Is this the beginning of a tire bubble?
Also since yesterday the allignment is completely off. When the steering wheel is dead center, car goes to the right. To go straight the wheel has to be to the left about 15 degrees.


PMB, those OEM tires are the pits. Mine came with the crappy Contis (I see you're on the Italian version.)
The roads here in LA are equally as bad (I think pretty much in the whole USA as the infrastructure is falling apart everywhere.)
I recommend changing all 4 out to a better tire. I immediately switched to Michelin PS2 (I was able to sell the OEMs for a fair price since they had only 30 miles on them.) A tire with a stiffer and better made sidewall helps a lot (and in handling, too, that's for certain.)
I like my 16" wheels on my C-Class! I won't be driving the E to work tomorrow, don't want to be on the highway with a potential blow out waiting to happen.
