Ali : I suggest buy a new set of branded light weight rims in white, 15" are best for your city and tyre profile should be 195/55 or 60 , depends on ur use, because 55 might effect ur suspension.
Btw have u seen @N20's rims ,get something like that, those are awesome i love them , and i am sure that design would look exceptional on ur city.
And light weights arent only for racing.
Keep us updated what u go for.
