I have no clue..but I'll give my idea what I think they're for.
I venture to say that it's a QC check.
The stripes are laid with the tire spinning on some machine.
One stripe from one side, one stripe from the other.
The tire is rejected if one of the stripes comes out of the groove.
Like I said, no clue.
Just seems like a logical thought, to me.

The stripes are there strictly for identification. It makes it easier to prevent mixups within the factory if you can quickly identify the tires.
They are painted on the surface of the tread when the tread is extruded. If the stripes are on the tread surface, then they will only last a hundred miles. If the stripes are in the grooves (and it looks like the white one is), it will pretty much be there for the life of the tire.
Also SOME tire manufacturers use the dots to denote low point of runout and also high point of imbalance. Out of round, weight imbalance- both require weight to offset.
