The selection of 16" wheels that fit our cars isn't very big, but Konig makes some pretty nice ones and are pretty lightweight:

The following models are the 16's that will fit our cars. They all come in 16x7.5, +45, 5x100:
Lockout - gloss black, 16.89 lbs
Tandem - graphite, 17.39 lbs
Runlite - matte grey or matte black, 17.75 lbs
Oversteer - gloss black, 17.6 lbs
For tires...
- 205/55/16 matches stock diameter, wheel width range 5.5-7.5"
- 225/50/16 matches stock diameter, wheel width range 6-8" (less stretch; more curb protection)
- 215/55/16 gives extra 0.3-0.5" inches in diameter depending on brand/model, wheel width range 6-7.5"
I personally run 225/50/16 on both my 16x7.5 winters and 16x8 summers.
