I have Mercedes. E class 08 reg my car shake when drive high speeds and when going up hills
If you're high speeds are like my high speeds. You need to have a high speed balance done on the tires with a road pressure test done at the same time. But remember in the states the high speed balance is about to 60 -70 MPH at the most not like when in Germany my top end was when the speedometer quit working. can't do that here the machines are only set to about what the state highway commission sets. But I'd really would find a dealership or tire shop that has a brand new tire balance machine it's worth you wild to do so.
