Selecting disks for ŠKODA Octavia A7 (2013–2020) is a task that requires attention to technical nuances. Incorrectly selected parameters can lead to premature wear of the suspension, deterioration in handling, or even refusal to pass inspection. In this article we will analyze original sizes, permissible deviations in reach (ET) and bolt pattern (PCD), and also give recommendations on brands and materials.
Model range Octavia A7 includes versions with different engines and suspensions, which affects the choice of wheels. For example, for cars with all-wheel drive (4x4) and sports packages (RS) requires special parameters. We will also look at how to avoid common mistakes when purchasing and installing, and give tips on caring for wheels on Russian roads.
Original wheel sizes for ŠKODA Octavia A7
Factory wheels on Octavia A7 vary depending on the configuration and year of manufacture. Basic versions (eg Active or Ambition) are usually equipped with steel wheels 6.5Jx16 ET50 with bolt pattern 5×112. More expensive modifications (Style, L&K) get alloy wheels 7Jx17 ET45 or 7.5Jx18 ET42.
For sports version Octavia RS disks provided 7.5Jx18 ET45 or 8Jx19 ET42 with low profile tires. Important: discs from RS not always compatible with basic versions due to differences in ground clearance and wheel arch width. Below is a table with original parameters for different modifications:
| Modification | Disk size | offset (ET) | PCD (bolt pattern) | CO (hole diameter) |
|---|---|---|---|---|
| Octavia A7 1.6 MPI (base) | 6.5Jx16 |
ET50 |
5×112 |
57.1 |
| Octavia A7 1.8 TSI (Style) | 7Jx17 |
ET45 |
5×112 |
57.1 |
| Octavia RS (2.0 TSI) | 7.5Jx18 or 8Jx19 |
ET42–45 |
5×112 |
57.1 |
| Octavia Scout (all-wheel drive) | 7Jx17 or 7.5Jx18 |
ET40–45 |
5×112 |
57.1 |
Discs from Octavia A5 (Previous generation) are not suitable for A7 due to the different diameter of the hub hole (57.1 mm vs 65.1 mm for the old model). Please also note that on machines with DSG Sometimes discs with a shorter offset are installed to improve acceleration dynamics.
Permissible deviations in parameters: what can be changed?
The manufacturer allows slight deviations from the factory parameters, but with reservations. For example, offset (ET) can be reduced by 5–7 mm (for example, with ET50 up to ET43), but increasing the reach is strictly prohibited - this will lead to a shift in the center of gravity and deterioration in controllability.
The width of the disk can be increased by +1–1.5 inches from the original (for example, with 7J up to 8J), but this will require using tires with a smaller profile to maintain the outer diameter of the wheel. Bolt pattern 5×112 should remain unchanged - attempts to adapt disks with PCD 5×100 (for example, from VW Golf) lead to beating and vibration.
- 🔧 offset (ET): can be reduced by 5–7 mm, increasing is prohibited.
- 📏 Disc width: +1–1.5 inches from the original is acceptable (for example,
7J → 8J). - 🔄 Diameter: an increase of 1 to 2 inches (e.g.
R16 → R18) requires the selection of tires with a smaller profile. - ⚠️ PCD: changing the bolt pattern is unacceptable - only
5×112.
⚠️ Attention: Installing discs with offset ET < 35 to basic Octavia A7 will lead to the wheel arch touching when the steering wheel is turned completely or on uneven surfaces. This is especially true for cars with springs Sportline.

Cast, forged or steel: which is better for the Octavia A7?
The choice of disc material depends on driving style, budget and operating conditions. Steel wheels are cheaper and easier to repair, but are heavier, which affects dynamics and fuel consumption. Alloy wheels are lighter and more aesthetically pleasing, but they are less resistant to impacts (for example, from potholes) and can crack under strong mechanical stress.
Forged wheels are the most durable and lightest option, but their price is 2-3 times higher than cast wheels. They are suitable for aggressive driving or participation in track days, but for everyday use around the city they are often not justified. Below is a comparison table:
| Disk type | Benefits | Disadvantages | Recommendations |
|---|---|---|---|
| Steel | Cheap, repairable, shock resistant | Heavy, unsightly, rusty | For winter tires or budget option |
| Cast | Lightweight, variety of designs, improves dynamics | Fragile, expensive to repair, can crack due to potholes | For city use and summer tires |
| Forged | The most durable and lightest, high resource | Dear, limited selection of designs | For sporty driving or rough roads |
For most owners Octavia A7 the optimal choice would be mid-price alloy wheels (for example, from BBS, Ronal or AEZ). They offer a balance between weight, strength and design. If you often drive on rough roads, consider forged wheels or steel wheels with plastic hubcaps.
When purchasing alloy wheels, check for a certificate of conformity UNECE (labeling E with number). Discs without certification may not pass inspection.

How to properly install disks on Octavia A7: step-by-step instructions
Installing disks seems like a simple procedure, but mistakes here can lead to steering wheel beating, uneven tire wear or even spinning the wheels while driving. Follow these instructions to avoid problems:
☑️ Preparing to install disks
1. Removing old disks: Jack up the car and remove the wheel. Clean the hub from dirt and rust with a wire brush. Check the bolt threads - if they are damaged, replace them.
2. Installing a new disk: Place the disc on the hub and screw in the bolts criss-crossto avoid skew. Tighten them with a torque wrench to 120 Nm (for Octavia A7).
3. Runout check: After installing all wheels, lower the car and check for vibrations at speed. 80–100 km/h. If there is runout, perform balancing.
4. Control after 100 km: After 100–200 km, check the tightness of the bolts - they may have become loose. This is especially important for alloy wheels, which are more sensitive to vibration.
What to do if the disc does not fit on the hub?
If the disc does not fit on the hub due to a difference in the diameter of the central hole (CO), use spacer rings (hubs). They make up the difference between Disk center and hub diameter. For example, for a disk with CO 71.6 mm to the hub 57.1 mm you will need a thick ring 7 mm.
Common mistakes when selecting and installing disks
Even experienced car owners sometimes make mistakes that lead to expensive repairs. Here are the most common of them:
- 🚗 Ignoring offset (ET): Installing disks with
ET < 35to basic Octavia without modifications it will lead to friction against the arch. - 🔩 Incorrect bolt tightening: Overtightening or undertightening the bolts leads to disc deformation or wheel unscrewing.
- ❄️ Using summer discs in winter: Alloy wheels are less resistant to low temperatures and reagents, which leads to corrosion.
- 🔄 PCD Mismatch: Trying to install disks with
PCD 5×100through adapters is fraught with beating and accident.
Another mistake is buying discs “for growth.” For example, setting R19 to basic Octavia 1.6 MPI without changing the suspension will lead to a rough ride and rapid wear of the shock absorbers. If you want to increase the diameter of the discs, simultaneously install short travel springs or racks with reduced rigidity.
Discs with offset ET < 35 require wheel arches to be rolled out or spacers installed, which may affect safety and warranty.
Caring for disks: how to extend their service life?
Discs on Octavia A7 require regular maintenance, especially on Russian roads. Cast and forged wheels are sensitive to salt and reagents, while steel wheels are sensitive to corrosion. Here are some tips:
- 🧼 Washing: Use special tools for disks (for example, Sonax Wheel Cleaner) and a soft brush. Do not use abrasive pads!
- 🛡️ Protection: Apply a protective varnish or ceramic coating to alloy wheels to prevent oxidation.
- ❄️ Winter operation: Before the season, treat the discs with an anti-corrosion composition (for example, Molykote).
- 🔧 Balancing: Balance every 10,000 to 15,000. km or after a severe impact (for example, falling into a pit).
If there are cracks or chips on the disk, do not postpone repairs. For cast discs, use argon weldingFor forged – consult with a specialist. Steel discs can be restored by a richt, but with severe deformation, it is better to replace them.
Use cover or suspension systems to store seasonal discs, which will prevent deformation and corrosion. Do not fold the discs in a pile, especially if they are cast!
Frequent questions about the ŠKODA Octavia A7
Can I put VW Golf 7 discs on the Octavia A7?
Yes, but with reservations. VW Golf 7 and Octavia A7 have the same bolt pattern 5×112 and CO 57.1, but crash (ET) may vary. For example, disks from Golf R (ET45) suitable for Octavia RSBut not for the basic version. Always check the parameters!
Which wheels are better for winter: steel or alloy?
Preferable for winter steel wheels. They are cheaper, more resistant to corrosion from reagents and less affected by impacts (for example, if you hit a hole under the snow). Cast discs in winter require more careful care and risk cracking with sharp temperature changes.
What happens if you put the ET 30 on the base Octavia A7?
Discs with offset ET 30 They are strongly outward, which will lead to:
- Friction on the wheel arch at full steering wheel.
- Increased load on wheel bearings.
- Problems with passing technical inspection (departure outside the manufacturer’s tolerances).
Installation of such disks will be required rolling out arches or use spacers, which is unsafe.
How often should the discs be balanced?
It is recommended to carry out balancing:
- Every 10–15 thousand kilometers.
- After a severe blow (falling into the pit).
- When changing the tires (even if the discs were not removed).
- When vibrations appear on the steering wheel or body.
For alloy wheels use final balancing With loads on the inside, it will improve accuracy.
Is it possible to paint alloy wheels yourself?
Yes, but in compliance with technology:
- Remove the disc and clean it of the old coating (sandblast or sandpaper).
- Degrease the surface White spirit.
- Apply a metal primer (eg Body 960).
- Paint the disc with heat-resistant paint (for example, Motip) in 2–3 layers.
- Apply varnish to protect against chipping.
Do not use conventional car paint – it will not withstand the heat from the brakes!
