Profile resolution on new tyres?

Today I noticed profile resolutions on my winter tires, am absolutely speechless, since the tires are not mounted for 2 weeks and are brand new It is Yokohama W.drive V903, all 4 tires DOT 1615, Made in Philippines. Dangerous distance so far about 300km, of which 180 AB, rest city. No high speeds, as those were mounted on our Clio. Air pressure is minimal above factory specification, VA 2,4, HA 2,2 bar. Notable also, that it seems to concern only the rear axle. nks quite strong, back to the right less. At first glance everything is in order, for safety reasons but also from the tires times pictures. It also seems to concern only the tire outside. But just look for yourself. Someone has seen something like this before?
