Volkswagen Golf Service & Repair Manual: Undulations
| Radial depressions are slight concavities in the tyre
sidewall. |
| They run from the bead towards the shoulder of the tyre.
These parts appear in the figure
→ Fig.. |
| The cause is the accumulation of material at the joints of
the tyre components. |
| Undulations have no effect on: |
| Other characteristics of the tyre. |
| Undulations are visible to varying extents. It is not
necessary to inspect the tyre or remove it from the rim. |
| Modern steel belted tyres are constructed with single-ply
side walls to save weight. |
| The sidewall components consist of long strips before they
are joined together to form a tyre. They must overlap at the
joints. Consequently, slight irregularities or waves are created
in the area of the overlapping parts. The overlaps are easier to
see from the outside due to the single-ply construction. |
