14T Baler Rim Question

But today I went about putting the best of the spindles and rims on my working baler and found this:

1. The pick-up side of the balers, the spindles on the '58 are the same diameter as the fly-wheel side, though both are only 4 bolt holes. Is this original? I thought I'd put the heavier spindles on the working baler.

2. The rims for the '58 baler, both sides, are about 1/2" wider than the '62. The rims off the '59 have some numbers factory painted on them. The pick-up side has JD-1384 and the fly-wheel side has JD-689-F, thought the 9-F are hardly readable so those may be wrong. The '62 baler's rims have no markings on them and the pick-up side had what appeared to be the original tire, a Goodrich 5.00 x 15. BTW, of the two sets of rims, the '62 is in the best shape. The '58 rims look like they have been run flat for a few years! Anyone else found different rim sizes on 14T balers?

3. Anyone retrofitted their tubed tires with tubless?

Thanks in advance,
Bill

In farm stuff I prefer to put tubes in tubeless tires. They aren't going to flex enough to heat, and I think they hold air better. When the farm has dozens of tires, airing the leaky tubeless tires gets to be annoying. And often the older rims weren't made to be air tight at the weld, so they do leak excessively without a tube.
