Re: how can this be (tire balancing)
i honestly think their machine is off, or the tech entered the wrong specs. our machine is very nice bu at one point caused a shimmy in every customers car. we went through and did the calibration on it and has been perfect ever since. good luck, hope you get it fixed!

Re: how can this be (tire balancing)
Now I'm not so sure the balance is off. Heretofor I had only driven it at the listed speeds on 199. Today I took the car to work (50 miles of I-64) and while it felt like it had a tire balance issue on the less-than-smooth parts of the road, on the smooth parts it seemed fine. The weird thing is on smooth asphalt roads the tires seem smoother and quieter than the Michelin Pilot Sport A/S that were on there, but on rough or concrete roads they are louder and harsher. I guess that explains why I was having to pump up the Michelins to keep the sidewalls from tucking.

The Toyo T1Rs are smoother and quieter on smooth roads than the Michelin Pilot Sport A/S I had before were.
At the same time, the Toyo T1R are rougher and louder on rough roads than the Michelin Pilot Sport A/S I had before were.

Re: how can this be (tire balancing)
check the date on your tires to make sure they are new
use a marker or chalk to mark the tire and rim and go drive it and see if the tire moves on the rim.
sounds like uh ave a nice car, i used to work at mb in tysons..
i worked on newer chassis w211, etc - not sure if ur model has 'thrust arms' or adjustable wheel bearings - sometimes those can create vibrations if misadjusted...im assuming your alignment is good rite?

I'll have to look through my service manuals. I don't know too much about suspension, but it's a double-wishbone in the front. IIRC the wheel bearings are not adjustable - you just replace the rears when they finally wear out and you repack the fronts every time you change the brake rotors.
