Is a slight bulge in the tire a problem?

[Brooke]

A slight bulge in the tire is indeed a problem. A tire bulge occurs when the internal cords in the tire's ply layer break, allowing air to push outward from the broken cords. Without the support of these cords, the elastic rubber can bulge under the pressure of the air. When a tire bulges, it indicates that the internal cords have already broken, and continued use may lead to a blowout. External forces that can cause cord breakage include the following situations: 1. The tire experiences a significant impact, such as driving at high speed over rough roads or speed bumps with large height differences. 2. Parking the car on uneven ground for extended periods: Some drivers may park on sidewalks inside curbs to find a spot, which over time can severely affect the tire's cords, leading to bulging. 3. Driving with chronically low tire pressure: Low tire pressure puts excessive strain on the tire's ply layer, causing fatigue in the cords and eventual breakage, resulting in bulging.
