VOLKSWAGEN SCIROCCO 2009 (01) PDF Document

Tyres on your VOLKSWAGEN SCIROCCO 2009 are high-tech products adapted to the requirements of modern vehicles. To ensure safety, performance, and comfort, they require proper care, maintenance, and service. All tyres recommended by Volkswagen have been tested and designed specifically for each model in collaboration with tyre manufacturers.

Key points to remember:

• Differing speed ranges, winter and summer use, and wet/dry road conditions are all considered to find the optimal compromise for vehicle safety.

• Proper adjustment of the axle geometry during wheel alignment is crucial for ensuring the maximum service life of the tyre. The wheel alignment must always be within the specified tolerance range.

• Normal wear and tear on a tyre will alter its characteristics, which can result in rolling noises or rough running. These are symptoms of normal wear and do not constitute a defect.

Conversions of wheels and tyres can only be carried out under certain conditions. The following points must be observed:

• If the size of the wheel and tyre, including the load index and speed symbol, is included in the vehicle’s General Operating Permit (GTA) and EU operating permit/type approval, this combination can be fitted without any problem.

• It is not necessary for the wheel and tyre combination specified in the registration certificate to be fitted. All combinations approved in the vehicle GTA or EU operating permit may be fitted.

• Unless the wheels and/or tyres are included in the relevant vehicle GTA or EU operating permit/type approval, the vehicle will no longer meet road traffic regulations if converted.

• The listed conversions meet Volkswagen’s requirements for road handling and safety and are the result of practical trials.

Technical Conditions:

• The wheel and tyre combinations and conversions listed refer exclusively to Volkswagen genuine disc-type wheels.

• Approval of combinations with wheels from the accessories trade is not possible with the certificate statement.

• Tubeless radial tyres may only be fitted to rims with a safety hump feature on the shoulder.

• Tyres with run-flat properties may only be used on disc-type wheels with an extended hump and on vehicles with a tyre pressure monitoring system.

• Associated tyre inflation pressures must be adhered to. These can be found on the sticker inside the tank flap or in the vehicle’s tables.

• Sufficient clearance to the wheels and tyres at parts of the wheel housing, suspension, and braking system is assured if the notes and specifications are observed.

• Unless otherwise stated, snow chains may only be fitted to the drive wheels. On all-wheel drive vehicles, only the front wheels may be fitted with snow chains (with the exception of the Touareg).

The sidewall of a tyre contains important information. Here is an explanation of the typical markings:

1. Size code: e.g., 205/55 R 16.

2. Position of TWIs (Tread Wear Indicators): Shows where the wear indicators are in the tread.

3. Manufacturer (trade name): e.g., Continental.

4. Construction: “Radial” for radial cord direction and “Tubeless” for tubeless tyres.

5. Load capacity index / speed rating: e.g., 91 H.

6. Specified direction of rotation/installation: For directional tyres.

7. Maximum permissible load: Data for North America.

8. Maximum permissible tyre pressure: Data for North America.

9. Number of plies: Information on the plies in the tread and sidewalls and their material.

10. E number: Approval number indicating the tyre fulfils European guidelines.

11. Manufacturer code / date of manufacture (DOT): Plant, size, model, and date of manufacture.

12. DOT – Department of Transportation: Tyre fulfils standards of the US Department of Transportation.

13. Marking for Brazil

14. Marking for China

15. Country of origin: e.g., Made in Germany.

16. Safety notes: For use or fitting of the tyre.

17. Abrasion resistance: Relative expected service life based on a US standard test.

18. Wet-braking traction rating (A, B, or C): According to a US test.

19. Temperature resistance rating (A, B, or C): According to a US test.

20. Identifying tyres with run-flat properties: e.g., self-supporting run-flat.

21. Tread pattern: e.g., ContiPremiumContact.

The codes on your tyre provide detailed information about its specifications.

The load rating, or load index (LI), is found on the sidewall of the tyre and indicates the maximum load that the tyre can bear. The following table shows the load rating codes used at VW with their corresponding load capacities.

Proper tyre storage is important to maintain their condition and safety.

Storage Room Conditions:

• Dark

• Dry

• Cool

• Ventilated

WARNING: Stored tyres must not come in contact with fuel, oil, grease, or chemicals under any circumstances. The tyre material can be damaged by chemical reactions that are not always visible, which can lead to dangerous situations when driving.

Storing Complete Wheels (Tyres on Rims):

• Tyres mounted on wheels can be stored flat, stacked one upon the other.

• Ensure the tyres are clean and dry before storage.

• The inflation pressure should be increased to a maximum of 3 bar.

Storing Tyres without Wheels:

• Tyres without wheels are best stored standing vertically.

• If tyres are stored standing vertically, it is recommended to turn them every 14 days to avoid flat spots.

Tyres age due to physical and chemical processes, which can impair their function. Here are key points regarding tyre ageing:

• Even visually flawless, new, or barely used tyres older than six years may show a significant reduction in wet properties and winter suitability.

• Tyres stored for long periods harden and become brittle faster than tyres in constant use.

• The age of the tyre can be determined from the DOT designation on the sidewall.

How to read the DOT number for production date:

• Until 31.12.1999: The last three digits represent the week and year. For example, “509” means the 50th week of 1999.

• From 01.01.2000: The last four digits represent the week and year. For example, “0100” means the 1st week of 2000.

Recommendation:

• It is recommended not to use summer and winter tyres which are older than 6 years. Winter tyres especially lose their adhesion properties with age.

• When fitting new tyres, the spare tyre may be used if it is in flawless condition and not more than 6 years old.

• For safety, tyres of the same make and with the same tread pattern should be mounted on one axle.

If your vehicle pulls to one side, it can be caused by the running gear, but experience shows that in 90% of cases, the tyres are the cause due to a characteristic called “conicity.” Follow these steps to diagnose and remedy the issue.

Test Conditions Before Road Test:

1. Check all suspension components on the front and rear axles for damage.

2. Check tyre pressure and correct if necessary.

3. Check tyres for external damage (punctures, cuts, bubbles, flat spots).

4. Ensure all tyres are of the same type, manufacturer, and tread pattern.

5. Perform the road test on a level, straight, and un-grooved road without a crosswind.

Troubleshooting with Strategic Wheel Rotation (for Non-Directional Tyres):

1. Perform a road test to determine if the vehicle pulls to one side and, if so, which side.

2. If it pulls, interchange the front wheels.

3. Carry out another road test.

• If the vehicle now travels in a straight line, the problem is solved.

• If the vehicle now pulls to the other side, proceed to the next step.

• If the vehicle still pulls to the same side, interchange the front and rear tyres and re-test.

4. If it pulls to the other side, reverse one front tyre on its rim (so the direction of rotation is reversed) and re-test. If it still does not travel straight, interchange the front and rear wheels again and re-test.

For Unidirectional Tyres:

1. Perform a road test to determine if the vehicle pulls.

2. If it pulls, interchange the front and back wheels on the same side.

3. Carry out another road test.

• If it travels straight, the problem is solved.

• If it still pulls, first renew one tyre on the front axle and re-test. If the issue persists, renew the other front tyre.

4. If the vehicle still does not travel in a straight line after these steps, check the front and rear wheel alignment.
