i've worked at a tire shop (sears auto) for about 4 yrs. i was a tech for 2...i've just about done every combo with white.
car color:
black,red,white,silver,blue,teal,green,gold,custom colors too etc....
in my opinion it only looks good on a white car. now that i have a white car i still woldn't do a white rim...it's just not my taste. but that's just me i guess..
