If a bulge does not exceed a certain size, what indication does a blue triangle provide?

A blue triangle on a tire indicates that the bulge present does not exceed a certain size and signifies that the section has been repaired without structural defects. This marking is crucial because it communicates to tire technicians and vehicle owners that while the tire had an issue, it has been addressed properly, ensuring that the repair was effective and that the tire is safe to use under normal operating conditions.

It represents a level of assurance regarding the integrity of the tire after the repair process. The presence of a blue triangle also suggests that the area affected does not pose an immediate risk of failure, allowing for continued safe use of the tire under appropriate circumstances. In contrast, indications of potential failure, immediate replacement, or warranty adjustments are not applicable in this context, as the blue triangle specifically confirms the adequacy of the repair.
