I comparing engraving date of ecopia againts other tyre like c.drive 2. Engraving date on ecopia sunken. But in c2 drive is rise up. So Im not mean the date itself as per say

And one tyre shop said there is machine that can change date on older tyre to a mew date.

But I have contact bridgestone that they said its ori, and its method of engraving date is like that, sunken.

Anyone who have ecopia on their ride can confirm, their date engraving also sunken?

Not too sure about that, may be my mate will be able to answer you. Summon r3apers

Anyway, I don't usually worry too much unless I see the production date area has an extra patch of rubber on top with relatively new engrave compare to the rest of the tyre wall, then I'll be worry or probably cutting samples for inspection
