Hey, I'm looking to keep my car looking fairly factory, so I'd like to throw some 15X5.5 1995 Escort GT wheels on my '91 LX. I'm currently running on 175/70-13's (don't laugh

), and I'm wondering what size tires I'd want if I got those GT wheels. I've had 205/50-15's recommended by another Escort owner, but I'd like some more porfessional advice so I don't throw off my speedo or rub the inner fenders too much.
