I saw a "B" series (cut-away Van "Nose") Dodge chassis under a Class C out in Oregon and it had the 16" wheels. I wanted to catch the owner and ask what he'd used, but I didn't connect. Suffice, it CAN be done.
You have what's known as "coined" or "keyed" wheels. Every other hole is either recessed or raised, right? And there's a pin in each rear hub that lines up with a small slotted hole in each rim...? That's to make sure the rear outer "coins" line up recesses and raises with the inner.
Unless somebody here just jumps out with the interchange info:
gOOgle "dodge coined wheels" and you'll see pages of hits, with the answer buried someplace within, I'm sure. Just beware that Pickups may have different wheel specs than cutaways/cube vans, and may have switched away from coined in different years.
A salvage yard may be able to help if they'll take the time to look up the interchange. There used to be a book or service "Hollander Interchange" and maybe there's something on line.
You have to match
Centering: Lug, Piloted or Coined
Number of Lugs
Lug Circle
Dual Wheel Offset
Rim Width
... and probably more
That said:
Firestone Transforce is a very good tire. gOOgle 8.75R16.5LT and you'll get lots of hits. Transforce seems to be one of the few (if not only) name brand among acres of off brands and cheapies.
A member here, capriracer, has a site called
Barry's Tire Tech and it has the 16.5 page I linked. Helps determine a good 16" tire to swap into.
