ŠKODA Octavia is one of the most popular cars in Russia, and the correct selection of rims for it becomes a key point when tuning or seasonally changing tires. Error in drilling parameters (PCD, ET, DIA) can lead to vibrations, premature wear of wheel bearings or even an emergency situation. In this article we will look at all the nuances of drilling for Octavia different generations - from A4 (1996) before A8 (2026), including rare modifications of the type RS and Scout.

You will be surprised, but even official dealers make mistakes when selecting discs! For example, owners Octavia A7 often encounter a problem when disks with PCD 5×112 (like Audi) are not suitable due to the different diameter of the central hole (DIA 57.1 mm instead of 66.6 mm). We've collected the latest, field-tested data and added interactive tools so you can quickly check compatibility.

What is wheel drilling and why is it important for the ŠKODA Octavia

Drilling is a combination of three key parameters of a disk that determine its compatibility with a car:

  • 🔧 PCD (Pitch Circle Diameter) - diameter of the circle on which the mounting holes are located (for example, 5×100 or 5×112). For Octavia it is always 5 holes, but the diameter varies.
  • 📏 ET (Einpress Tief) — disc overhang (distance from the mating plane to the center of the disc). A negative offset visually “pushes” the disc outward, a positive one “sinks” it inward.
  • ⭕ DIA (Diameter of Center Hole) - hole for the hub. If it is larger, adapter rings will be required; if less, the disc will not fit.

For example, a disk with parameters 6.5J×16 ET45 PCD 5×100 DIA 57.1 suitable for Octavia A5, but will be incompatible with A7, where required DIA 66.6 mm. Error in PCD even 1 mm will lead to the fact that the disc will not sit straight: the bolts will be tightened skewed, and the steering wheel will wobble when moving.

⚠️ Attention: On Octavia A7 FL (facelift) and A8 with factory wheels 7J×17 ET51 often install disks from Audi A3 with ET45. This leads to an increase in the track by 12 mm and accelerated wear of the suspension!

Drilling table for ŠKODA Octavia by generation

Below are the official data for all generations Octavia, including rare versions. Please note: options may vary for all-wheel drive models (4×4) and sports modifications (RS).

Generation Years of manufacture PCD ET (mm) DIA (mm) Notes
Octavia A4 (1U) 1996–2004 5×100 35–45 57.1 For RS allowed ET38
Octavia A5 (1Z) 2004–2013 5×100 38–48 57.1 Scout and 4×4 require ET42–45
Octavia A7 (5E) 2013–2020 5×112 45–55 66.6 RS often comes with ET51 and width 7.5J
Octavia A8 (NX) 2020–present 5×112 40–55 66.6 For iV (hybrid) allowed ET38 with adapters

Important: On Octavia A7 and A8 with 2.0 TSI engines (for example, RS), the factory wheels have an offset of ET51, but many tuning studios install ET35–40 to widen the track. This requires a mandatory check at the wheel alignment stand!

How to measure drilling parameters yourself

If you are buying used drives or want to check compatibility, you can measure the parameters yourself. You will need:

  • 📐 Vernier calipers (for DIA and ET)
  • 📏 Ruler or tape measure (for PCD)
  • 🔨 Square (for accurate offset measurement)

PCD Measurement:

  1. Measure the distance between the centers of two adjacent holes (for example, it turns out to be 70.7 mm).
  2. For 5 holes, multiply by a factor of 1.051: 70.7 × 1.051 ≈ 74.3 mm (this is the radius).
  3. Multiply the radius by 2: 74.3 × 2 = 148.6 mm - this is PCD (rounded to 150 mm).

ET Measurement:

Place the disc face down on a flat surface. Place a square on the rim and measure the distance from the surface to the mating plane (A). Then turn the disk over and measure the distance from the surface to the inner edge (B). Offset is calculated using the formula: ET = (B – A)/2 – C, where C is half the width of the disk.

Top 5 mistakes when choosing disks for Octavia

Even experienced car owners make mistakes. Here are the most common:

  1. Ignoring DIA. Discs from VW Golf with DIA 57.1 mm not suitable for Octavia A7 (66.6 mm required), even if PCD matches. This will lead to runout and damage to the hub.
  2. Disk width not taken into account. On Octavia A5 with tire 205/55 R16 It is not recommended to install wheels wider 7J - this will increase the load on the suspension.
  3. Extreme flight. Discs with ET20 on Octavia A8 visually look aggressive, but reduce the service life of CV joints by 30–40%.
  4. Purchase without testing the car. Even if the parameters are the same, the disc may cling to the caliper or shock absorber. Always do a fitting!
  5. Savings on adapter rings. Plastic rings are cheaper than aluminum ones, but they deform under high loads.
⚠️ Attention: On Octavia RS with brake discs 340 mm (optional) standard wheels 7J×17 may not fit - minimum width required 7.5J and ET no less than 45 mm!

Disc compatibility with other VAG models

Since ŠKODA Octavia built on a platform VW Group, many discs from other brands fit with minimal modifications. For example:

  • 🚗 VW Golf 4/5/6: Compatible with Octavia A4/A5 (PCD 5×100, DIA 57.1).
  • 🚗 Audi A3 (8L/8P): suitable for Octavia A7/A8, but require adapter rings with 66.6 mm on 57.1 mm.
  • 🚗 SEAT Leon 1P/5F: identical Octavia A5/A7 according to drilling, but check the width - on Leon FR often install disks 8J, which may not fit into the arches Octavia.

However, there are nuances:

Discs from Passat B6/B7 (PCD 5×112) suitable for Octavia A7, but their ET is usually higher (up to 55 mm), which will narrow the track. This reduces stability at high speeds. For a sporty style, it is better to choose wheels with ET35–40, but then rolling out the arches will be required.

Which Audi wheels are suitable for the Octavia A8?

Discs from Audi A4 (B9) and A5 (F5) with parameters 5×112, ET40–45, DIA 66.6 100% compatible. However, models with quattro may have increased ET (up to 50 mm), which is undesirable for a front-wheel drive Octavia.

Tuning and non-standard parameters: what is possible and what is not

Many owners Octavia They strive to stand out by installing disks with non-standard parameters. Here's what's acceptable and what's dangerous:

Parameter Permissible deviations Risks
PCD Only factory! For example, 5×100 or 5×112 Bolt misalignment, vibration, thread failure
ET ±5 mm from standard (for example, instead of ET45 you can ET40–50) Suspension wear, change in handling
DIA Larger hole allowed with adapter rings Without rings - hub runout and damage
Disc width +1 inch from the standard one (for example, instead of 6.5J you can 7.5J) Clinging to arches or calipers

The following combinations are popular for visual tuning:

  • 🔥 Octavia A5: disks 8J×18 ET35 with rubber 225/40 R18 (arches need to be rolled out).
  • ⚡ Octavia A7 RS: disks 8.5J×19 ET40 with tire 235/35 R19 (check the clearances with the calipers!).
  • 💨 Octavia A8 Scout: disks 7.5J×17 ET45 with off-road tires 225/50 R17.
💡

Before purchasing wide rims, be sure to test them on your car using trial installation or 3D modeling (for example, in the program WheelFitment). Even if everything is fine according to the parameters, the disc can catch on the shock absorber when the steering wheel is turned completely.

Where to buy wheels for ŠKODA Octavia: proven options

The choice of place to purchase depends on your budget and goals:

  • 🏬 Official ŠKODA dealers: Guaranteed compatibility, but prices are 30–50% higher than the market. Suitable for original discs (for example, Swirl or Gemini for A8).
  • 🛒 Stores like "Koleso.ru" or "Tuning Shop": Wide range of replicas (BBS, OZ Racing), but check the certificates. Beware of counterfeit brands Ronal or AEZ!
  • 🌍 Foreign sites (AliExpress, eBay): 40–60% cheaper, but there is a risk of getting a disc with inaccurate PCD or ET. Order only from sellers with a rating above 98%.
  • 🔄 Used market (Avito, Drom): You can find original discs from Octavia RS half price, but check on bent and cracks (especially around the holes).

When purchasing used discs, be sure to ask:

  1. Photo of the mating plane (there should be no burrs).
  2. Video of rolling (the disc should not be “eight”).
  3. Documents (if the disc is branded, for example, BBS CH-R).
💡

Before purchasing discs from AliExpress, always check with the seller accurate PCD and ET measurements — Chinese manufacturers often round values (for example, they write ET45, but in fact ET43).

FAQ: Frequently asked questions about Octavia drilling

Is it possible to install disks with PCD 5x112 on Octavia A5 (where the standard 5x100 is)?

No! The difference is PCD even 1mm will cause the bolts to not be tightened evenly. This is fraught with the risk of the wheel coming off at speed. Use only 5×100.

What happens if you install wheels with ET 30 instead of the standard ET 45?

Reducing the offset by 15 mm will widen the track by 30 mm (15 mm per side). These are:

  • ✅ Visually makes the car wider.
  • ⚠️ Will increase the load on wheel bearings and CV joints.
  • ❌ May cause the disc to catch on the arch when fully loaded.

It is recommended not to go beyond ET ±5 mm from the staff.

Are adapter rings needed if the disc's DIA is larger than that of the hub?

Yes, definitely! Without rings, the disc will not be centered, causing:

  • Steering wheel vibrations at speeds above 80 km/h.
  • Uneven tire wear.
  • Risk of damage to the hub.

The rings must be made of aluminum (not plastic!) and fit exactly DIA hubs.

Will Skoda Superb wheels fit the Octavia A7?

Yes, but with reservations:

  • Superb 3T (2008–2015): Compatible with Octavia A5 (PCD 5×100).
  • Superb 3V (2015–present): Compatible with Octavia A7/A8 (PCD 5×112), but check ET - on Superb often worth it ET48–55.

Please note that Superb heavier Octavia, so its disks may be thicker and heavier, which will affect the dynamics.

What is the maximum diameter of rims that can be installed on an Octavia A8 without modifications?

Depends on modification:

  • Standard version: 18" with rubber 225/40 R18 (for example, Continental ContiSportContact 6).
  • RS and Scout: 19" with rubber 235/35 R19, but it is necessary to check the gaps with the calipers (on RS they are larger).

Discs 20" and more will require rolling out the arches and changing the springs/shock absorbers.
