Volkswagen Golf Service & Repair Manual: Swellings in the tyre sidewall
| A swelling in the sidewall of the tyre indicates that the
substructure of the carcass has been damaged. |
|
|
|
| Typical causes for such damage include, for example, driving
over kerbs at a sharp angle. |
| Pinching the tyre in this way can damage the carcass. |
| The substructure of the tyre is stretched so far that
individual fibres in the carcass may be broken. |
| The extent of the damage depends on the speed of impact, the
angle of impact, the tyre pressure, the axle load and the type
of obstacle. |
