displacement,
you can tell because you can see that the little bumps actually change the surface of the wheel, unlike bump and normal mapping which would just make it look like it's different (that and the little bumps are too high to be bump or normal maps)

as far as i can tell you make a displacement map (a greyscale map like a bump map) then you make a file node in hypershade, and plug the file node into the displacement input of the shader node
then you go to Window > Rendering Editors > mental ray > Approximation Editor
select the wheel, and assign a new subdivision or displacement node and play with the settings
(i can't remember the difference off the top of my head, or what the settings do)

it should be explained more in the help files, and again if you google "maya displacement map tutorials" or something




that's a "Ch" pronounced as a "K"

Computer skills I should have:
Objective C, C#, Java, MEL. Python, C++, XML, JavaScript, XSLT, HTML, SQL, CSS, FXScript, Clips, SOAR, ActionScript, OpenGL, DirectX
Maya, XSI, Photoshop, AfterEffects, Motion, Illustrator, Flash, Swift3D
