some special notes before you buy, the texture on the main disk is mainly procedural, if you paid attention to the wireframe renders the are some triangles on the holes which wont cause any artifact this are used to avoid unnecessary geometry (remember you will be duplicating this model 3 times for each wheel)

 the advantages of using this particular asseet: 

ready to render; perfect balance between poly count and close up renders; also complex node trees are organized 

That's, all enjoy ;)
