At first I just thought the "star" was an abstract pictorial, but after I have read your comment it gets a little more clear. Maybe you should try to make it look a little more like a wheel - but not too obvious!
We see many companies in the automotive industry with cars/wheels in the logo, so it really has to be special with this approach. But it is also very important not to give our customers the impression that we are a wheel-company. We have many different products ranging from car audio, styling, performance and everyday items.
Maybe #4 is a little too simple. #5 looks a little more interesting.
You might want to try to make the font more "special" though.
