What is the reason for small bubbles still appearing after tire repair?

[LaDaniela]

The reason for small bubbles still appearing after tire repair is untimely repair or incomplete repair. The following are the specific reasons for small bubbles still appearing after tire repair: Untimely repair: Because the tire was not repaired in time after being punctured by a nail or the puncture hole is relatively large, air enters the inside of the tire, causing air to escape from the internal puncture hole, thus forming slight bubbles. After repair, observe whether the bubbles bulge. If they do not bulge, it is mostly due to air leakage, which may last for two days and will not affect the tire pressure. Incomplete repair: Incomplete tire repair causes tire air leakage. In this case, the gas inside the tire will leak out quickly. It can be resolved by rechecking and repairing the bubble position. During the tire repair process, the bubbles that appear are called "pinholes," which are small holes caused by high-pressure gas. When pinholes appear on the tire, it indicates that the car tire is leaking air, or there is a hole during the tire repair process, and it should be rechecked and repaired.
