It is very bad sign, should not happen, in new tires.Have almost done 4000 miles on my S20s and they're still in good condition. I'm not pushing it hard and not doing wheelies so maybe that's the reason. The thread is still deep but I've noticed that the tyre is starting to look "cracked" in places. Not having owned bikes for long not sure if that counts as wear
Can take a pic tomorrow if needed.
