After work intended to address a bulge in a tire sidewall, repeat the original conditions in a safe place and check whether the symptom returns. Photograph it and note whether it followed a pothole or curb impact. Record the result before clearing codes or resetting adaptations.
Follow the maker’s procedure for drive cycles and readiness monitors. Do not try to repair a sidewall bulge; arrange a replacement and check the wheel. If the issue remains, return to the evidence instead of swapping another part.
Quick educational note
