This set I've just been rotating front to back. Last set I did back straight up to front, front cross to back. You can cross them if you want it doesn't matter, all that matters is the tire is mounted on the wheel correctly. The tire will say this side out. Remember the tires are asymmetrical so the drivers side will make a different tread pattern in the snow than the passenger side. Crossing the tires makes them a lot louder at highway speeds.
