What's Vanilla Ice doing at a Blockbuster?

Sounds like threading is an easy first option, and you have other options if that doesn't work for some reason. Let me know how it works, and good luck.

Edit: On second thought, it should be enough to add threads as long as the axle is thick enough per spec, I'd just suggest doing a manual pull check once it's done to make sure you're not going to be three-wheeling it home.

If they're using speed nuts to hold wheels on, I'm loathe to assume they're using the correct axle materials.

If I'm understanding correctly, those are called speed nuts, and shouldn't be used for anything taking forces as high as an exterior wheel would have. It does depends on if the wheel has anything else holding it on, though.

I agree with the caps. They tap on and hold pretty well, though you'll need to make sure they're tight enough to hold the wheel without letting it wobble.

If you do want to make your own threads, you need to make sure the axle material is strong enough to handle it, otherwise you'll lose the wheel and need to replace the axle (if/when the threads break).

You could also look into how the axles are held on, and if you can replace them with a threaded rod, though this is much less likely possible unless you have decent welding or riveting skill.

Edit: autocorrect sucks

Is it Anna or Elsa?

Well, 3cm is just over an inch, so it's more like a 5'9 guy vs a 5'8 guy

Irish Catholics vs Irish Protestants, there's bad blood between them
