If a tire shows sidewall damage with a visible cut or bulge, what is the recommended action?

• A. Replace the tire after inspection
• B. Continue operation until the next maintenance window
• C. Patch the tire from the outside
• D. Inflate to maximum pressure and monitor

Answer: (A)

When you see sidewall damage with a visible cut or bulge, the tire’s structural integrity is compromised. The sidewall flexes a lot and supports load, so any cut or bulge means the cords or belts could be damaged or exposed. Repairs aren’t allowed for sidewalls; a professional inspection is needed to assess the extent, but the safe course is to replace the tire. Patching from the outside or continuing to operate won’t restore strength and can lead to a sudden failure. Inflating to maximum pressure and monitoring also won’t fix the damage. Replacing the tire after inspection eliminates the risk and ensures the tire can perform safely.
