The lug bolt pattern will definitely work. Some drop-center tubeless tire type 16" rims will be too small in the center to fit over the brake drums. Be sure you have enough clearance to allow the wheel center to fit flat against the mounting surface where the lug bolts meet the wheel without hanging up on the brake drums.

Good to know - Thanks.
Is there a work-around, maybe an adapter plate that could be made? I presume one would need to have the wheel stand-of a bit from the brake drum?
