Sorry to bring back an old thread, but did anyone here ever find out who makes a 15 inch rim with the large 6 lug pattern? I have a dually axle from a motorhome that I am thinking of putting on my '88 4x2, and I might eventually want bigger tires.

If you have not done the SAS yet, I found that some old Internationals and possibly some Fords and Dodges in the 60s had that same pattern. All the rims are split tube-style rims so they will not work for me, but the front axles might work for a SAS.
