125 Lug nuts?
 

Has anyone ever installed 7/16-20 (I think) fine thread bolts through the back of their hubs, then used lug nuts? If so, how long were your bolts? Did you put blue Loctite on them?

I split my 125 to replace the trunnion springs and putting the rear wheels back on was interesting. I’m going to add ballast before I plow my garden for the first time and I feel like lug studs would be easier to deal with after my tires are loaded.

There is a trick to using bolts rather than studs and nuts and I find it easier. My tires are loaded and I'll be putting them back on after splitting, same as you.

Start with the hub just a bit low and put one bolt in at 3 o-clock. Now simply raise the jack until you can put the rest in. Way easier than trying to get the wheel and five studs lined up while pushing and lifting the tire.

I bought a valve to fill my tires from Amazon and used RV anti freeze. Just used gravity fill and it worked great. I found a site (googled it) that had a chart for the volume of my tire, pre measured that amount into a five gallon bucket, set the bucket on a ladder and let it drain empty. Might have taken an hour per tire?

EDIT: I just remembered that I cheated a bit because I have a five gallon pail with a spigot at the bottom for running anti freeze into my inboard boat engine. But siphoning still works, just have to fill the hose or suck on it like the old days of getting gas from dad's car to run your toys.

Ahhh gotcha. My tractor was on jack stands when I put tires back on.

Simply cut the head off of a bolt or two and use them as a centering pin to mount your tire and replace them as you get the others snugged up.

I replaced the bolts with studs, very easy conversion. Here's the place I got them and the part numbers.
