Help figuring out what wheel sizes I need?

How do you know what wheel sizes to go with when buying them?  I've got a 94 Honda Accord LX that I plan on buying an air runner kit for.  Problem is I'm a car audio nut, but I know nothing about wheels except what I think looks good (on the face).

I'd like to go with a staggard setup like what I've seen on this forum, but I'm really unsure on what size wheels I would need to make this idea work.  I'm in Okinawa Japan so I can ship anything JDM I could ever want back home to Houston.  17" or 18" wheels work for me...doesn't matter what size honestly as long as it won't present any problems when I let the air out.

Any suggestions or pointers on where to show this n00b?

Id use this for reference:

that was m y original post..
its my buddy's accoubnt.. he switched wheels
and he's rolling on 18x8 and 18x9 +20 all around...
its pretty insane and its getting to the point
where he needs to flare/push/pull out the fenders.

i would say in the rear.. i'd do a 18x9 +30 or +35.
and the front 18x8 +35 or so.
that would give u something that looks decent, but u gotta
do a little work. if u go any more crazy, u'll need to pull and bend out
fenders.

Id like to see pics if possible. Im thinking about one for a DD.

Neg camber will make all the difference in the world to fit the crazy wheels in

helps alot to give you a visual of how much your new setup will poke. put in the measurements and run outside with a ruler/tape measure to your fenders.
