Is slight bubbling normal after tire repair?
2 Answers
It is not normal to have slight bubbling after tire repair. The following are the possible causes of bubbling: Cause 1: It may be due to the fact that the tire was not repaired in time after being punctured by a nail or the puncture hole was relatively large, allowing air to enter the inside of the tire. The air then escapes from the internal puncture hole, forming slight bubbles. After the repair, observe whether the bubbles bulge or not. If they do not bulge, it is mostly caused by air leakage, and this phenomenon may last for two days without affecting the tire pressure. Cause 2: Incomplete tire repair leads to air leakage, which can cause the gas inside the tire to leak out quickly. In this case, the bubbling area needs to be rechecked and repaired. 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 also indicates that the car tire is leaking air.
I remember when I was just learning to drive, I noticed slight bubbling after a tire repair, which felt off because bubbles usually indicate an incomplete seal at the patched area, meaning air is still leaking. This isn’t normal—it could be due to a loose patch or cracks from tire aging. I ignored it and drove for a while, only to find the tire flat again the next day. A shop inspection revealed the repair had failed and needed redoing. Since then, I’ve made it a habit to press the patched area a few times to check for bubbles and verify the tire pressure, as overinflation can also cause issues. I suggest you do the same—don’t delay, as the risk of a blowout increases, and safety comes first. If you spot bubbles, avoid driving and contact the repair shop immediately for a rework. It’s cheaper and less hassle—learn from my mistake.
