You can put 195/70 on them they work fine, that was my first mod. the 205 may rub and that would suck.
When you can afford some aftermarket wheels try the 16x7 they offer a lot of tire sizes. also if you go with a 195 drop the profile from 70 to 65 or 60 so that it doesnt look like your rolling on donuts. Just a suggestion...
You wont have to worry about the speedometer miss reading with the 195's-65-14
I have the 205-45-16 and they are brutal in the corners. i will moe up to the 225-40-16 next.
