i would put finding a tire model, and desired diameter above finding a narrower tire, if you can find all three, then great. I wouldn't be surprised if the best tire size for mileage on your car would be the biggest diameter that doesn't hit or rub. As an example on tire model without any considerations but mileage, I think a 185/65-14 Goodyear fuel max would beat out every available 175/70-14 here dispite being a fraction shorter and wider.
