What Causes Small Bulges on the Side of Car Tires?

[McBrody]

Here are the possible reasons for small bulges on the side of tires: 1. During tire usage, frequent friction with hard objects, prolonged overloading of the vehicle, or long-term use under non-standard tire pressure can all lead to bulging. 2. If bulges appear in multiple areas of the tire, it is largely due to quality issues. Defective products caused by manufacturing defects can also result in tire bulges. Problems in the raw materials or manufacturing process, including insufficient rubber composition, can lead to inadequate hardness and thickness of the tire sidewall, causing frequent bulging. 3. Impact on the tire, such as suddenly hitting a curb, quickly driving over a speed bump, or running over a large pothole, can cause severe compression. The internal air pressure increases, and the weak sidewall may bulge outward. 4. Poor road conditions, such as driving at high speed over rocky or rough roads, especially hard and uneven surfaces, or protruding manhole covers, can significantly impact the tire. Inconspicuous but highly damaging road irregularities can also be a major cause of bulges. 5. During vehicle use, avoid parking the car tilted against curbs to prevent sharp edges from puncturing or cutting the tire sidewall. When driving over speed bumps, slow down to minimize wear and thinning of the tire sidewall, which can lead to bulges. When purchasing or replacing tires, buy from authorized dealers to ensure quality reliability.
