Why would you use 3 textures instead of one?
You can use one image that you can use as texture, and when creating the vertices, give them the correct UV coordinates (X-Y coordinates that define where the vertex is located on the texture).
Then you have one object with one texture, instead of 3 objects with their seperate texture (resulting in 3 textures).
That would increase framerate if you have multiple wheels on your screen.
