VOLKSWAGEN GOLF CABRIO 1994 (01) PDF Document

Conversions of wheels and tyres on your VOLKSWAGEN GOLF CABRIO 1994 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 Type Approval (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’s GTA or EU operating permit/type approval may be fitted to the vehicle.

For conversions recommended by VOLKSWAGEN AG, there are no general operating permits in accordance with § 22 StVZO (German road traffic and licensing regulations).

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 the requirements of the road traffic regulations if converted.

When converting wheel and tyre combinations on your VOLKSWAGEN GOLF CABRIO 1994, adhere to the following technical conditions:

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

Approval of wheel and tyre combinations or a change to wheels from the accessories trade is not possible with the provided parts certificate.

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

If the listed wheel and tyre combinations are used, the 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 in the parts certificate are observed.

Unless otherwise stated, snow chains may only be fitted to the drive wheels.

Proper storage is crucial for maintaining the condition of the tyres on your VOLKSWAGEN GOLF CABRIO 1994.

Storage Room Conditions:

The storage room should be dark, dry, cool, and ventilated.

WARNING: Stored tyres must not come in contact with fuel, oil, grease, or chemicals under any circumstances. Otherwise, the material in the tyre will be damaged by chemical reactions which are not always visible. As a result, dangerous situations can occur when the car is driven.

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

Storage of Tyres without Wheels:

Tyres without wheels are best stored standing vertically. If tyres lie stacked for long periods, they will be pressed together, making them more difficult to fit. If 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 recommendations for your VOLKSWAGEN GOLF CABRIO 1994:

Age Limit: It is recommended not to use summer and winter tyres that are older than 6 years. The original properties deteriorate due to the ageing process, with winter tyres especially losing their adhesion properties.

Using the Spare Tyre: When new tyres are fitted, the 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 have an adverse influence on car handling.

Tyre Renewal: Tyres must always be renewed when the legal minimum tread depth of 1.6 mm is reached or if there is visible mechanical damage.

Fitting Recommendations:

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

Snow chains must be fitted to driven wheels only.

It is not possible to use snow chains with all wheel and tyre combinations. Notes on this can be found in the vehicle tables of the parts certificate.

If no particular type of snow chain is specified, then small-link chains may be used. These, including the chain fastener, may not protrude more than 15 mm beyond the wheel’s tread and the inner wall.

The maximum speed permitted by law when driving with snow chains is 50 km/h.

Snow chains should be removed when there is no snow on the road. They adversely affect the vehicle’s handling and cause unnecessary stress and wear on the tyres and chains.

To correctly measure the tyre tread depth on your VOLKSWAGEN GOLF CABRIO 1994, follow these steps:

1. The tread depth is measured in the main tread channels.

2. Do not measure at the TWIs (Tread Wear Indicators). The TWIs are small raised bars in the grooves, and their position is marked on the shoulder of the tyre with “TWI”, a triangle symbol, or the manufacturer’s logo.

3. Measure the tread depth in the main tread channel at the points where the tyre is worn most heavily.

4. Tread depth should always be measured at the deepest point of the tread channel, not on top of the TWI bars.

The bars of the TWI have a height of 1.6 mm, which is the minimum tread depth required by German law. Different values may apply in other countries.

One-sided wear is often caused by driving style but can also be the result of incorrect wheel alignment. Causes include:

Driving Style: Driving fast on roads with many curves can cause increased wear, particularly on the outer shoulder of the tyre. A rounded outer shoulder with a high degree of wear on the outer tread blocks indicates fast cornering.

Incorrect Wheel Alignment: To optimise handling, the suspension is set to specific toe and camber values. One-sided wear is especially likely if the toe and camber have not been set correctly. The most frequent cause of alignment deviation is from external influences, like hitting a kerbstone.

Toe-out or negative toe-in: The distance between the front edges of the wheels is greater than the distance between the rear edges.

Toe-in or positive toe: The distance between the front edges of the wheels is less than the distance between the rear edges.

Regular servicing of the vehicle and tyres, ensuring correct wheel alignment, and adhering to prescribed tyre inflation pressures can help prevent one-sided wear.

Vibration can be caused by tyre wear, which is not always uniform across the tread. This can cause slight imbalances. To ensure optimal safety, smooth running, and even wear, it is recommended to have the wheels and tyres balanced at least twice during the tyre’s service life.

Before Balancing Wheels:

1. Ensure the tyre pressure is correct.

2. The tyre tread must not show one-sided wear and should be at least 4 mm deep.

3. The tyre must not show any signs of damage (cuts, foreign bodies, etc.).

4. The wheel suspension, steering, and shock absorbers must be in perfect condition.

Conducting a Road Test:

If you complain of “vibration”, a road test is essential before balancing. This will help determine the nature of the vibration and the speed range in which it occurs.

1. Immediately after the road test, raise the vehicle on a lifting platform.

2. Mark the positions of the tyres on the vehicle (e.g., FL for front left, FR for front right, etc.).

3. Remove the wheels for balancing.

Proper balancing requires cleanliness and precision. Follow these steps:

1. Clean the contact surfaces, the centre of the wheel, and the recess on the inside of the wheel before mounting it on the wheel balancer.

2. Mount the wheel with the tyre on the wheel balancer.

3. Rotate the wheel and tyre on the balancer. Check that the indicator lines on the sidewall run evenly and that the body of the tyre runs true.

4. If one-sided wear, flat spots, or severe wash-out spots are apparent, balancing will not achieve smooth running; the tyre must be renewed.

5. Check the wheel for radial or lateral runout. If runout is within the specified tolerance, balance the wheel and tyre.

6. Do not use more than 60 grams of weight per tyre. If more is needed, you may achieve smoother running by match mounting the tyre and rim.

7. The wheel balancer display should indicate 0 grams.

8. After balancing, bolt the wheel to the vehicle, first hand-tightening the lowest bolt, then tightening the remaining bolts diagonally to about 30 Nm. Lower the vehicle and use a torque wrench to tighten all bolts diagonally to the specified torque.

9. Perform a final road test.

If your vehicle pulls to one side, experience shows that in 90% of all complaints, the tyres are the cause, rather than the running gear. Follow these steps to diagnose and remedy the issue:

Test Conditions and Preliminary Checks:

1. Perform a road test on a level, straight, and ungrooved road with no crosswind.

2. Check all suspension components for damage.

3. Check and correct tyre pressure.

4. Check tyres for external damage, punctures, cuts, bubbles, or flat spots.

5. Ensure all tyres are of the same type, manufacture, and tread pattern, with even wear and tread depth.

Strategic Wheel Rotation for Non-Directional Tyres:

This procedure can help compensate for lateral forces (conicity) in the 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. Perform another road test. If the vehicle now travels in a straight line, the problem is solved. If it pulls to the other side or the same side, further steps are required, such as reversing a tyre on its rim or interchanging front and rear tyres, followed by more road tests.

To ensure wheel bolts and wheels are properly secured on your VOLKSWAGEN GOLF CABRIO 1994, follow these instructions carefully.

Preparation:

1. Check that the contact surfaces on the brake disc are free of corrosion and dirt.

2. Check that the contact surface and centring seat on the inner side of the wheel (rim) are free of corrosion and dirt.

3. Ensure the concave seats in the wheel bolt holes and the threads of the wheel bolts are free of corrosion, dirt, oil, or grease.

4. Check that the wheel bolts can be easily screwed in by hand. 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.

When using a temporary spare wheel on your VOLKSWAGEN GOLF CABRIO 1994, please observe the following notes:

The spare wheel is intended only for temporary use over short distances and must be replaced by a normal wheel as quickly as possible.

After fitting, check the tyre pressure as soon as possible.

Always observe the speed warning on the temporary spare wheel (e.g., “MAX 80 km/h” or “MAX 50 mph”).

Full acceleration, hard braking, and driving fast through curves should be avoided.

Never drive with more than one spare wheel.

The use of snow chains on the temporary spare wheel is not permitted.
