Which materials and rim type describe the Wheel and Tire?

• A. Cast Aluminum and Split Rim
• B. Steel and Welded Rim
• C. Aluminum and Solid Rim
• D. Magnesium and Tubeless Rim

Answer: (A)

The wheel and tire on this aircraft setup are described by a cast aluminum rim paired with a split rim design. Cast aluminum gives the best combination of light weight and strength for a large aircraft wheel, plus good corrosion resistance, which is crucial for performance and durability in varied environments. The split rim design means the wheel is assembled from two halves that bolt together around the tire bead, making tire mounting, removal, and maintenance much easier on heavy gear without removing the entire wheel from the aircraft. This combination—cast aluminum and a two-piece, split rim—is a common, serviceable arrangement for large-aircraft wheels.

Steel with a welded rim would add unnecessary weight and can introduce reliability concerns due to weld integrity under repetitive stress. An aluminum wheel with a solid rim would hinder tire changes, since the-toe-in-one-piece design is harder to service. Magnesium with a tubeless rim presents a different configuration not typically used together for this setup, and magnesium carries corrosion and handling considerations that aren’t aligned with this wheel-and-tire description.
