Škoda Octavia A8 (2020-2026) is one of the most popular family cars in Russia, and the choice of discs for it requires attention to detail. Incorrect parameters can lead to friction on the arch, accelerated wear of the suspension or even a refusal to pass scheduled maintenance. In this article, we will understand standard wheel sizes, permissible deviations in reach (ET) and diameter, as well as nuances of selection for different modifications - from the base 1.0 TSI to charged RS 2.0 TSI.

Feature Octavia A8 — platform unification MQB with other models Volkswagen Group (for example, Golf 8 or Audi A3). This expands the choice of disks, but also adds risks: for example, disks from the disks. Audi They may not be able to reach the center hole (DIA) despite the coincidence of the bolt pattern. We analyzed the manufacturer’s data, owner’s reviews and test results to compile a safe selection checklist.

Standard wheel and tire sizes for Škoda Octavia A8

Factory parameters of wheels depend on the configuration and engine. Basic versions (1.0 TSI, 1.5 TSI) are equipped with 16-17-inch discs, while the top (2.0 TSI, RS) are 18-19 inches. Below is a table with official data for the European and Russian markets (relevant for models 2020-2026).

Modification Disc Diameter (inches) Rim Width (inches) Reach ET (mm) Bolt pattern DIA center hole (mm) Recommended tire size
1.0 TSI (85-110 hp) 16–17 6.5–7.0J 45–50 5×112 57.1 205/60 R16, 205/55 R17
1.5 TSI (150 hp) 16–18 7.0–7.5J 42–48 5×112 57.1 205/55 R17, 225/45 R18
2.0 TSI (190–245 hp, including RS) 18–19 7.5–8.0J 38–45 5×112 57.1 225/40 R18, 225/35 R19
1.6 TDI / 2.0 TDI 16–18 6.5–7.5J 45–50 5×112 57.1 205/60 R16, 225/45 R18

Important: restyled Octavia A8 FL (2026) remained the same, but new designs of standard disks (for example, the design of the new disks) appeared. "Tartan" for RS). When purchasing used disks, check them for ETLIS or Disk Wheels. There is a VIN compatibility database.

⚠️ Attention: Discs with offset ET < 38 for Octavia RS They can touch the brake system calipers. Before buying, measure the gap or use spacer rings (But that makes the scoring less reliable!)

Bolt pattern and centering hole: why 5x112 and DIA 57.1?

Škoda Octavia A8 inherited from the platform MQB standard VW Group bolt pattern 5×112 (5 holes, circumference diameter 112 mm). That's the same value. Golf 8, Audi A3 and Seat LeonIt makes it easier to find discs. However, center hole (DIA) must be strictly 57.1 mm - even a minimum deviation will lead to the beating of the steering wheel at speeds above 100 km / h.

If you find discs with DIA 66.6 (for example, from BMW or Mercedes), they can be adapted using centering rings (cost ~500 rubles). But remember:

  • 🔧 The rings must be metal (Plastic deformation when heated).
  • 📏 The thickness of the ring should not exceed 3 mm, otherwise the disc will not sit tightly on the hub.
  • ⚠️ After installing the rings, be sure to check the balance - an imbalance of more than 15 g will lead to vibrations.

To check compatibility, use the calculation formula PCD (Pitch Circle Diameter):

PCD = circumference diameter (112 mm) / cos(180° / number of holes (5))

// The result should match the parameters of the disk.

📊 Which rims do you prefer for the Octavia A8?
  • Standard (original)
  • Cast unoriginal
  • Forged
  • Tuning (wide)
  • I don't know

Which offset (ET) to choose: consequences of an incorrect value

Departure (ET) is the distance from the landing plane of the disk to its centre. For Octavia A8 valid range:

  • 🔄 ET 38–50 - safe range for most modifications.
  • ⚠️ ET < 35 risk of friction against the arch or suspension (especially on the RS with wide tyres.
  • ⚠️ ET > 50 - shifts the wheel inwards, which worsens handling and increases the load on the hub bearings.

Example: If you want to put disks 8J ET40 instead of regular ones 7J ET45, check:

  1. Clearance between the tyre and shock absorber (must be ≥ 15 mm).
  2. The position of the wheel relative to the arch at a complete turn of the steering wheel.
  3. Bearing load (at the ET < 40 It is recommended to check their condition more often).
What happens if you ignore the flight?

If ET is not correct, rubber wear (uneven tread) accelerates, fuel consumption increases by 3–5% due to increased rolling resistance, and there is a risk of wheel detachment during emergency braking (due to a shifted center of gravity).

Tip: If you are planning disk-width (for example, with 7J up to 8J), reduce the flight by 5-10 mm to preserve the geometry of the suspension. Formula:

New ET = Old ET – (New width – Old width) / 2

Example: ET45 (7J) → ET40 (8J)

Compatibility with winter and summer tires: what Škoda says

The manufacturer recommends following load-index not lower 91T (for 16-17-inch discs) and 94W (for 18-19 inches). In doing so,

  • ❄️ For winter, a reduction in the width of the tire by 10-15 mm is allowed (for example, 205/55 R17 instead of 225/45 R17) for better maneuverability.
  • ☀️ For summer prohibited use tires with a speed index lower H (210 km/h) is contrary to the requirements of scheduled maintenance.
  • ⚠️ On Octavia RS tires with index V (240 km/h) are mandatory - otherwise the speed limiter will work in the ECU.

The table below contains the recommended tire sizes for different disc diameters:

Disc Diameter (inches) Rim Width (inches) Summer tires Winter tires Load/Speed Index
16 6.5J–7.0J 205/60 R16 195/65 R16 92H / 91T
17 7.0J–7.5J 205/55 R17, 225/50 R17 205/60 R17 94V / 92T
18 7.5J–8.0J 225/45 R18, 235/40 R18 215/50 R18 95W / 93H
19 8.0J 225/35 R19 - (not recommended) 96Y
⚠️ Attention: On Octavia A8 with the system Predictive DCC (adaptive suspension) tires with a non-standard profile can cause an error ESP. For example, setting 235/40 R18 instead of 225/45 R18 This will trigger the ABS sensors.

Wheel tuning: do's and don'ts

Many owners Octavia A8 They want to put wider disks to improve the appearance. But there are some very strict limitations:

  • 🚗 Maximum disk width for non-RS versions 8.5J (with ET 35–40).
  • 🏁 For RS allowed 9J ET38but only with tyres. 235/35 R19.
  • ❌ Prohibited install disks with ET < 35 without modification of arches (rolling or installation of spacers is required).

Popular tuning options:

  1. OZ Racing Replicas (for example, UltraleggeraLightweight and durable, but require balancing every 10,000 km.
  2. BBS Forged Discs - reduce unsprung weight by 20-30%, but cost from 50 000 rubles. for the kit.
  3. Staff discs from Audi S3 They are suitable for bolt pattern, but may require layouts.

Check Compatibility with ET and DIA

Measure the gap to shock absorber and arch

Buy new bolts (if the disks are thicker than the regular ones)

Balance with weights not exceeding 10 g

Check the tire pressure (recommended 2.2–2.4 bar)

Example of a successful upgrade: owners Octavia 1.5 TSI often install disks 18×8J ET42 with tires 225/40 R18. This does not impair handling, but gives the car a more aggressive look. However, RS This option will be too narrow – there is optimally 19×8.5J ET38.

Where to buy wheels: original vs non-original

Original wheels Škoda (items start with 5E0 601 025) starting from 12,000 rubles. They are all compatible, but they guarantee 100% compatibility. Alternatives:

  • 🔹 Ronal (model R51) - popular among owners Octavia for the ratio of price / quality (~ 8 000 rubles). behind the disk.
  • 🔹 AEZ (series Le Mans) - light, but require frequent balancing.
  • 🔹 Replica (for example, OZ Superturismo) - looks like the original, but 30–40% cheaper.

When purchasing used drives, be sure to check:

  1. No cracks (especially around bolt holes).
  2. Condition of the paintwork (corrosion leads to imbalance).
  3. Geometry - roll the disc on a flat surface, it should not “figure eight”.
⚠️ Attention: Discs with Avito or Drom.ru often sold without a warranty against hidden defects. Before purchasing, ask for a photo of the back side - traces of impacts or repairs are visible there.
💡

Before purchasing wheels, check their weight: the optimal figure for 18-inch wheels is 8–9 kg. Wheels heavier than 10 kg worsen dynamics and increase fuel consumption.

Common mistakes when choosing disks and how to avoid them

Even experienced car owners make mistakes. Here are the top 5 mistakes:

  1. Ignoring the Center Hole - disks with DIA 66.6 without rings will lead to steering wheel wobble.
  2. Purchasing discs with ET < 35 for non-RS versions - friction on the arches is guaranteed.
  3. Installation of tires with non-standard profile - for example, 205/40 R17 instead of 205/55 R17 knocks down the speedometer readings by 5–7%.
  4. Using steel bolts with aluminum wheels - this causes corrosion and “sticking”. Need bolts with titanium coating.
  5. Balancing new tires only - Discs also require checking, especially after impacts.

To avoid problems, follow the algorithm:

💡

Before purchasing discs, always check the parameters with the manufacturer’s data (see the table at the beginning of the article) and conduct a test drive at a speed of 120+ km/h to check for runout.

Is it possible to install 19-inch wheels on the base Octavia 1.0 TSI?

Technically yes, but it's not recommended. The suspension of the basic version is not designed for increased unsprung weight, which will lead to accelerated wear of the shock absorbers (the service life will be reduced by 20–30%). In addition, low profile tires (225/35 R19) will make the ride harsh, and the risk of damage to the discs in the pits will increase 3 times.

Which wheels fit other VW Group models?

Compatible drives from:

  • VW Golf 8 (all modifications except GTI with brakes 340 mm).
  • Audi A3 8Y (but verification required ET - y Audi often ET 45–50).
  • Seat Leon 4 (full compatibility with PCD and DIA).
Exception: drives from Passat B8 won't fit because of something else DIA (66.6).

Do I need to change the bolts when installing new discs?

Yes, if:

  • New wheels are thicker than stock (requires longer bolts).
  • You are switching from steel wheels to alloy wheels (need bolts with a cone 60°).
  • Previous bolts show signs of corrosion or deformation.
Recommended items:
  • Original bolts Škoda: N 908 132 02 (length 27 mm).
  • Analogues: Febi 26286 or TRW JBW100.

How to check discs for authenticity (original vs replica)?

Signs of original discs Škoda:

  • Logo engraved on the inside Škoda and article number (for example, 5E0 601 025 B).
  • The weight of the disc corresponds to the passport data (±100 g).
  • The paint does not wear off when rubbed with alcohol (replicas often use cheap powder coating).
Do you have any doubts? Request a certificate of conformity from the seller or check the disc by VIN on the website Škoda.

What should I do if after installing new disks a runout appears?

Algorithm of actions:

  1. Check the balancing (even new discs may require correction).
  2. Make sure the centering rings are installed correctly (no play).
  3. Carry out suspension diagnostics - runout may be caused by wear of silent blocks or wheel bearings.
  4. If the problem persists, replace the disks (possible manufacturing defect).
Important: Runout at speeds of 80-100 km/h is more often associated with the wheels, and at 100+ km/h - with the tires or suspension.
