Airplanes are definitely fascinating, especially classic models like the Boeing 747! A 747 airplane has 18 wheels in total. There are four wheels in each landing gear assembly. There are two landing gear assemblies on each side of the aircraft, meaning the 747 has a total of four landing gear assemblies with 16 wheels. Additionally, there are two more wheels at the nose of the aircraft for landing.
This is quite a few more wheels than the average airplane—the overall average number of wheels on an airplane is only six. The reason for this is the size of the 747. The 747 is a very large commercial plane designed to accommodate more seating space than the average plane.
