The wheel and tyre combinations and conversions listed in the individual vehicle tables apply exclusively to genuine Volkswagen wheels. Wheel approval or refitting to non-original...

Tyre speed ratings
Speed index (eg "T") after the tire size marking (eg 185/ 65 R 14 86T) indicates the maximum speed allowed (vmax) for a given tire. Tyres for the respective vehicle must be...

Composite disks
Composite discs consist of several parts. The most important are the rim and the wheel disk. These parts are fastened to each other with special bolts using a special technology....

Tire wear and mileage
General information All sorts of requirements are placed on the tire. Each of these requirements is incorporated into the tire to a certain extent. Depending on the operation and...

High-speed tire wear
These tires are designed for the highest speeds. Therefore, when developing these tires, good grip on wet road surfaces comes first. The rubber compounds of the treads of such...

Tire maintenance
Tire air pressure The weight of the vehicle flattens the tire on the area of its contact with the road. The rolling of the tire leads to forced deformation of the tread and the...

Evenly worn tires
Requirements for tires are constantly becoming more stringent. The reasons are the following factors: increasing vehicle weight; high speeds; high traffic safety. High load on a...

Measuring the tread depth
Note: Measurements to determine the tread pattern height should be taken in the main tread grooves. Note: Do not measure on TWI (Tread Wear Indicator means. tread wear indicator)....

One-sided tire wear
The cause of one-sided wear in many cases is driving style, but sometimes also incorrect wheel alignment. Increased lateral wear Fig. 4.6. Example of lateral tire wear Lateral...

Diagonal uneven wear
Diagonal uneven tire wear Fig. 4.10. Diagonal uneven tire wear Diagonal spots of uneven wear run at an angle of approximately 45° relative to the circumferential direction of the...

Tire rolling noise
General information about rolling noise Rolling noises perceived by the human ear are vibrations emanating from the sound source and reaching the ear through the air. What is...

Wheel balancing
Before you begin balancing, the following conditions must be met. The air pressure in the tire must be normal. The tread pattern must not have one-sided wear, and its depth must...

Radial and lateral runout of wheels and tires
Radial and lateral runout occurs due to imprecise rotation of the disc and tire. 100% rotation accuracy is not possible due to technical features. Therefore, the manufacturer...

Minimization of mounted wheels
General Provisions If the radial or lateral runout of the disk and tire overlap, the wheel runout increases. 100% rotation accuracy is not possible due to technical features....

Lateral vehicle pull
Taper Conicity is caused by a slight offset of the tread and/or breaker relative to the geometric center of the tire by a few tenths of a millimeter. Conicity is not visually...

Eliminating lateral drift
Conditions for checking before and during the test drive Check all front and rear axle suspension components for damage. Check and adjust tire pressure if necessary. Check the...

Tire damage
General instructions Damage to tires can have serious consequences, so the driver and the vehicle service technician should regularly check their condition to detect possible...

Radial tire construction

Loss of air pressure in tires
Note: It is not recommended to repair radial steel cord tires that have carcass damage caused by a foreign object. Note: Corrosion may occur on the steel wire. This will cause the...

Tyre damage due to errors during tyre fitting (fitting damage)
The bead core ruptured while inflating the tire Fig. 4.26. Diagram of tire mounting on a disk: 1 - hump (double hump H 2); 2 – rim flange; 3 – inner shoulder of the rim (eg...

Tyre sidewall markings
Fig. 4.29. Tyre sidewall markings: 1 – dimension marking; 2 – manufacturer (trade name); 3 – tread pattern designations; 4 – tubeless tire designation; 5 – radial design; 6 –...

Wheel rotation
In front-wheel drive vehicles, due to the greater load on the front tires, tread wear occurs earlier than that of the rear axle tires. To equalize the service life of all 4 tires...

General provisions for wheel alignment (WAA) of the Passat
Wheel alignment may only be performed using a wheel alignment device approved by VW/AUDI. Each time the wheel alignment angles are adjusted, the wheel alignment angles of the...

Front axle wheel alignment correction
Note: Camber correction is only required after body repair. Camber is not adjustable, but it can be equalized on both sides by moving the consoles and/or subframe Note: The...

Rear Axle Camber Adjustment
Fig. 4.34. Nut of the threaded connection of the upper transverse arm with the subframe Loosen the nut of the threaded connection of the upper wishbone to the subframe (Fig....

Rear Axle Wheel Alignment
Loosen nut 1. Fig. 4.36. Eccentric bolt and adjusting nut Rotate eccentric bolt 2 until the nominal value is obtained (Fig. 4.36). Tighten the nut.
