Your parts look good for sure, pretty complex one for a first!
There is one drawback of using hires torus for the tire: hires primitives are hires for major and minor radii, resulting in a uselessly large number of facets. So you may want to create a subfile with a reduced number of segments for the small radius.
Edit: looking again at the part, I see that a torus wouldn't match tire shape anyway, so my previous comment is mostly pointless
