Does a slightly bulging tire need to be replaced?

[Jon]

Tires with slight bulges need to be replaced. Below are the reasons for tire bulges: 1. Tire quality issues: Uneven distribution of cords or insufficient cord strength can cause bulges. This occurs under normal driving conditions and is considered a tire quality issue. In such cases, the tire manufacturer will provide a replacement. 2. External impact: Bulges are often caused by external forces, such as squeezing or impact. For example, parking too close to the curb and squeezing the tire against it, or driving directly onto the curb can compress the tire sidewall, leading to excessive deformation and cord breakage. Additionally, not slowing down when going over speed bumps or potholes can cause sudden impacts, resulting in breakage due to sudden excessive deformation.
