Tighten it down and I'd bet it will be 30mm

Might be 30mm. but another possibility is they're actually 1-1/4" hubs...
Easy way to confirm things is accurately measuring the keyway with a digital Caliper:
1-1/4"-hubs have a 1/4"-wide keyway.
30mm-hubs come in 2 different keyway variety's: they will either have a 6mm-wide, or 8mm-wide keyway.
If you don't have a digital Caliper, you could start by simply seeing if a 1/4" key snugly fits into the keyway or not. 1/4" key will be too wide for 6mm. and not wide enough for 8mm.

This. That's a clamp style hub. Tighten that bolt down and it *should* squeeze it shut and clamp in place.
That's why there's a split down the side.

That's not going to work then. The key is what transmits the torque. Doesn't really matter how much you tighten this type of fitting, you won't get sufficient hold to transmit the drive torque.

It would still be nice to know the outcome, for future reference and all.
