A crane's tires should be checked for__________.

• A. Tread pressure and condition
• B. Tread depth only
• C. Tire color
• D. Tire age

Answer: (A)

Proper tire care on a mobile crane hinges on both tread condition and correct inflation. The tires carry the crane’s weight and keep it stable on uneven work surfaces, so worn or damaged tread can reduce traction and increase slipping or skidding risks. At the same time, accurate tire pressure is essential for safe handling and load distribution—underinflated tires can overheat and fail under load, while overinflated ones reduce the contact area with the ground and worsen stability. So checking tread wear and overall tire condition together with the right pressure ensures the crane sits firmly and moves safely. Tread depth alone misses pressure issues; tire color isn’t related to safety, and tire age doesn’t reflect current condition by itself.
