So you know the tire is new.

you must have thought really hard on this one.

from the holes (mold vents) used in molding the tire....

My best guess is, that it avoids vacuum (between the mold and tyre) and aids quick mold release...

p.s. I work for a rubber molding company...

 

They are called nipples thank you.

The fingers are actually from where the rubber goes in and air goes out. If they weren't there, there'd be no way to ever mold the tire. It's kind of like trying to fill a bottle with the cap on.

Not true IMO, Tyres are not always injection molded ...

As far as i have seen, rubber is placed in the mold, the mold is closed and pressure and heat are applied...

You need a place for the extra rubber to go, since it's almost impossible to use EXACTLY the right amount. Safer to use a little extra, and give it an exit.

actually tires have those yellow and blue lines over em to see if they're new...

 

My guess is that they are from the mold.
