Tire Wear (More inside or outside?)

Tire Wear (More inside or outside?)
So I have a set of old RA1's (yes old) that have one edge worn significantly more than the other. These didn't come off my Miata (I'm a poor tire beggar!)
What I'm wondering is, should I put these on my Miata with the worn edge inside or outside? Here my Miata setup:
- koni yellow, 550F / 340R
- hollow RB bar up front, no rear bar
- ~1.5 front camber, 1.25 rear camber
- zero toe front/rear
Thanks

I'd say what is more important to consider is how much toe you're running. Thats the true killer of tires (as far as the inside/outside argument). You probably still want to run the worn edge on the outside regardless though.
I've heard that running tires in the incorrect rotation direction periodically will help them wear evenly as well.

>=12" front ride height (measured hub center to fender)
>=4.5" front ride height measured at forward most straight section of pinch weld with 205/50/15 or 225/45/15 tires
Front camber: -2* (or as close as you can get to it)
Caster: +3.75 to +4.25*
Front total toe: 0
Rear camber : -1.8*
Front total toe: 0
<=12.0"

Works for me (I use the second setup)..
PS, I'd mount the worn edges on the "outside".

Thanks guys, it really seems like it is a bit of a crap shoot on what side to mount the worn edges. I don't really have a bunch of camber and no toe, so inside wear should be low.. but there is also good camber gain through the travel so outside wear should be low as well.
So relatively even wear.. which means these tires won't last me all that long, ha (worn edges will wear too.. eventually cording).

Back in my learner years I ran a 03 with just Yellow Konis and "old FM-springs". I needed to flip the tires twice to make the most of the rubber. With the modified LCAs (moved lower ball joint) and the -3.2 I run now the wear is even and I can just move wheels according to the wear at the track (LF is always punished the most on our tracks).
