What causes the side wall bubbles?

A sidewall bubble is just like it sounds, a bulge of air extruding from the side wall of a tire, which is as a result of air leaking into the carcass and the body of the tire.

Sidewall bubbles are brought by impact damage which occurs when the tire hits a sharp object on both high and low speeds. This occurs when the car’s weight exerts pressure on the tires during travel.

Car weight exerts enough force causing damaged inside the tire, which in turn causes the formation of small holes in the inner layers of the tires. The force can also result in small damage weakening the tire. Some of the impacts may not be felt by the driver but have a huge impact on the tire. Some of the impacts include railway road, bumps, curbs, heavy damaged roads not forgetting enormous rock debris on the road.

What can cause this damage,

There are multiple reasons for bubbles to occur the most common of them are:

  • Manufacturing defects
  • Lack of air pressure or too much load
  • Road conditions

Can the tire be repaired?

No, if your tire has developed a bulge it cannot be repaired because the structure of the tire has failed.  If it is a manufacturing defect it may be replaced under warrantee.
