What Causes Bulges in New Car Tires?
2 Answers
Reasons for bulges in new car tires: 1. Impact on the tire: For example, suddenly hitting a curb, quickly driving over a speed bump, or running over a large pothole can cause the tire to be violently compressed, increasing the internal air pressure and causing the weaker sidewall to bulge outward. 2. Tire quality issues: If the bulge is due to tire quality problems, you can file a claim with the tire 4S store or manufacturer. 3. Poor road conditions: Driving at high speeds over rocky roads, especially hard and rough surfaces, or protruding manhole covers can significantly impact the tires. Encountering inconspicuous but highly damaging road irregularities while driving can also cause bulges.
I just bought this car less than half a year ago and the tires already have bulges. I was so angry that I drove straight to the 4S store for a check-up. The mechanic said the most common cause is driving habits—not slowing down over speed bumps, forcing the car onto curbs, or hitting hard objects with the tire sidewalls, which can break the inner cord layers and cause bulges. Another pitfall is tire pressure. New cars often come with high factory tire pressure, and over time, hitting big potholes can lead to bulges. The mechanic suggested that the first thing new car owners should do is adjust the tire pressure and install a dash cam to review footage. If you’re always driving over curbs, it’s time to change your driving habits.
