You are going to be looking at around anywhere near a +40 offset.

Wheel pattern on a Civic is 4x100

Most common sizes

15x6" or 6.5" wheel w/195/50/15 to 205/50/15 tire
16x7" wheel w/205/45/16 tire
17x7" wheel w/205/40/17 tire
18x7" wheel w/205/35/18 tire

tire is measured like this:

205=width in mm
45=measure of inside diameter where it meet rim to outside diameter where it meets pavement in % of the width
16=size of rim for tire

I don't recommend anything over 16". Too big and too heavy.
