No, they are all the same. All dually wheels are "hub centric" meaning they are aligned by the hub, not the lug nuts. That's why the tight fit around the centers. The only difference is the side you mount the skins on.
On second thought, I realized the confusion comes from the tires having to be mounted a certain way. Certain tires (like the OEM GY GSA's that came with mine) are directional or require a certain side "out".
But no, the wheels are all the same.
