No way to reprogram em to read correctly? I mean there must be.

A 175/65-14 tire has a diameter of 23". The factory tire is 22.4". Once again the difference isn't much, but those numbers do impact speedometer/odometer readings. Many just live with it.

It's just a very odd tire choice for the U.S. It has nothing to do with it being a 14" tire vs. a 15" tire either. Even the two tire sizes they use on the Mirage don't match perfectly. They could have picked two that did match perfectly like a 175/65-14 & a 185/55-15 (both have 23" outside diameters).
