1st of all, Heartiest Congratulations and Felicitations on your purchase Dear brother!

May it serve you long; may it serve you Best! Amen.

YES. I have also observed the same phenomena in my newly installed tyres from Dunlop; LM 704 205/65/R16.
I do not know what is the science behind it? (because during driving, they are absolutely fine), but if you and me have observed it, then others will have definitely observed it too, and accordingly, it may be taken as normal.
