A tire bulge, sometimes referred to as a sidewall bubble, is a deformation on the outer surface of a tire, presenting as a raised area that deviates from the tire’s normal contour. This occurs when the internal structure of the tire has been compromised, allowing air pressure to push outwards against the weakened area. As an example, consider a tire encountering a deep pothole at speed; the resulting impact can fracture the internal cords, leading to a localized bulge.
Understanding the causes and implications of a tire bulge is crucial for vehicle safety and maintenance. A compromised tire is significantly more susceptible to a sudden and catastrophic failure, increasing the risk of accidents. Historically, tire technology has focused on enhancing structural integrity to mitigate the occurrence of such damage. Modern tire designs incorporate reinforced sidewalls and advanced materials to improve resistance to impacts and road hazards.
