First off, I've browsed through hundred of posts/threads about wheel fitment, but i cant seem to get a straight answer for the following question:

On a bone stock 1995 S14 SE, what are the widest/most flush wheels I can run without running any spacers while leaving the fenders/liners virgin?

Also, I'm not interested in stretching tires. In fact, I want to run a wider tire, so the wheels dont get scratched.

Oh yes, and one more thing, I want to run 4 equal size wheel and tires.

This car is a "community" daily driver in my family (even though its under my name and I drive it the most). Senior citizens and clueless women drivers tend to drive this car on occasion.
