At Tire Rack and a few other sites:
205/75R14 seems to have slightly more selections than 215/70R14. A good chunk of them seem to be trailer tires as @MoparLeo stated.
15 inch tires are not much better.
I keep forgetting how skinny these guys are. I just put on 205/65-R15 winter tires on my duster. Let me just say it just looks... funky now that I have all this rear wheel well space, but then again I'm going from 275/40R17 rear tires.
From the side she don't look too bad though, just don't look at her rear.
