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.
