Question: When performing a routine inspection of an off-road tire on a wheel loader, a technician observes a deep, localized cut on the sidewall, approximately 75 mm long and exposing the cord. The tire still holds air. What is the appropriate action?
Answer options:
- Repair the cut using a hot patch method to ensure structural integrity.
- Buffer the area and apply a cold patch as a temporary fix. ✅ Remove the tire from service immediately for professional inspection and potential replacement.
- Monitor the cut during daily inspections and only intervene if it expands or starts leaking.
Correct answer: Remove the tire from service immediately for professional inspection and potential replacement.
Explanation: A deep cut exposing the cord on a tire sidewall is a serious structural integrity issue that cannot be safely repaired by general technicians and requires immediate removal from service for expert assessment or replacement. Continuing to operate with such damage poses a significant safety risk. Hot or cold patches are not suitable for structural sidewall cord damage.
