you're talking about a tired hare, right?
cycling is like baseball ~ it doesn't take much to make it interesting
No lugs, no care.
Just on the remote chance that anybody cares, the technical name for them is apparently "sprue nubs" or simply "sprue." I clipped them off once. It wasn't worth the effort, I barely noticed the weight difference.
Pulling them off with tweezers -----> screaming tires.

I let the pavement smooth it out for me.
I got a WTB Prowler like this, and it is COVERED in those darn things. I cut them off because riding on them felt very unstable. The tread was squirming everywhere and I even went down on the first turn. I used some side-cutters that would take off 3-4 at a time. Still took forever.
Most tires don't have so many nubs to matter and it would be a waste of time.
Made the mistake of reusing the razor I shaved my tires with.
Demented internet tail wagging imbicile.
Maybe biting them off would work????
Shave your legs, not your tires.
