal range for Octavia RS:
- ๐น
ET45โET50- standard values - ๐น
ET40โET44โ acceptable, but requires checking for contact with calipers - ๐น
ET < 40or> 52โ strictly prohibited (risk of hub breakage)
3. Width and diameter โ there is room for maneuver here, but with reservations:
- ๐ 17" wheels: width
7.0Jโ7.5J - ๐ 18-inch:
7.5Jโ8.0J - ๐ 19-inch:
8.0Jโ8.5J(only for low profile tires!)
Exceeding the width by more than +1.0J from the standard value will require rolling out the arches or installing gaskets, which is not always legal.
Ensure PCD matches (5x112)|Check offset (ET45โET50 for most cases)|Check center hole diameter (57.1mm)|Consult tire shop for compatibility with brake system-->
Best wheel brands for Octavia RS: 2026 ranking
Not all drives are created equalโeven if they fit the specs. The quality of the metal, production technology and control at the casting stage determine how long the disc will last and how it will behave in an emergency.
Here TOP 5 brandswho have earned the trust of their owners Octavia RS:
- BBS - a legendary German brand, supplier for factory RS kits. Discs BBS CH-R and BBS CI-R Ideal for sporty riding.
- OZ Racing โ Italian quality with aggressive design. Models OZ Ultraleggera and OZ Superturismo popular among tuners Octavia.
- Ronal โ Swiss reliability. Ruler Ronal R51 often installed on ล KODA from the factory.
- AEZ - a German manufacturer with a good price/quality balance. Models AEZ Le Mans and AEZ Sienna suitable for everyday use.
- Replica - budget analogues of the original discs. Quality varies, but models Replica RS6 often praised for faithfully replicating factory designs.
If your budget is limited, pay attention to wheels from Czech manufacturers, such as Alcar or Dezent - they specialize in group cars VAG and offer good value for money.
Why shouldn't you buy discs from no-name brands?
Cheap wheels are often made from recycled aluminum with alloys, which makes them brittle. In 2023, several cases were recorded in Russia when alloy wheels of unknown brands cracked at speeds above 120 km/h, leading to accidents. Even if the disc looks perfect on the outside, its internal structure may contain microcracks that are invisible to the eye.
Disks larger than standard: pros and cons of the upgrade
Many owners Octavia RS they want to install larger wheels - for example, 19 or even 20 inches instead of the standard 17-18. Let's look at what this gives and what pitfalls such tuning hides.
Pros of larger disks:
- ๐ Appearance: the car looks sportier and more modern
- ๐ Brake system: better cooling of brake mechanisms (relevant for 19-inch wheels)
- ๐ Handling: clearer response to steering wheel turns (due to the rigidity of the sidewall of low-profile rubber)
Cons:
- ๐ฐ Price: 19-inch wheels + low-profile tires will cost 1.5โ2 times more than a standard set
- ๐ฃ๏ธ Comfort: ride stiffness increases by 20โ30% (every bump and hole is felt more strongly)
- ๐ง Repair: low-profile tires are more likely to puncture and rims are more easily damaged on bad roads
- โ๏ธ Legal risks: if the diameter exceeds the factory tolerances by more than 1 inch, there may be problems with passing maintenance
The optimal compromise for Octavia RS โ 18-inch wheels with tires 225/40 R18 or 235/40 R18. This size strikes a balance between appearance and practicality without sacrificing comfort.
Increasing the diameter of the rims by 1 inch requires reducing the tire profile by 10โ15 mm in order to maintain the outer diameter of the wheel. For example, going from 17โณ (225/45) to 18โณ will require 225/40 tires.
How to avoid mistakes when purchasing: a checklist from an expert
Even experienced car owners sometimes make mistakes when choosing wheels. Here 5 most common mistakes and how to avoid them:
1. Buying wheels without checking on the car
Never take discs by eye, even if the parameters match. Always try the disc on the hub or at least check the 3D model in a program like Wheel-Size.com. For example, disks ET40 may touch the caliper Octavia RS with brakes 340 mm.
2. Ignoring the weight of the disc
A difference of 1โ2 kg per wheel may seem insignificant, but in practice it is:
- ๐ Increase in fuel consumption by 0.3โ0.5 l/100 km
- ๐ Extending the braking distance by 1โ2 meters
- ๐ Slower acceleration (especially noticeable on Octavia RS 2.0 TSI)
3. Savings on bolts and nuts
Standard bolts from ล KODA not always suitable for non-original discs. Use reinforced bolts with tapered fit (for example, Bimecc or Febi), if the disk has recessed holes for fasteners.
4. Neglecting balancing
New wheels necessarily need to balance with tires! Even minimal imbalance at speeds of 120+ km/h leads to steering wheel wobble and accelerated bearing wear.
5. Buying used disks without checking
When inspecting, pay attention to:
- ๐ Cracks around bolt holes
- ๐ Rim deformation (checked by simply rolling the disc on a flat surface)
- ๐ Traces of corrosion on the inside (especially for stamped discs)
Before purchasing wheels, take a photo of your current wheels from two angles (front and side) and show it to the seller. This will help avoid mistakes with offset and width.
