I worked in truck/heavy equipment tire shops back in the early 70's. I've had split rim tires blow up on me, while they were in a cage and I was inflating them. If you weren't using a cage and it blew up, you ran a serious risk of not living to tell about it. They are very dangerous and there's good reason why they're called widow makers. I would absolutely look for another rim/tire combination to replace them.
My guess is the one's that blew up were the Dayton type split wheels. The split rings were actually pretty safe, I used them for years on my log trucks, mostly one piece but some two piece lock rings.
The wheels on that trailer are rare for the era, in the fact they are both hub centric and lug centric. It is hard to find 15"-16" tires with a 4k capacity to match the 16k of the trailer. It is quite possible the owner doesn't need that much tho.
It might be easier and cheaper to replace the axles with a modern set v/s custom built wheels.
