Wheel

Hey i just need a bit of feedback on a wheel i’m hoping to use in a motorbike model some time in the future. I just want to know what you think of the rim shape and materials. I’m having a bit of trouble making the rim reflective enough to resemble metal, i’ve set the reflection to full and the way it is on the inside of the rim looks pretty good imo, it just doesn’t look the same on the outer bit that matters. Heres a pic:
