It has a split rim that would require some sort of adapter or custom split rim (as mentioned above).

You don't want to know how many of those 330 wore down between 2005 and 2007. Fortunately, the tire is available separately. (They were our center wheels in a 6WD.)

We did have a custom adapter made in at least one of those years; ShaneP designed it, IIRC.
