The original tire size is 195/75-14 or 205/75-14. The tire you're running is a little wider than stock. There's a height difference, but it's negligible.
If they don't rub, and you can live with the speedo being off a bit, you're not going to hurt anything with the tires you've got on.
175/55???? Either he's pulling your leg, or he's an idiot.
