Tire sidewall protrusions, often appearing as bulges or blisters, indicate internal damage to the tire’s structure. These deformities are not merely cosmetic issues but represent a weakening of the tires integrity, typically arising from impacts that compromise the internal cords. For example, striking a pothole or curb at a significant speed can sever or weaken the reinforcing materials within the tire, allowing air pressure to push outwards against the weakened area, creating the visible bubble.
Recognizing and addressing these structural deficiencies is crucial for road safety. A tire with compromised integrity is at significantly higher risk of sudden failure, potentially leading to loss of vehicle control and accidents. Historically, tire design has focused on increasing durability and impact resistance to mitigate the occurrence of such damage. Modern tire technology incorporates advanced materials and construction techniques aimed at preventing internal cord damage from common road hazards.
