Is It Normal to Have Slight Bubbling After Tire Repair?
2 Answers
Tires may have slight bubbling for various reasons, depending on the situation. Here are the relevant explanations: 1. Reason one: If the tire was not repaired promptly after being punctured by a nail or the puncture was relatively large, air may have entered the inner part of the tire. This causes air to escape from the internal puncture, resulting in slight bubbling. 2. Reason two: Incomplete tire repair can lead to air leakage. In this case, the gas inside the tire may leak out quickly, requiring re-inspection and repair of the bubbling area. During the tire repair process, the bubbles that appear are called "pinholes," which are small holes caused by high-pressure gas. When pinholes appear in the tire, it also indicates that the car tire is leaking, or there may be a flaw during the repair process, necessitating re-inspection and repair.
Having worked in the automotive repair industry for so many years, I've frequently encountered cases of slight bubbling after tire repairs. This is quite common, especially if you've used glue or sealants like tire repair fluids. Right after the repair, while the adhesive is curing, small bubbles may appear, looking like tiny blisters. But normally, these bubbles disappear within minutes and don't persist for long. The key is to monitor whether the tire pressure remains stable. After the repair, inflate the tire to the recommended pressure, wait 5-10 minutes, and then check it again with a tire pressure gauge. If everything is stable, there's no issue. However, if the bubbles keep appearing, accompanied by a hissing sound or a drop in tire pressure, it indicates a failed repair—possibly due to poor sealing or uneven glue application. This should never be ignored, as a leaking tire increases driving risks, such as a higher chance of blowouts. I recommend staying at the shop a bit longer to monitor the situation—safety should always come first. If you're doing a DIY repair at home, it's best to invest in a tire pressure monitoring tool for regular checks.
