In the flesh, they looked more like center punch dimples - not drilled. And every such balancing hole that I've ever seen either had a very shallow point or none at all. Were these balancing points, why would they have drilled three close together and then another three nearby. And more elsewhere? A novice machinist or apprentice robot?Those look like holes drilled in heavy spots to balance the wheel.

Shiftwork.....Yeah... right... Rockwell Hardness Test... I say, PLTTtttttt.....
Then explain why they only happen at night.

I'm not the orig owner. But there are no scratches or signs of damage to the rim.Were you the original owner? I wonder if the rim was damaged and these are signs left from someone trying to true or straighten the rim?
Never come across them before.
Maybe that little 3 point laser light that the Predator creature used
If so, must have been Neptune's trident - and ole Nep kept missing and trying again.I wonder if something punctured the tire and damaged the rim?
I like this. must have been a newbie testing the rim - lots of tests - I pictured 6, in two sets of 3, and there is at least one more set of 3, maybe more (I was not counting or paying attention).Rockwell/hardness test to measure hardness of wheel. Hence the 3 spots...not perfectly symetrical each time. Take 3 measurements move to different part of the wheel. Reason why not many of us have seen it before. Probably the start/beginning/end of the manufacturing lot.
