Do I need worry about these holes in my tire?

I just noticed these two small holes in my front tire (28mm Conti GP4000S II):

I don't know whether these are a manufacturing defect in the tire, or were caused by some small object that then fell out from the tire. There doesn't appear to be anything inside the hole and it doesn't look like it's penetrated the tire completely.

It is anything to worry about?

Wondering if that is part of the mold process.

Those are tire wear indicators; when they disappear, they have worn down to the manufacturer suggested replacement point.

...those are tread wear indicators. When they disappear, it's time to replace your tyre.

Nothing to worry about, that's the wear indicator. When they're gone it's time to get a new tire.

Thanks for your replies - I had no idea that these indicators existed, so I've learned something new (and useful) today!
