Modern radials can be reversed in direction. The stock tires (Goodyears at least) are a-symmetrical, not directional. You obviously wouldn't want to flip a directional tire. However, you can x-rotate modern radials. I work in the tire business and we rotate back to front. Cross rotating on an open differential makes sense because one drive tire will wear faster than the other. However, back to front and you should be fine.
Just don't expect great mileage out of the OG tires.
I can't wait to get me some Advans.
