| What is a tyre deformation due to stoppage? |
| To define the deformation phenomenon, synonyms as depression
and flattening are similarly used. |
| The deformations cause drive instability too, such as a wheel
incorrectly balanced. The important is the identification of a deformation
on the tyre tread. |
| The deformations cannot be eliminated through balancing and
can have different causes. It is possible the elimination of deformations
without the use of special tools. We take as principle that it is
not a deformation caused by a sudden braking → Chapter. |
Note | The deformations caused by braking are not serviceable damages
on the tyres! The tyres with this type of damages have to be replaced. |
| t
| The vehicle is stopped for several weeks in the same place,
without motion. |
| t
| The tyres have a pressure too low. |
| t
| After painting, the vehicle was put in a drying chamber of
a body and painting shop. |
| t
| The vehicle was parked for a long time with warm tyres in a
cold garage or in a similar place. In this case, a deformation can
arise from one day to another. |
| t
| The deformations cannot be eliminated from the tyres with the
means of a repair shop. |
| t
| The only way to eliminate the flattening is through tyre warm-up
during the motion of the vehicle. |
WARNING | t
| Do not expose yourself or other persons to danger during the
driving test |
| t
| Respect the traffic laws, and the imposed speed limits. |
|
| –
| After the vehicle driving test raise the vehicle immediately. |
| –
| Disassemble the wheels from the vehicle. |
| –
| Balance the wheels at the stationary balancing machine → Chapter. |
