Selection of rims for Škoda Octavia A7 (2013–2020) is a task that requires attention to technical details. One of the key parameters is drilling (PCD), which determines the compatibility of the disc with the vehicle's hub. An incorrect selection can lead to vibrations, uneven tire wear, or even damage to the suspension. In this article we will look at the standard drill sizes for Octavia A7, permissible deviations, nuances of compatibility with other models Volkswagen Group and give practical recommendations for choosing.
Feature Octavia A7 — platform unification MQB with other cars of the concern, which expands the options for selecting wheels. However, even within the same platform there may be differences depending on the year of manufacture, configuration or type of drive (front/all-wheel drive). We analyzed official data Škoda, owner reviews and technical documentation to provide up-to-date information.
Standard drilling parameters for Škoda Octavia A7
Basic parameters of wheel rims for Octavia A7 (including 2017 facelift) are given below. This data is relevant for most trim levels, but always check it for your specific modification.
| Parameter | Meaning | Notes |
|---|---|---|
| Drilling (PCD) | 5×112 |
5 holes, circle diameter 112 mm |
| Center Hole Diameter (DIA) | 57.1 mm |
May vary for after market discs |
| offset (ET) | 38–50 mm |
Depends on rim width and drive type |
| Mounting thread | M14×1.5 |
Standard for all modifications |
| Stud size | 27 mm |
Thread length |
Important: parameters offset (ET) and rim width may differ for versions with all-wheel drive (4×4) and sports packages (RS). For example, for Octavia RS Offset discs are often used ET45 and width 7.5J–8.5J, while for basic versions they are relevant ET38–42 and 6.5J–7J.
If you plan to install discs with non-standard DIA (for example, 66.6 mm for universal disks), you will need centering rings. Their absence can lead to wheel runout and premature wear of the wheel bearing.

Compatibility with other VAG models: what can be installed on the Octavia A7
Thanks to the platform MQB, Škoda Octavia A7 Compatible with drives from a range of models Volkswagen Group. This expands the choice and allows you to save on buying used disks. However, there are nuances:
- 🔄 Full compatibility (without modifications): Volkswagen Golf VII, Audi A3 8V, SEAT Leon 5F, Škoda Superb 3T (pre-facelift). These models have identical drilling
5×112andDIA 57.1 mm. - ⚠️ Partial compatibility (verification required): Volkswagen Passat B8 (some versions have
DIA 65 mm), Audi TT 8S (offset may vary). - ❌ Incompatible without adaptation: Volkswagen Tiguan AD (drilling
5×112, but is often usedET50+which is not suitable for Octavia), Škoda Kodiaq (due to the greater mass, wheels with a reinforced design are required).
When purchasing disks from other models, be sure to check:
- Sverlovka (
PCD 5×112- definitely!). - Central hole diameter (
DIA). If it's bigger57.1 mm, centering rings will be required. - Departure (
ET). A deviation of more than ±5 mm from the standard value can lead to wheel friction on the arch or incorrect operation of the suspension.
⚠️ Attention: Discs from Volkswagen Polo or Škoda Fabia (platformPQ25) are not suitable for Octavia A7 due to another drilling (4×100or5×100). Their installation is impossible without adapters, which is strictly not recommended for security reasons.
Permissible deviations: when you can deviate from standards
In some cases, minor deviations from standard parameters are possible, but they must be justified and calculated. Let's consider the valid options:
- 📏 offset (ET): Please allow ±5 mm deviation from the recommended value. For example, if the normal departure
ET42, you can use discs withET37–47. Larger deviations will lead to: - Displacement of the steering axis (deterioration of controllability).
- Increased load on wheel bearings.
- 🕳️ Center Hole (DIA): Maybe more than regular, but not less! For example, a disk with
DIA 66.6 mmsuitable if you use the centering ring up to57.1 mm. The opposite situation (smaller diameter) will make installation impossible. - 🔧 Disc width: An increase of 0.5–1 inch from the standard one is allowed (for example, with
7Jup to8J), but it requires adjusting the offset and checking the gaps in the arches. Reducing the width is undesirable - it worsens the stability of the car.
Critical note: Wheels with 5x112 drilling, but intended for vehicles weighing more than 2 tons (for example, some versions Volkswagen Transporter), not suitable for Octavia A7 despite the PCD matching. Their design is not designed for the dynamic loads of a passenger car.
What happens if you ignore disk failure?
Installing discs with incorrect offset leads to a displacement of the wheel plane relative to the hub. This calls:
- Accelerated wear of bearings (2–3 times faster).
- Uneven tire wear (especially the inner edge).
- Deterioration of directional stability at high speeds (the car may “yaw”).
- Risk of damage to suspension elements when falling into a hole.
If you plan to install disks with non-standard parameters, we recommend:
- Check the suspension geometry on the stand after installation.
- Use spacers (if you need to increase the reach) or wheels with negative offset (for tuning), but only after consultation with a specialist.
- Please note that a change in offset by more than ±10 mm requires re-registration with the State Traffic Safety Inspectorate (in Russia and the CIS countries).
How to measure the drill bit and center hole yourself
If you are buying used wheels or are in doubt about markings, drilling and DIA you can measure it yourself. You will need:
- 📐 High precision caliper or ruler.
- 🔍 Magnifier (for reading markings on the back of the disc).
- 📝 Paper and pencil for notes.
PCD (drilling) measurement:
- Measure the distance between the centers of two adjacent holes (for example,
L). - For 5 hole discs use the formula:
PCD = L / 0.5878(for Octavia A7 the result should be close to112 mm). - Check all pairs of holes - discrepancies of more than 0.5 mm indicate disc deformation.
DIA measurement:
Simply measure the diameter of the center hole with a caliper. For Octavia A7 standard value - 57.1 mm, but discs with DIA up to 66.6 mm (with centering rings).
⚠️ Attention: If there is no offset marking on the disc (ET), its independent measurement requires a special tool (for example, reach measuring devices). Without it, it is impossible to determine the parameter with sufficient accuracy.
Drilling corresponds to 5×112
The diameter of the central hole is not less than 57.1 mm
Overhang (ET) within ±5 mm of standard
No cracks or deformations

Tuning and non-standard solutions: what you need to know
Many owners Octavia A7 strive to improve the appearance of the car with the help of non-standard wheels. Let's look at popular options and their consequences:
- 🔥 Discs with negative offset (for example,
ET20): give the car an aggressive look, but: - Increases the load on bearings and suspension arms.
- The arches may require modification (rolling out).
- In Russia, they require changes to the PTS.
- ⚡ Forged wheels: lighter and stronger than cast ones, but:
- They cost 2–3 times more.
- Sensitive to the quality of the road surface (risk of cracks due to strong impacts).
- 🎨 Disks with hubs (replica): copies of original discs Audi or VW:
- Often have inaccurate geometry (check the balancing!).
- May not correspond to stated parameters
PCDorET.
When choosing tuning wheels, pay attention to:
- Load Index: must be no lower than standard (for Octavia A7 - usually
600–650 kgon the wheel). - Certification: discs must be marked
ECEorSAE. - Manufacturer's warranty: reliable brands (BBS, OZ Racing, Ronal) provide a guarantee on geometry.
Before purchasing tuning discs, check them for compatibility with your version Octavia A7 through online services, for example, wheel-size.com. Enter the car model and disk parameters - the system will show possible problems.
Common mistakes when choosing disks and how to avoid them
Even experienced car owners sometimes make mistakes when selecting wheels. Let's look at the most common ones:
- 🔍 Ignoring markings: The back of the disc contains all the necessary information (for example,
7.5J×17 ET45 PCD5×112 DIA57.1). Neglecting this data leads to the purchase of incompatible disks. - 💰 The pursuit of cheapness: Discs without certification or with a questionable history (for example, after strong impacts) may be destroyed while driving.
- 🔧 Ignoring drive type: wheels for front wheel drive Octavia may not be suitable for version 4×4 due to different offsets and loads on the hubs.
- 🌡️ Neglect of balancing: Even new drives require balancing during installation. An unbalanced wheel causes vibrations at speeds above 90 km/h.
To avoid problems:
- Buy discs from trusted stores (for example, Kolesa-Darom, BlackTyres, official dealers Škoda).
- Request a certificate of conformity and a warranty card.
- Before payment, check the disk parameters with the data from the instruction manual Octavia A7.
⚠️ Attention: Discs with a damaged paint surface (chips, corrosion) may have hidden microcracks. Such defects are not always visible to the naked eye, but lead to the destruction of the disk under load.
When purchasing used wheels, be sure to check them for runout. To do this, install the disk on a balancing machine or spin it on weight - any deviations from the plane of rotation are unacceptable.
FAQ: Answers to frequently asked questions about drilling Octavia A7
Is it possible to install 5x100 rims on Octavia A7?
No, this is not possible without adapters. Sverlovka 5×100 incompatible with 5×112 for two reasons:
- Different number of holes (although both options have 5 studs, their location is different).
- Different circle diameters (
100 mmvs112 mm).
Using adapters for such conversion is extremely dangerous - it disrupts the geometry of the mount and increases the risk of the wheel coming off.
Which wheels from other brands are suitable for the Octavia A7 without modifications?
Drives from the following models are fully compatible (subject to matching ET and DIA):
- Volkswagen Golf VII (2012–2019).
- Audi A3 8V (2012–2020).
- SEAT Leon 5F (2012–2020).
- Škoda Superb 3T (pre-facelift, 2015–2019).
Before purchasing, check the parameters of a specific drive - even within the same model there may be variations.
What should I do if I bought wheels with DIA 66.6 mm?
This is a common situation - many universal drives have DIA 66.6 mm. Solution:
- Buy centering rings with outer diameter
66.6 mmand internal57.1 mm. - Make sure the rings are made of durable plastic or aluminum (cheap rubber alternatives wear out quickly).
- Check the fit of the disc on the hub - play is unacceptable!
The cost of rings is from 200 to 600 rubles for a set of 4 pieces.
How does changing the reach affect handling?
Deviation of the offset from the standard value affects:
| Reach change | Consequences |
|---|---|
Decrease (ET gets smaller) |
The wheel moves outward, the track increases. This improves cornering stability, but accelerates bearing wear and can lead to arch friction. |
Magnification (ET getting bigger) |
The wheel is “recessed” inward, the track is reduced. This reduces the load on the suspension, but impairs directional stability and can cause friction with the brake system components. |
The optimal deviation is no more than ±5 mm. To fine-tune the geometry after changing the offset, a visit to the wheel alignment stand is required.
Is it possible to install disks from Octavia A5 on A7?
No, that's impossible. Škoda Octavia A5 (2004–2013) has drilling 5×112, but:
- Uses the platform
PQ35(unlikeMQBat A7). - Has a different diameter of the central hole (
DIA 57.1 mmmatches, but the offset and width of the rims are different). - Discs from A5 often have a lower load index, which is dangerous for A7 (especially for versions with engines
1.8 TSIor2.0 TDI).
