Ferrari 488 GTB Wheel

I'm diving into my first hard surface modeling challenge, part of a bigger project that I'll share in pieces as I wrap it up. Key areas to improve: 1) The rear wheel's edge isn't perfectly flush, causing it to wobble when rotated. 2) The subsurf modifier has gone haywire, resulting in an odd crease along the model's perimeter - currently addressing this by fixing its geometry. 3) Some normals are behaving strangely or aren't present at all. 4) Smoothing shading would've been a great idea; I'm confident I can create a better-looking model with less geometry.
