The black/silver wheel choice seems to be an age thing. Younger people, and I'm guessing you are 25 (maybe 24), seem to like black wheels.
Us older guys are more traditional and will usually be drawn towards silver wheels.
The most important thing is to trust your gut and go with what you like the most.
Or get silver and dip them black. If you dont like the look, peel it off.
What size are you going for? I think 17s or better yet, 18s in silver would look awesome.
The more openness of the spokes lends well to the silver and getting a darker look.
You could always get the silver and paint the rim black, leaving the spokes silver.. Then it would really stand out.
18's are too much out of budget. I'm getting 17's. I'll pass on two-tone wheels, think it's tacky.
