Question: Regarding the retreading of large off-road tires, which statement is true?

Answer options:

  • Retreaded off-road tires are generally not permitted for heavy equipment applications. ✅ The casing (body) of the tire must be thoroughly inspected for integrity before retreading.
  • Retreaded tires offer significantly less traction than new tires due to material limitations.
  • Retreading is only feasible for tires with minor tread wear and no sidewall damage.

Correct answer: The casing (body) of the tire must be thoroughly inspected for integrity before retreading.

Explanation: The casing of an off-road tire is a high-value component. For successful and safe retreading, the casing must be in excellent structural condition, free from significant damage or ply separation, and undergo rigorous inspection. Retreading is a common and economical practice for heavy equipment tires, offering similar performance to new tires if done correctly.
