I was told the same thing when I had mine mounted by Roger Kraus Racing and was unaware as well. Brandon, the son's owner, stated it becuase of the way the ply's are laid out and if backwards meaning wrong tire on the wrong side the ply end could have a small ridge which would contact the ground on the face of that ridge rather than the back side. Kinda of like a wave in the ocean you want the back side of the wave hitting the ground first not the front or face of the wave. Yes the bar code reflects the outside of the tire.

Another idea is to place a small mark on the edge of each rear tire right near the rim and another small mark on the actual rim. I was told that if you hit the pedal hard enough you can spin the rim within the tire beed, meaning your two marks will no longer line up, if this happens your tire can become unbalanced. If you have them marked you can keep an eye on this. I think its only for the first few hundred miles/heat cycles that this can happen.

Love the tires thanks a bunch Nick!
