I have a 99 S320 where the front-end vibrates in the morning for 10 mintues. I guess until the tires warm up. After that, there is no mre vibration. What could be causing this? Is it the tires or rim? I have the factory 16 inch MB rims, and the tires are Michelin MXV4 PLUS 225 X 60 X 16.

 

I'm having the same problem with my S500.

Front end vibration, very slight, at above 65mph getting progressively worse as you head towards the 110 mark.

I'm looking into getting the tires replaced, but I need to check the tire pressure, and the propellor shaft.

My rims may have been destroyed also from the refurbishment process I recently undertook. 2 separate wheel balances haven't solved the problem.
