ŠKODA Kodiaq disc parameters: slap, ET, diameter and compatibility

Selecting disks for Škoda Kodiaq A task that requires attention to technical nuances. From the correctly selected parameters depends not only the appearance of the car, but also the safety of control, suspension wear, as well as the correct operation of the systems. ESP and ABS. Even a slight deviation from factory recommendations can lead to vibrations on the steering wheel, accelerated wear of hub bearings or problems with passing inspection.

In this article we will look at all key disk parameters for Kodiaq First and second generation (including restyled versions), as well as give practical recommendations for selection. You'll know what it is. bolt pattern (PCD)why is important offset (ET)How to choose the diameter and width of the disk, and what non-obvious points to consider when buying. Particular attention will be paid to the issues of compatibility with winter tires, the effect of discs on clearance and how to avoid errors when choosing non-original models.

1. Basic parameters of Škoda Kodiaq wheels: what you need to know

Each disc for Kodiaq It is characterized by five main parameters that must strictly meet the requirements of the manufacturer:

• 🔧 Bolt Pattern (PCD) - the number of holes under the bolts and the diameter of the circle on which they are located. For Kodiaq This parameter is fixed and does not depend on the configuration.
• 📏 Disc diameter (in inches) - determines the compatibility with the tire. Nana Kodiaq The discs are 17 to 20 inches, depending on the version.
• ↔️ Disc width (in inches) - affects the stability of the car and the choice of tire width. For example, a disk. 7.5J It is designed for tires with a width of 215-235 mm.
• 🔄 offset (ET) The distance from the landing plane of the disk to its center. Deviation from the factory value even by 5 mm can lead to increased load on the suspension.
• ⭕ Center Hole Diameter (DIA) - must match the diameter of the hub or be larger (using adapter rings).

It is important to understand that the parameters of the disks for Kodiaq may differ depending on the car generation, of the actuator type (FWD or 4×4) and even from the market (European and American versions sometimes have different suspension settings). For example, discs for the version Kodiaq RS Sport suspension has different departure tolerances than the standard model.

2. Škoda Kodiaq bolt pattern: PCD and other key dimensions

For all versions Škoda Kodiaq (2017–2026) The squabbling is the same:

• 🔩 PCD (bolt pattern): 5×112 — 5 holes for bolts located on a circle with a diameter of 112 mm.
• 🔧 Bolt thread: M14×1.5 (standard for most group cars) VW).
• ⭕ DIA (center hole diameter): 57.1 mm. When using disks with a large DIA are required centering rings.

These parameters are unified for all complete sets Kodiaq, including versions with petrol and diesel engines, as well as hybrid modifications. However, there is a caveat: in some markets (for example, in the United States) there may be models with alternative bolt pattern. 5×120But for Russian and European cars, this is not relevant.

Parameter	Meaning for Kodiaq	Notes
Bolt Pattern (PCD)	5×112	Same for all generations.
Center Hole Diameter (DIA)	57.1 mm	Discs with DIA up to 72.6 mm (rings) are allowed
Bolt thread	M14×1.5	Moment of tightening: 120 Nm
Mounting type	Bolts	Not to be confused with nuts (like some SUVs).

Attention! When purchasing discs, check not only the PCD, but also mounting-hole. On Kodiaq They have a cone fit (cone angle - 60 °), which ensures the centering of the disk during tightening. The use of bolts with a flat puck or an incorrect angle of the cone will lead to wheel beat and uneven tyre wear.

3. Wheel offset (ET) for Škoda Kodiaq: why is it critical

Departure (ET) is one of the most important parameters that many car owners underestimate. It determines how much the disc is "recessed" or "protrudes" relative to the hub. For Kodiaq factory departure values vary depending on the width of the disk and the type of drive:

• 🚗 Front-wheel drive versions (FWD): ET 45-50 mm.
• 🔄 All-wheel drive versions (4×4): ET 38–45 mm (due to the wider rut).

Deviation from the recommended departure by more than ± 5 mm leads to:

• ⚠️ Increased load on hub bearings and ball supports.
• ⚠️ Deterioration in handling (the car may “scour” along the road).
• ⚠️ Incorrect system operation ESPABS sensors will read the distorted data.

Example: If you install it on all-wheel drive Kodiaq offset wheels ET 30 instead of ET 38The wheels will move outwards by 8 mm on each side. This will increase the track by 16 mm, which will lead to:

• 🔧 More rigid work of the suspension (shock absorbers will decrease).
• 🔧 Risk of hitting the tire behind the arch with a full turn of the steering wheel.
• 🔧 Accelerated wear of the outer edge of the tread.

What happens if you ignore the flight?

With a significant deviation of ET (for example, ET 20 instead of ET 45), the suspension geometry is broken so much that it may be necessary to adjust the collapse-convergence, which not all SRT will undertake to do due to the output of parameters beyond the manufacturer's tolerances. In extreme cases, this leads to the “eating” of a tire for 5-10 thousand. km.

4.Rim diameter and width: tire compatibility

Factory sizes of disks for Škoda Kodiaq Depends on the equipment and year of release. Below is a compatibility table for the most common options:

Disc Diameter (inches)	Rim Width (inches)	Recommended tire size	Applicability
17"	7.0J–7.5J	215/65 R17 or 235/60 R17	Basic equipment, winter tires
18"	7.5J–8.0J	235/55 R18 or 235/60 R18	Medium and top versions, universal version
19"	8.0J–8.5J	235/50 R19 or 255/45 R19	Sports packages, Kodiaq RS
20"	8.5J–9.0J	255/40 R20 or 275/35 R20	Optional discs, versions with adaptive suspension

When choosing a non-standard diameter, consider:

• 🔄 Hub diameter shall remain unchanged (see paragraph (see paragraph (a))57.1 mm).
• 📉 Increasing disc diameter 1 inch requires a reduction in the tire profile by ~10% to maintain the outer diameter of the wheel (otherwise the speedometer will lie).
• ❄️ For winter tires It is recommended to use discs of smaller diameter (for example, 17" instead of 19") as a high profile improves comfort and reduces the risk of damage to the disk on bumps.

Attention! On Kodiaq with adaptive suspension (DCC) installation of discs with diameter 20" and may more likely lead to Disabling the dynamic clearance change functionAs the sensors will fix the limit loads on the shock absorbers.

5. How to choose wheels for the Škoda Kodiaq: step-by-step instructions

To avoid mistakes when purchasing, follow this algorithm:

1. Determine generation and completeness your Kodiaq. For example, for Kodiaq 1.5 TSI (150 hp) 2020 and Kodiaq 2.0 TDI (190 hp) 2023 may be different recommendations on discs.
2. Check the nameplate on the driver's door It contains the permissible size of the wheels for your car. Alternative: Use online VIN selection services (e.g., ETKA or Elcats).
3. Decide what type of disks you need:
   • 🔧 Steel They are cheap, durable, but heavy (suitable for winter).
   • ✨ Cast Lightweight, a variety of designs, but afraid of hits.
   • 💪 Forged - durable and light, but expensive.
4. Convert the parameters with tables in this article or manufacturers' catalogs (for example, BBS, Ronal, AEZ).
5. Check the discs for defects:
   • 🔍 Examine the inside for cracks (especially on used disks).
   • 📏 Measure the offset and DIA with a barbell (tolerance - ±0.5 mm).
   • ⚖️ Weigh the disc - the difference in mass between the wheels on one axle should not exceed 2 kg.

Helpful tip: If you buy used discs, be sure to check them out balancing machine. Even minor deformation (e.g. from falling into a pit) can cause vibrations at speeds above 100 km/h. For Kodiaq With its heavy weight, this is particularly critical.

6. Common mistakes when choosing disks and how to avoid them

Even experienced car owners sometimes make mistakes, which later become costly. Here are the most common:

• 🚫 Ignore offset (ET). For example, installing disks with ET 30 instead of ET 45 leads to the fact that the wheel protrudes beyond the arch, and when the steering wheel is turned completely, the tire touches the fender liner.
• 🚫 DIA mismatch. If the center hole of the disk is larger 57.1 mm, but you did not use centering rings, the disc will “beat” even with perfect balancing.
• 🚫 Incorrect selection of disk width. For example, width 9.0J designed for tires 255/40 R20, and if you put a tire on it 235/55 R18, the profile will be “flattened”, which will worsen handling.
• 🚫 Purchasing discs without taking into account seasonality. For winter it is better to choose wheels with a smaller diameter (for example, 17") with a high tire profile - this improves comfort and reduces the risk of wheel damage on uneven surfaces.

Real case: owner Kodiaq 2.0 TDI installed disks 20" with departure ET 25 (instead of ET 40). After 3 thousand km, play appeared in the wheel bearing, and during inspection it turned out that the wheels protrude 20 mm beyond the dimensions of the car, which is prohibited by traffic regulations (clause 7.16 “List of faults”).

How to avoid problems:

• 📋 Always check disk parameters with manufacturer data (don't trust sellers in the market).
• 🔧 When installing non-standard drives, do wheel alignment and check your work ESP on a test run.
• 📊 Use online compatibility calculators (eg. WillTheyFit or DiskCalc).

7. Compatibility of discs with other VW Group models

Since Škoda Kodiaq built on a platform MQB, it has common disk parameters with other models in the group Volkswagen. This means that rims from the following cars will fit Kodiaq without modifications:

• 🚗 Volkswagen Tiguan (2016–present, 5×112, ET 38–45).
• 🚗 Volkswagen Atlas (American version Kodiaq, but with different tire sizes).
• 🚗 Audi Q3 (2018–present, check rim width).
• 🚗 Seat Tarraco (complete analogue on the platform).

However, there are nuances:

• ⚠️ Discs from Volkswagen Touareg or Audi Q5 have the same bolt pattern (5×112), but may differ in DIA (they have 66.6 mm instead of 57.1 mm).
• ⚠️ On Kodiaq RS with sports suspension it is not recommended to install wheels from Tiguan with departure ET 50, as this will narrow the track and impair stability.

Compatibility example: disks 18" 7.5J ET45 from Seat Tarraco will fit on Kodiaq 2021 without any modifications, since both cars have the same suspension parameters and bolt pattern.

8. Questions and answers (FAQ)

Is it possible to install wheels with a 5x120 bolt pattern on the Kodiaq?

No, this is not possible without reworking the hubs. Bolt pattern 5×120 used on some American SUVs (eg Ford Explorer), but for Kodiaq she doesn't fit. Even if you physically drill holes, this will lead to uneven tightening of bolts and vibrations.

What is the maximum diameter of disks that can be installed on a Kodiaq without problems?

For most versions the maximum recommended diameter is 20". On Kodiaq RS with adaptive suspension can be installed 21", but this will require:

• Using low profile tires (eg 275/30 R21).
• Checking the gaps in the arches (with the steering wheel turned completely or the suspension loaded).
• Possible modification of the fender liners.

Please note that discs 21" and more not certified manufacturer for Kodiaq, which may cause warranty and insurance issues.

What happens if you install wheels with an offset of ET 30 instead of ET 45?

Overhang reduction by 15 mm (with ET 45 up to ET 30) will lead to:

• Shift the wheel outward by 15 mm on each side (total increase in track by 30 mm).
• Increased load on wheel bearings and suspension arms.
• Possible contact of the tire with the arch when the steering wheel is fully turned or the suspension is loaded.
• Incorrect system operation ESP, since the ABS sensors will record the changed geometry.

If you still want to use wheels with a smaller offset, the maximum permissible deviation is ET 38 (for all-wheel drive versions).

Do I need to balance my wheels when changing tires seasonally?

Yes, balancing is required every time when changing shoes, even if the wheels were not removed from the car. Reasons:

• The tire's weight may be unevenly distributed due to tread wear.
• During storage, the discs could become deformed (especially cast ones).
• The balance weights may have fallen off or moved.

For Kodiaq with its weight being over 1.8 tonnes, even an imbalance of 10 grams on the wheel can cause vibrations in the steering wheel at speeds above 90 km/h.

Can Skoda Octavia wheels be used on Kodiaq?

No, you can't. Although both cars belong to VW Group, they have different parameters:

• Octavia has a bolt pattern 5×100 (y Kodiaq — 5×112).
• Central hole diameter Octavia — 57.1 mm (matches), but due to different bolt patterns the disks will not physically fit.
• The offset and width of the rims are also different (for Octavia usually ET 45–50, but for less vehicle weight).
