It depends on the type of plane. Smaller aircraft such as the Cessna 172 only have three tires, while much bigger models such as the Boeing 747 can have up to 18.
The common factor is the three-position arrangement : one tire (or set) at the nose, and two sets of main gear, one on the right and one on the left. Some very old aircraft had tail wheels instead, because they took off and landed with the nose up.
They have 3 wheels, 2 rear and 1 front.
It depends on the size of the plane. Some small planes have only 3 wheels. Some big planes have 10 or more wheels. It depends on the plane. A Piper or Cessna commuter plane is going to have a lot less wheels than does a B-52, 747 or C-5 Galaxy.
To allow the plane to land. A plane could use pontoons as well as or instead on wheels to land on water. As a general rule though, all of then have wheels, as it would be impractical to only be able to land on water.
NO it does not have motors
They are know as the undercarriage.
The wheels allow the plane to move around while it is on the ground.
