2. Draw the Wheels
Sketch a curved line to form the roof. From the bottom of each tire, draw a straight line that curves upward to show the width of the tire. Add hubcaps to each tire by drawing an oval surrounding six curved triangles.
Place a half circle above the front tire to form the wheel well. In front of the rear tire, sketch a curved line for part of the wheel well. Smooth off the rear of the car using another curved line. Under the front end of the car, form the third wheel using a half circle and a curved line.
