I had a similar issue. Turned out to be bent rims. there rims are really soft and the rubber over them is thin, making them prone to bends. Check the wheels first (even if they are new) and then others.

I had the same problem on my old car, the issue for me was bent rims.

You have new rims so my question is if they are centered to the hub by the center hole or by the lug bolts.


I bought a set of after market rims and a set of new tires. First they were mounted using the original hub bolts. Resulted vibration problems just like you explain.


Then conical (tapered) hub bolts were used but this helped only a little bit.


What fixed the problem was to use centering rings. Original MB rims center to the hub using the center hole of the rim but on my after market rims the center hole was too big. Center hole in most after market rims is probably made big enough to fit most cars to be able to sell them to most customers so it probably is not correct size for many cars.


The tire shop installed centering rigs (filler rings) to make the center hole of the rim tight fit with the shoulder ring on the hub and this fixed the problem 100%.


So the question is how your rims are centered to the hub?


If they are centered using the center hole then I cannot tell what to do if everything you mention was done correctly but if centering of the rims was done by the hub bolts I recommend getting the filler rings installed.
