After reading this thread I decided (i.e. ordered) to go with the GTC01's at 17 X 7.5. They have same offset (+48) as the OEM's. I have not made any other alterations to the vehicle.

Although I haven't seen an example of the hyper black finish, I like the idea that they are not too bright and still create a 'differential appearance', to use the term, relative to the Sterling Silver Metallic body. I just did not want to go to a black or gunmetal or gray. (silver but not silver)

I should have them on by end of next week. For replacement tires (after the OEMs are worn out) I will want to go with one that maximizes grip in wet weather conditions.
