If I can recall the stock wheel size is 165/60-14, am i correct? Wider and Lower eh. I don't know what the widest tire you can throw on a 14x6 rim is. I'd say max 195. I also think it'd be hard to find a 60 or lower profile tire for a 14 inch rim.
The best thing to do is go browse Tirerack and see what they have in store for you.

Hopefully some BB heads can provide some info. I more familiar with the 7 inch rims.
