Stick to standard tire size, 16 inches will look good but will effect fuel economy and ride will be effected as aspect ratio will decrease and more bumps will be felt inside car.
Secondly, if buying after market then don't go for heavy ones as they will increase un-sprung mass which effects suspension.
You can also go for pre-face lift OEM alloy rims, they will cost less.
For tires, go for Yokos or Continental. Continental will be hard to find as there isn't any official dealer in here.
