Volkswagen Polo Service & Repair 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.
