I figure you'll get wear anyway...best to try and have a look and a play about and see what suits your driving style. 
I've lost count, how many times i've played with the front hubs now lol.
Tyre profile will have an effect aswell, lower profile less give in the tyre, so potentially less contact surface.
You'll get a good idea how it'll affect tyre wear as you adjust / look at final stance.
Worth noting I can't say how much quicker you'll go through tyres, correct toe and switching the wheels around to even the wear will increase the tyres life...but you'll know that anyway
