A small notch ... Problem?

It's not even a month since I installed new tires, when I happened to see this on the back tire

And from above. You can see a slight bulge.

So, the tire is not cut and the hole is not widening for now (I drove about 300 km, to see if anything changes), do I have to worry?
Is there something like some light patch (some glue maybe), that would prevent any possible further expansion of the notch?
Tires are Michelin PRO4 Service Course V2, if that's matter.

How does it look from inside? I had something similar on Challenge tyre and threw it away, not worth trying luck..

I didn't take off the tire. I'll see in a few weeks when I'm probably going to change tubes. If nothing else happens before :)

It's fine, just ride them. I really doubt anything catastrophic will happen....At most inspect it before every ride.

I will probably just swap front and rear tire then. Just to little ease the pressure.

I would keep it in the back. If it does blowout, a rear flat is usually more recoverable (less chance of crashing) than a front flat.

If it were my tire I would keep riding it, but In the back.

You can sleeve that area with a section from an old tube if you're thinking of riding it.

I will see first how it looks from inside. If there is nothing to see I will ride it like this.

There wont be any signs inside -it would have exploded by now. Still, put a patch inside using material from a flexible cotton tire or thick camera and shoe/tubular glue.

Wouldn't patch from inside make bulge more prominent?

Anyway, I never patch the tire, don't have properly strong glue (don't understand what "thick camera" actually means :) ) ... I think I will stay away from that. More so because I noticed that tire inside is very, very non adhesive. It feels different that other tires I had.
If it holds up, ok, if affected part start to spread I will change tire.

An inside patch will definitely not make it any worse. Thick camera, I meant thick tube, as in a 100g butyl one, or cut from the side of an old tire. Shoe glue should be available in many stores. Use sandpaper to roughen the surface of both patch and tire, spread a thin layer in both, wait 10 minutes, press together for a couple minutes. It is the old way tubes used to be repaired. Don't use superglue, it dries too hard.

I'd replace it. No way I'd trust that tyre.

It's a slight scratch in the top layer of the rubber.
It's not load bearing, you can see more rubber underneath. It's not tread.

I'd ride that with absolutely no concern.

Just have a look when you clean the bike. If it gets worse. Let the tyre down and put a bit of glue in the scratch and let it dry. Then ride some more.
