More Lip
though your looking for concave
....More lip anyways!
to many spokes for me but I would say A.
Assuming these are all just roughly modeled rims whats the time table on modeling one of those? Give or take 2 hour? You should take a gander at Highend3D...they have free shaders that are availible for almost every 3D program, random people build them and allow for Download. I think bringing more realism to these shots would help us decide. Theres actually 2 or 3 for Maya alone that are specifically called chrome wheel shader, Im not sure how many for what your using. I wanna say 3dsmax or softImage.
