Why Do Tires Develop Bulges?

[ElliotMarie]

When the cords in the tire's sidewall ply break, the internal air escapes through the broken cords, barely supported by the thin rubber layer, which causes the tire to bulge. Tire bulges pose significant safety hazards. Once a bulge is detected, the spare tire should be immediately installed, and the vehicle should be driven to a repair shop for tire replacement. Reasons for tire cord breakage: Tire quality issues: If the bulge is due to tire quality problems, a claim can be filed with the tire manufacturer. Tire impact: Strong impacts, such as driving at high speeds over rough roads or speed bumps, can cause cord breakage. Drive carefully. Insufficient tire pressure: Low tire pressure compresses the tire's ply layer. Driving with insufficient pressure can fatigue the ply, leading to cord breakage. Maintain proper tire pressure. Tire maintenance: When parking, choose flat surfaces to avoid excessive wheel compression. Regularly clean hard objects from tire treads using a thick, L-shaped wire hook for daily maintenance. Tires gradually age during use. If noticeable cracks appear on the tire sidewall, it indicates significantly reduced tire strength, increasing the risk of bulges and blowouts. Replace cracked tires promptly.
