Volkswagen Polo Service & Repair Manual: Flat Spots
| What is a Flat Spot From Standing? |
| Terms like flat portion, flattening, are also used as a term
for flat spots from standing. |
| Flat spots from standing cause vibration, like an
incorrectly balanced wheel. It is important to recognize a flat
spot in the tread from standing as such! |
| Flat spots from standing cannot be corrected by balancing,
and can occur again at any time under various circumstances.
Flat spots from standing can be corrected without complicated
special tools. Providing that the flat spot was not caused by
wheel lock during hard braking. Refer to
→ Chapter „Wear Spots“. |
 Note
| Wear spots due to wheel lock are irreparable! Tires with
such damage must be replaced. |
| Causes of Flat Spots from Standing: |
| The vehicle stands for several weeks in a location without
being moved. |
| Tire pressure is too low. |
| The vehicle was placed in a paint system drying cabinet
after painting. |
| The vehicle was parked with warm tires in a cold garage or
similar for a long time. In this case, a flat spot can develop
overnight. |
