The tires that I put on 1.5 years ago were Falken All season – pretty ****ty tires, but I decided to give it a try based on recommendation of the guy that claimed to be a “racer”.

But I just had another chance to make sure that there is no free lunch!

I got ~20K miles out of it. Those could probably go for another 5, but on one of them (RR) the metal court came out. ))
But I don’t think those were the reason for that noise.
There is only one thing could think of - I probably tolled you this sad story before, but… I took this car to the MB dealer for the alignment right after I had those tires replaced. The first time they were not able to make the steering wheel straight and car was pulling to the right, so I brought it back. Another guy performed the alignment for the second time, but told me that the car pulls a side because of the tires that grubbing the roat to much (or some BS like this, idiot)… to make long story short, I took my car to my friend’s garage, he has a lift, and right away figured out that front wheel bearings had too much play. I adjusted it and the pull has gone, the car became perfectly normal.
I think maybe they had something not tighten up enough when did the alignment, so it become even more loose and that noise came up? I am not sure what are the alignment point’s there, but I don’t have another theory at this time.
