Slight vibration
Hi everyone ,
Recently I have been experiencing very slight vibration on highway when reaching 110-120 km/hr. Its like the feeling of a very slight air-turbulance in plane , stable but just discomfort feeling while on highway. The vibration can be felt coming from the wheels, tires but not the steering wheel. Before, my S class was very smooth on highways with no problems. I did tiresand steering wheel balancong and the problem stayed . The mechanic told me that my winter tires can serve me for one season not more , which means they are in normal condition not much left.The car level is the same i have no errors on my dashboard even i checked it today. Airmatic works fine with no errors
1. Can it be an air srut failure?
2. Tires ?
3. Some suspension parts which needs to be changed ?
Any suggestions?

if you dont feel it in the steering it is usually rear tires, tranny bushing or driveshaft.
my bet is your rear tires need to be rebalanced- 120km vibration is very typical for out of wack tires
