Here is some useful information for rims/tires dimensions/spec's etc.
I don't know if this has been posted here,
and I don't know where it is should be posted,
so I'll let a Mod move it to the proper place.
HTH's.

I put my hub motor nuts up to around 25 ft-lbs, no loctite, I used to do them by hand. I would bet that would be around 20-22 ft-lbs, just a guess. I think the charts say 40 ft-lbs or more?, That's for a full 12mm axle, and we're missing almost 40% of the thread with the two edges of the axle missing,
