I’m guessing you mean “brushed metal” as opposed to polished chrome, but then I don’t know the current wheel-finish lingo! ;-)

In any case, if you are ray tracing your image, you can check the option “Enable blurred reflections...” in Ray Tracing Properties of your material’s “Reflectivity” which will take more rendering time but deliver tasty brushed metals with very realistic properties.

If you are using hardware shading, uncheck your material’s “Reflectivity” and instead concentrate on (ab)using the Highlight channel. These are essentially blurred versions of your environment reflections. Open the “Environment Lighting Override” section and choose “Full Lighting” and pull the Environment Light contribution to .5 or lower, and raise the IBL effect to 1 or higher. If the material still looks too “shiny” reduce the IBL contrast. **(One note on this is that in Ray Tracing, these overrides have less effect than in Hardware Rendering if the overall Highlight Color is dark)

Oh yeah, and be sure you have created and applied Ambient Shadows to your wheels before tweaking materials. (Select your wheels then choose “Scene -> Create Ambient Shadows")
