ŠKODA Octavia Tour 2006 (generation) A5) is one of the most popular models of the Czech brand in the secondary market. When choosing new wheels or tires, owners often face the question: what kind of bolt pattern is suitable for this machine? An error in the parameters can lead to vibrations, premature wear of the hub bearings or even emergency situations.
In this article we will analyze in detail Standard and permissible parameters of the squashing for Octavia Tour In 2006, we will tell you how to choose the right disks and tires, as well as warn against common mistakes. The information is relevant for all modifications: petrol (1.4 TSI, 1.6 MPI, 2.0 FSI) and diesel (1.9 TDI, 2.0 TDI) versions.
What is bolt pattern and why is it important for Octavia Tour?
Bolt pattern (or PCD — Pitch Circle Diameter) is the diameter of the circle on which the holes for mounting the wheel are located. For ŠKODA Octavia Tour In 2006, this parameter is strictly regulated by the manufacturer. The PCD nonconformity leads to:
- 🔧 Uneven load distribution It is a fast-paced rod that speeds up the wear of the bearings.
- 🚗 Vibrations at speed over 80 km/h, even if the discs are balanced.
- ⚠️ Dangers of wheel separation during emergency braking or sudden maneuver.
In addition to PCD, other parameters are important: offset (ET), center hole diameter (DIA) and rim width (J). For example, an incorrect offset shifts the wheel in or out, which affects the handling and wear of the tires.
If you buy used discs, be sure to check the PCD with a barbell - often sellers indicate the parameters "by eye".
Standard bolt pattern. ŠKODA Octavia Tour 2006: parameter table
The manufacturer sets the following parameters for all modifications: Octavia Tour (including RS and Scout):
| Parameter | Meaning | Note |
|---|---|---|
| Bolt Pattern (PCD) | 5×112 | 5 holes, circle diameter 112 mm |
| Center Hole Diameter (DIA) | 57.1 mm | Discs with DIA up to 60 mm are allowed (transition rings are used) |
| offset (ET) | 35–45 mm | For Octavia RS Possible ET 30-35 mm |
| Disc width (J) | 6.0J–7.5J | For tires with a width of 195–225 mm |
| Mounting thread | M14×1.5 | Moment of tightening of bolts - 120 N·m |
Important: parameters for Octavia Tour coincide VW Golf V, Audi A3 8P and SEAT Toledobut not suitable for Octavia A4 (PCD 4x100 there).
- Steel (stamped)
- Cast (light alloy)
- Forged

Permissible deviations: when can we depart from the standards?
In some cases, slight deviations from the factory parameters are possible, but with reservations:
- 🔄 offset (ET): allowed ± 5 mm of the standard value. For example, if the standard ET is 38 mm, you can install discs with ET 33-43 mm. But:
- ⚠️ ET < 30 mm moves the wheel outward, increasing the load on the wheel bearing.
- ⚠️ ET > 45 mm It narrows the track, impairing stability at high speed.
By disk-width (J) an extension to 8.0J is permissible, but only if:
- 📏 Tires with profiles not higher than 45% (e.g. 225/40 R17)
- 🔧 Installation of pads (if departure adjustment is required).
⚠️ Attention: Discs with PCD 5×100 (from VW Passat B6) can be physically installed on Octavia Tour, but this will lead to 2 mm mismatch of holes And uneven tightening of the bolts. The risk of wheel detachment on the road or with sharp braking is extremely high!
How to choose the right tires for Octavia Tour 2006?
The size of the tires depends on the diameter of the disk and the modification of the car. The manufacturer recommends the following combinations:
| Disc Diameter (inches) | Recommended tire size | Note |
|---|---|---|
| 15 | 195/65 R15 | Standard for basic versions |
| 16 | 205/55 R16 | Optimal balance of comfort and handling |
| 17 | 225/45 R17 | For Octavia RS or tuned versions |
| 18 | 225/40 R18 | Requires clearance check (possible grazing for arches) |
When choosing tires, consider:
- 🌡️ Speed index: for Octavia Tour minimum acceptable -
T(up to 190 km/h), but betterH(up to 210 km/h) orV(up to 240 km/h). - ❄️ SeasonalityWinter tires must have the markings
3PMSF(snowflake symbol). - 🔧 Direction of the drawingAsymmetric or directional tires require strict adherence to the installation side.
What happens if you install tires of the wrong size?
The discrepancy in the size of the tires leads to distortion of the speedometer readings (for each +10 mm diameter, ~3% is added to the speed), deterioration of handling and the risk of damage to the suspension. For example, tires 205/50 R17 instead of 205/55 R16 lower ground clearance by 15 mm, which is fraught with blows to the underwings on irregularities.
Step by step: how to measure the bolt pattern yourself
If you are in doubt about the parameters of the disks (for example, when buying used ones), you can measure the PCD manually. You'll need:
- 📏 Caliper or ruler.
- 🔨 Calculator.
For 5-hole discs (like Octavia Tour):
- Measure the distance between the centers of two adjacent holes (for example,
A = 70 mm). - Multiply the result by a factor of 1.051 (for 5 bolts):
70 × 1.051 ≈ 73.57 mm. - Round it to the nearest standard value – in our case, it’s 74 mm, but for Octavia Tour must be 112 mm.
☑️ Checking the slap before buying discs
⚠️ Attention: Some vendors refer to PCDs as "5×114.3" for versatility, but such discs are not. don't fit for Octavia Tour! The difference of 2.3 mm leads to distortion and uneven puff.
Top 5 Mistakes When Choosing Disks and Tires Octavia Tour
Even experienced car owners make mistakes. Here are the most common:
- Ignore offset (ET)ET 20 mm wheels are visually aggressive, but reduce the suspension life by 30-40%.
- Buying discs without transition ringsIf the DIA is greater than 57.1 mm, the wheel will be mounted "on the center", which will lead to a beat.
- Installation of tyres with an inappropriate load index: for Octavia Tour minimum index -
91(615 kg per wheel). - Using bolts of the wrong length: too long bolts will rest in the brake disc, short - will not provide reliable fastening.
- Neglect of balancing: even new wheels require balancing with tires (cost – from 500 rubles per wheel).
The most dangerous mistake is installing disks with a PCD of 5×100 or 5×114.3. This leads to the "stretching" of the holes and the risk of tearing off the wheel on the move.
Tuning recommendations: which discs are suitable for Octavia RS?
For sports version Octavia RS 2006 (engine 2.0 TSI) allow wider wheels and low profile tires, but with limitations:
- 🏎️ Wheels 18": maximum width - 8.0J, offset - ET 30-35 mm. Example:
8.0J×18 ET35with tires225/40 R18. - 🔧 Spacers: allowed up to 15 mm, but require elongated bolts (e.g.,
M14×1.5×40mm). - 🎨 Color: for RS pop-up
Anthracite,TitanorGloss Black.
When tuning, be sure to:
- 📋 Check the clearance (the gap between the tire and the arch should be at least 10 mm).
- 🔧 Correct the collapse-convergence after the departure change.
- ⚖️ Consider the weight of the discs: forged lighter cast by 20-30%, which improves the dynamics.
For Octavia Scout (all-wheel drive version) avoid drives wider than 7.5J - this worsens geometric cross-country performance and increases the risk of tire damage on the road.
FAQ: answers to frequently asked questions
Is it possible to install discs from VW Passat B6 on Octavia Tour?
No! U Passat B6 bolt pattern 5×112The diameter of the central hole (DIA) is 66.6 mm, not 57.1 mm. Without transition rings, the wheel will not be fixed correctly, and the bolts will not provide reliable fixation.
What kind of bolts are needed for Octavia Tour 2006?
Standard bolts have the following parameters: M14×1.5length - 27-30 mm (depending on the thickness of the disk). For disks with spacers, bolts 40-50 mm long will be required. The moment of puffing. 120 Nm.
What should I do if vibration appears after replacing the disks?
The reasons may be as follows:
- Failure to observe the moment of tightening of bolts (you need to pull the dynamometer key).
- The lack of wheel balancing (especially for 17" and 18" discs).
- Damage to the hub or bearing (diagnosis is required).
First, check the balancing and tightening of the bolts. If the vibration remains, contact the service to check the geometry of the disk.
Can I install 205/50 R17 instead of 205/55 R16?
Technically yes, but:
- The clearance decreases by ~12 mm, which can lead to blows to the suspension on irregularities.
- The speedometer will overstate the readings by ~2.5% (at a speed of 100 km / h, the real speed will be 97.5 km / h).
- Comfort is worsened due to the more rigid sidewall of the low-profile tire.
