VOLKSWAGEN TIGUAN 2008 (01) PDF Document

Conversions of wheels and tyres for your VOLKSWAGEN TIGUAN 2008 must be carried out under specific legislative and technical conditions:

Legislative Conditions:

• If the wheel and tyre size, including load index and speed symbol, is listed in the vehicle’s General Operating Permit (GTA) or EU operating permit/type approval, the combination can be fitted without issue. It is not necessary for the specific combination to be listed on the registration certificate; any combination approved in the GTA or EU permit is acceptable.
• Conversions recommended by Volkswagen do not have general operating permits under § 22 StVZO (German road traffic and licensing regulations).
• If the wheels or tyres are not included in the vehicle’s GTA or EU permit, the vehicle will no longer meet road traffic regulations if converted.
• The use of genuine disc-type wheels on a vehicle to which they have not been allocated is not permissible.

Technical Conditions:

• The combinations and conversions listed in this guide refer exclusively to genuine Volkswagen disc-type wheels.
• Approval for combinations from the accessories trade is not possible with the certificate statement provided in this guide.
• Tubeless radial tyres may only be fitted to rims with a safety hump feature on the shoulder.
• Tyres with run-flat properties (reinforced sidewalls) 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 between the wheels/tyres and the wheel housing, suspension, and braking system must be ensured under all operating conditions.
• Unless stated otherwise, snow chains may only be fitted to the drive wheels. On all-wheel-drive vehicles like the VOLKSWAGEN TIGUAN 2008, only the front wheels may be fitted with snow chains.

Proper storage is essential to maintain the safety and performance of your VOLKSWAGEN TIGUAN 2008’s tyres.

Storage Room Conditions:

The storage room should be:

• dark
• dry
• cool
• ventilated

Important Safety Warning:

Stored tyres must not come into contact with fuel, oil, grease, or chemicals under any circumstances. These substances can damage the tyre material in ways that are not always visible, potentially leading to dangerous situations when driving.

Storing Complete Wheels (Tyres on Rims):

• Tyres mounted on wheels can be stored flat, stacked one upon another.
• 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 should be stored standing vertically.
• If stored vertically, it is recommended to turn them every 14 days to avoid the development of flat spots. Stacking tyres without wheels for long periods can press them together, making them more difficult to fit later.

Tyres age due to physical and chemical processes, which can impair their function. The age of a tyre is a critical safety factor.

Recommendation:

It is recommended not to use summer and winter tyres which are older than 6 years. The original properties, especially the adhesion of winter tyres, deteriorate due to the aging process. This applies even to tyres that are visually flawless or have sufficient tread depth.

Using a Spare Tyre:

When fitting new tyres, a spare tyre may be used if it is in flawless condition and not more than 6 years old. Combining a spare tyre that is several years old with new tyres can adversely affect vehicle handling.

Determining Tyre Age:

The tyre’s age can be determined from the DOT designation on the sidewall, which includes the production date.

• Example for DOT number up to 31.12.1999: DOT ….. 5 0 9 <. This means the 50th week of 1999.
• Example for DOT number from 01.01.2000: DOT ….. 0 1 0 0. This means the 1st week of 2000.

Use of Winter Tyres:

• For driving in winter conditions, it is recommended to equip your VOLKSWAGEN TIGUAN 2008 with winter tyres in the recommended sizes.
• All tyre sizes listed in the vehicle documents can generally be used as winter tyres.
• Using winter tyres can affect handling characteristics. Adapt your speed to the changed handling and road conditions. For the best possible handling, winter tyres must be fitted on all wheels.
• The suitability of winter tyres for winter operation is limited when the tread depth is less than 4-5 mm. Some countries legally require a tread depth of at least 4 mm.
• It is recommended to replace winter tyres after no more than six years, as their special “winter properties” decline with age.

Use of Snow Chains:

• Snow chains must be fitted to the driven wheels only. For the all-wheel-drive VOLKSWAGEN TIGUAN 2008, only the front wheels may be fitted with snow chains.
• It is not possible to use snow chains with all wheel and tyre combinations. Refer to your vehicle’s documentation for specific notes.
• If no particular type is specified, small-link chains that do not protrude more than 15 mm beyond the wheel’s tread and inner wall may be used.
• The maximum speed permitted by law when driving with snow chains is 50 km/h.
• Remove snow chains when there is no snow on the road to avoid adverse effects on handling and unnecessary wear on the tyres and chains.

To correctly measure the tyre tread depth on your VOLKSWAGEN TIGUAN 2008, follow these instructions:

• Measure the tread depth in the main tread channels, at the points where the tyre is most heavily worn.
• Do not measure at the Tread Wear Indicators (TWIs). The TWIs are small raised bars located in the tread grooves. Their position is marked on the shoulder of the tyre with “TWI”, a “Δ” symbol, or the manufacturer’s logo.
• The bars of the TWI have a height of 1.6 mm, which is the legal minimum tread depth in Germany. Different values may apply in other countries.
• The TWIs should not be included in the measurement. Always measure at the deepest point of the tread channel next to the TWI bars.

Rough running can have several causes, often related to tyre wear and wheel balance. Uneven tyre wear can create slight imbalances, affecting the smooth running of the wheel.

Recommendation: To ensure optimal safety, smooth running, and even wear, it is recommended to have the wheels and tyres of your VOLKSWAGEN TIGUAN 2008 balanced at least twice during the tyre’s service life.

Before Balancing Wheels:

• Ensure tyre pressure is correct.
• The tyre tread must not show one-sided wear and should be at least 4 mm deep.
• The tyre must not have any signs of damage (e.g., cuts, piercing, foreign bodies).
• The wheel suspension, steering, and shock absorbers must be in perfect condition.
• A road test should be conducted before balancing.

Conducting a Road Test:

1. Perform a road test to identify the nature of the vibration and the speed range in which it occurs.
2. Immediately after the test, raise the vehicle on a lifting platform.
3. Mark the positions of the tyres (e.g., FL for front left, FR for front right, etc.).

Balancing on a Stationary Machine:

1. Clean the contact surfaces, the centre of the wheel, and the recess on the inside of the wheel thoroughly. Dirt and rust can distort the balancing result.
2. Mount the wheel on the balancer, preferably using a centring system like VAS 5271 to ensure it is 100% centred and clamped without damage. A deviation of just 0.1 mm can result in an imbalance of 10 grams.
3. Rotate the wheel and check for even running of the tyre sidewall and body. If one-sided wear or flat spots are apparent, balancing may not achieve smooth running, and the tyre may need to be renewed.
4. Check for radial or lateral runout. If runout is within tolerance, balance the wheel. The display should indicate 0 grams.
5. Do not use more than 60 grams of weight per tyre. If more is required, “matching” the tyre and rim may be necessary.
6. Bolt the wheel back onto the vehicle, tightening the bolts in a diagonal sequence to the specified torque.
7. Conduct a final road test.

If your VOLKSWAGEN TIGUAN 2008 is pulling to one side, it can be caused by the running gear or, more commonly (in about 90% of cases), by the tyres themselves due to a phenomenon called “conicity.” Conicity is a slight asymmetry in the tyre carcass that creates a lateral force, causing the vehicle to self-steer.

Test Conditions Before Troubleshooting:

• Check all suspension components for damage.
• Check and correct tyre pressure.
• Check tyres for external damage (punctures, cuts, bubbles, flat spots).
• Ensure all tyres are of the same type, manufacture, and tread pattern.
• Perform a road test on a level, straight, and un-grooved road without crosswinds.

Remedies and Strategic Wheel Rotation:

If the complaint is justified, strategic rotation of the wheels can often remedy the issue by balancing out the lateral forces from the tyres. Mark the tyres (FR, FL, RR, RL) before you begin.

For Non-Directional Tyres:

1. Perform a road test to confirm which side the vehicle pulls to.
2. If it pulls to one side, interchange the front wheels.
3. Carry out another road test.
   • If the vehicle now travels in a straight line, the issue is resolved.
   • If the vehicle now pulls to the other side, the problem is with one of the front tyres. Proceed with further rotation steps outlined in the PDF, such as reversing one front tyre on its rim or interchanging front and rear tyres.
   • If the vehicle still pulls to the same side, the front tyres are not the cause. Interchange the front and rear tyres and test again.

For Unidirectional Tyres:

1. Perform a road test to confirm which side the vehicle pulls to.
2. If it pulls to one side, interchange the front and back wheels on the same side.
3. Carry out another road test.
   • If the vehicle now travels straight, the problem is solved.
   • If the vehicle still pulls, the next step would be to renew one tyre on the front axle and re-test, followed by the other if necessary. If the problem persists, a wheel alignment check is required.

Note: If there are large differences in tread depth, the tyres with the deeper tread should always be mounted on the front axle.

Properly changing the wheels on your VOLKSWAGEN TIGUAN 2008 is crucial for safety. Follow these instructions carefully.

Preparation for Removal/Fitting:

• Check to ensure that the contact surfaces on the brake disc are free of corrosion and dirt.
• Check to ensure the contact surface on the centring seat of the brake disc is free of corrosion and dirt.
• Check that the contact surface on the inner side of the wheel (rim) and the centring seat of the rim are free of corrosion and dirt.
• The concave seats in the wheel bolt holes and the threads of the wheel bolts must be free of corrosion, dirt, oil, or grease.
• Remove any dirt, corrosion, oil, or grease from contact surfaces, wheel hub threads, and wheel bolts as necessary. WARNING: Damaged, badly corroded, or difficult-to-remove wheel bolts must be renewed.

Fitting Wheels:

1. When fitting the wheel, screw in all wheel bolts uniformly by hand.
2. Tighten the wheel bolts in a diagonal sequence to approximately 30 Nm.
3. Lower the vehicle to the floor and tighten all wheel bolts diagonally to the specified torque using a torque wrench. Do not use an impact driver when screwing in the bolts.
