Volkswagen Touran Service Manual: Tire Sidewall Swelling
| A swelling in the flank of the tire indicates that the
substructure of the carcass has been damaged. |
|
|
|
| Typical causes for such damage include, for example, driving
over curbs at a sharp angle. |
| Pinching the carcass of a tire this way can damage the
carcass. |
| The substructure of the tire is stretched so far that
individual fibers in the carcass may break. |
| The extent of the damage depends on the speed of impact, the
angle of impact, the air pressure, the axle load and the type of
obstacle. |
