Glossy material rendering black, in a scene with environment and emission lighting

Question

Having a bit of an issue, just messing around with some game models. And whenever I apply a glossy shader it renders black, just for the car/tires model (pre modeled). Any other objects (newly created) render the glossy just fine. I have a plane with an emission shader as well in the scene.

Thanks!

EDIT: .blend file

That's because of custom split normals, related. Once they're deleted / unused the model looks as expected. Although I'm not aware of a way to render that car as glossy and have split normals used (if they are needed for some reason). — Mr Zak, Oct 23 '16 at 18:51

Deactivate autosmooth in data tab and it will be ok.

This works as well, along with clear custom split normals. Thank you as well! – Mike Oct 23 '16 at 18:56
