Problem: One of the tires of the dump truck had two lateral cuts, which reached the metal mesh and may have been caused by stone impact during movement. It was necessary to repair the affected area in order to prevent the cut from expanding and the tire to become useless before the end of its useful life. Lateral cuts measured 130 mm and 500 mm in length and 40 and 60 mm in depth.
