As Jay said, 205/50-16 or 225/45-16, with the correct offset. The 205's are safer since you don't know your rims' offset. I have 215/45-16's on my 16"X7.5" wheels, with an offset of ET25. No rubbin'. They're a bit smaller (in height) than stock, but it's hard to notice. If you get tires and there is rubbing, you'll need spacers.
Did you look closely on the inside of the rim to see if there is an "ET" offset stamping?
EDIT: I re-read your question and I'm not sure if you're asking about tire size again or tire brand.
