Choosing the right tires and wheels for Skoda Kodiaq is not just a matter of aesthetics, but a critical aspect of safety and comfort. This large crossover has a significant mass, so choosing the wrong size can lead to suspension overload, poor handling, and even breakdown of transmission units.
Owners often face a dilemma: go with standard 17-inch wheels to save fuel or upgrade to 19-inch wheels for better looks? Each option has its own technical nuances that must be taken into account before purchasing the kit. Below we will analyze in detail all the permissible parameters and operating features.
Understanding tire markings and wheel geometry will help you avoid mistakes when changing tires during the season. It is important to consider not only the diameter, but also the profile width, disc offset (ET) and the number of mounting holes. Ignoring these parameters may make the vehicle unsuitable for use on public roads.
Official factory parameters of wheels and tires
Manufacturing plant Skoda provided several configuration options, each of which has strictly defined parameters. For basic versions, steel wheels or alloys with a diameter of 17 inches are usually offered. This is the most practical solution for Russian roads with their difficult surface and winter conditions.
Depending on the year of manufacture and level of equipment, you may find the following wheel sizes: 7.5Jx17, 8Jx18 or even 8Jx19. Wheel widths range from 7.5 to 8 inches to provide optimal support for the tire profile.
The offset (ET) parameter is one of the most critical. For Kodiaq it is usually between 45 and 52 mm. A deviation from this value by more than 3-5 mm may result in the wheel touching the arch or suspension elements when turning the steering wheel or compressing the shock absorber.
- πΏ Standard bolt pattern (PCD): 5x112, which is the same as the VW Group platform.
- π§ Center hole (DIA): 66.6 mm, requires the use of centering rings when installing aftermarket discs.
- π© Fastening: bolts or nuts M14x1.5, thread length depends on the type of disk (stamping or cast).
The factory table of acceptable sizes is as follows:
| Tire size | Disc diameter | Disc width | offset (ET) | Seasonality |
|---|---|---|---|---|
| 215/65 R16 | 16 | 6.5J | 52 | Summer/Winter |
| 235/60 R17 | 17 | 7.5J | 49 | All season |
| 235/55 R18 | 18 | 7.5J | 48 | Summer |
| 255/45 R19 | 19 | 8J | 45 | Summer/Winter |
Please note that as the rim diameter increases, the tire profile height decreases. This improves handling on asphalt, but makes the car more sensitive to potholes and bumps.
The influence of wheel size on vehicle performance
Many owners seek to install larger diameter wheels, believing that this will improve dynamics and handling. However, the physics of the process works differently: an increase in the diameter and width of the wheel inevitably leads to an increase in unsprung masses. This puts stress on the suspension and braking system, which can lead to premature wear.
When moving from 17 to 19 inches, you will notice a change in the behavior of the steering wheel: it will become more informative, but also heavier. In addition, fuel consumption will increase as the engine will spend more energy turning heavier wheelsets. This is especially noticeable in winter.
An important factor is also the effect on the dashboard. The speedometer and odometer are calibrated for a specific wheel size. If you install a tire with a different outside diameter, the speed reading will be incorrect. The error can reach several kilometers per hour, which is dangerous when driving on the highway.
β οΈ Caution: Increasing wheel size beyond factory recommendations may disable the Electronic Stability Program (ESP) and traction control (ASR) systems because the sensors will receive inconsistent wheel speed data.
If you decide to experiment with sizes, be sure to check the calculated outer diameter of the wheel. It should differ from the standard one by no more than 2-3%. This will allow you to maintain the correct operation of the on-board computer and security systems.
It is also worth considering the vehicle's ground clearance. Installing low-profile tires on large rims reduces ground clearance, which makes Skoda Kodiaq less passable. For harsh environments, it's best to stick with the stock 17- or 18-inch sizes with a high profile.

Rules for selecting winter tires for Kodiaq
The choice of winter tires for a large crossover has its own characteristics. The main rule is not to chase large disks. In winter, the priority is contact with the road and the ability to punch snow porridge. Therefore, the maximum size of the disc for winter should not exceed 17-18 inches.
A wide tire on a winter road works worse than a narrow one. This is because a narrow wheel creates more pressure on the surface, cuts through snow more easily and better holds grip on asphalt at low temperatures. For Skoda Kodiaq The optimal width of the winter tire is considered to be a range of 215-235 mm.
The type of tread also plays a crucial role. For a city where roads are often cleaned and sprinkled with reagents, studded rubber or friction type "Velcro" is suitable. For rural areas or frequent trips on uncleaned roads, it is better to choose a studded model with an aggressive tread pattern.
- βοΈ Stitched rubber: Maximum grip on ice, but noisy and aggressive to asphalt.
- π¨οΈ Frictional ("Velcro"): Comfortable, quiet, works great on snow and wet asphalt.
- π‘οΈ All-season: Compromise option, but in winter it is inferior to specialized models.
Donβt forget to check the production date of the tires. Rubber over 5 years old loses its properties even when stored perfectly. Look for a four-digit oval marking, for example, 3521 This is the 35th week of 2021.
When buying winter tires, always choose a size 1-2 inches smaller than a summer kit. This will provide a higher profile and better depreciation on a bad road.
Tire pressure and its correction
Tire pressure Skoda Kodiaq The parameter is dynamic and depends on the loading of the car. An empty car requires less pressure than a loaded car. Usually, a sticker with recommendations is on the front of the driver's door or on the inside of the gas tank hatch.
For standard loading (driver and one passenger), the recommended pressure is about 2.3-2.5 bar. When fully loaded (five passengers and luggage), the pressure should be increased to 2.9-3.2 bar. Ignoring this rule will lead to overheating of tires and their premature failure.
Tire Pressure Monitoring System (TPMS) on Kodiaq Indirect, that is, it analyzes the speed of rotation of the wheels, rather than measuring the pressure directly. Therefore, the system will not show the exact value in the bars, but only warn about the difference in diameter of the wheels caused by a drop in pressure.
Check the pressure only on cold tires, that is, after parking at least two hours or after a trip of no more than 2 km. In motion, the air warms up and the readings will be overstated, which will lead to an incorrect adjustment.
β οΈ Warning: After replacing the tires or repairing the puncture, be sure to perform the pressure relief procedure through the on-board computer menu. Otherwise, the system will issue false warnings.
In winter, the pressure should be checked more often, since when the temperature drops by 10 degrees, the pressure in the tire drops by about 0.1 bar. Regular monitoring will help to avoid uneven wear of the tread.

Features of installation and balancing
The process of installing wheels on Skoda Kodiaq It requires attention to detail. The fastening bolts must be tightened with a certain moment of force, usually 120 Nm. The use of a dynamometer key is mandatory, since untwisted bolts can unscrew, and twisted bolts can break the thread.
Before installing the disc on the hub, it is necessary to clean the seat from dirt and rust. The centering of the disc is carried out along the central hole, so it is important that it coincides with the hub protrusion. If you use disks with a large central hole, be sure to install plastic centrical rings.
Balancing the wheels is a mandatory procedure. For heavy disks with low-profile rubber, the permissible error is not more than 5 grams. An unbalanced wheel will cause the steering wheel to vibrate at a speed of 80-120 km / h, which tires the driver and destroys the suspension elements.
- βοΈ Use the original nuts or bolts that match the type of disk (cone or sphere).
- π οΈ Use lubricant for threading bolts to avoid them being stuck dead.
- π Change the wheels diagonally during the seasonal change for uniform wear.
If you install non-standard disks, make sure that there is no grazing for the caliper. Some wide low-relegation discs may touch the brake mechanisms, which will cause them to jam.
How to check if the disk is installed correctly?
After installing and tightening the bolts, scroll the wheel with your hand. It should rotate freely and silently. Then, pressing the brake pedal, check if there are any extraneous sounds. Visual inspection of the gap between the disc and the caliper is also mandatory.
Additional accessories and protection
To protect wheel arches and discs from corrosion and mechanical damage, it is recommended to use special means. Chemical treatment of arches with anti-gravel compounds will prolong the service life of the body, especially in conditions of winter reagents.
Many owners install caps on steel discs. However, quality cast discs do not require caps. If you still want to close the bolts, make sure the caps do not interfere with the cooling of the brake discs and do not have sharp edges that can tear the tire when maneuvering.
Discs with matte or glossy surface require special care. Do not use aggressive chemicals or hard brushes. For cleaning, use special shampoos for discs that dissolve brake dust without damaging the paint coating.
β οΈ Attention
β οΈ Attention
When washing a car under high pressure, keep the nozzle at a distance of at least 30 cm from the disk. A jet of water can damage the paint coating or deform the thin spokes of the alloy disc.
Regular washing of discs helps to avoid accumulation of aggressive salts and dirt that corrodes metal. Pay special attention to the inner side of the disk, where the most dirt and brake dust accumulates.
Frequently Asked Questions
Can I put R20 discs on the Skoda Kodiaq?
Physically install R20 discs is possible if they have the correct bolt pattern and flyout. However, this will require the installation of low-profile rubber (e.g. 255/45 R20), which will significantly impair comfort and cross-country performance. The plant does not provide such dimensions, so there may be a problem with passing the inspection.
What is the most popular tire size for Kodiaq in Russia?
The most popular size is 235/60 R17. This size provides the perfect balance between comfort, patency and the price of rubber. It is perfect for both summer and winter seasons on most roads in Russia.
Should I change the wheels when buying winter tires?
It is highly recommended to have two sets of discs: one for summer tires, the second for winter tires. This will save money on seasonal balancing and extend the life of the rubber, as there will be no constant installation and dismantling work that can damage the onboard edge of the tire.
How does the increase in disk width affect fuel consumption?
Increased disc and tire width leads to increased rolling resistance and aerodynamic drag. This inevitably increases fuel consumption, especially in urban cycles. The difference can be 0.5-1.0 liters per 100 km depending on the driving style.
Can I use wheel bolts from other VW models?
Yes, bolts from other Volkswagen Group models (Audi, VW, Seat) with 5x112 bolt pattern are often compatible, but you need to check the length of the thread and the type of seating part (cone or sphere). Using an inappropriate fastener can cause the wheel to unscrew.
