The wheels have been balanced when the vehicle leaves the factory, but there are many different factors that affect wheel balance in normal vehi- cle driving, resulting in wheel imbalance and steering oscillation. Unbalanced wheels will af- fect the level of tyre wear. In this case the wheels should be balanced again. Wheel balance must be carried out after replacement of new wheels. Cause of vehicle vibration while driving There are many different factors that can cause a vehicle to run unsmoothly → in Tyre damage on page 192. Tyre wear is one of the causes of vibration when the vehicle is running.
Tyre wear caused by driv- ing is not evenly distributed on the surface of the whole pattern, which may make the original well-balanced tyre produce a mild imbalance, re- sulting in the uneven running of the tyre. Incorrect wheel alignment causes excessive tyre wear, impairing the safety of the vehicle. The wheel alignment should be checked by a suitably qualified workshop if tyres show excessive wear. Volkswagen recommends using a Volkswagen dealership. The driver may not be aware of this actual mild tyre imbalance through the steering wheel, which further increases tyre wear and reduces tyre life.
WARNING It is recommended to balance the tyre at least twice during the life of the tyre in order to ensure safety and ensure smooth operation and uniform wear throughout the life of the tyre. If you notice unusual vibration, or if the vehicle pulls to one side when driving, indicates that a tyre is damaged. ● Slow down your vehicle speed immediately and park your vehicle where it will not ob- struct traffic. Radial runout and lateral runout of tyres Tyre and wheel rim concentric deviation that may produce radial runout and lateral runout. ● If the tyre or rim is damaged, do not contin- ue to drive, as soon as possible contact the qualified workshop. ● Check the tyres and rims for damage.
For technical reasons, the tyre and the rim can- not be perfectly concentric. If the deviation of the relative position of the tyre and the rim is too large, it may cause the unbal- ance of the tyre to exceed the allowable value. ● If there is no visible damage, drive slowly and cautiously to the next correspondingly qualified workshop in order to have the vehi- cle checked. Volkswagen recommends using a Volkswagen dealership. If you notice unusual vibration, or if the vehicle pulls to one side when driving, indicates that a tyre is damaged. WARNING ● Slow down immediately and stop the vehicle as soon as it is safe to do so. Wheel unbalance degree ● Check the tyres and rims for damage.
Please refer to at the start of the chapter on page 186. ● Never drive with damaged tyres or tyres. Do not drive on. Seek expert assistance! If the wheel dynamic balance side more than 8 grams must be used to rebalance the wheel bal- ance block. ● If damage cannot be identified from the ex- terior, drive slowly and cautiously to the next correspondingly qualified workshop in order to have the vehicle checked.
