Instability during overtaking?

[PoroFF]

Hi! I have a Merc W202 C220D Classic and it runs pretty good, except for one small thing: when I overtake bigger SUVs, trucks etc. at speeds exceeding 60mph quite often I get pushed aside by the air flow. A friend of mine has a petrol C220 and he drove me like hundred times and that never happened to his car. I find the clearance of my C-class a bit higher than his, probably this is the problem? I have stock suspension settings and the tyres are brand new Continental PremiumContact 195/65/R15 on stock rims. With the old winter tyres it was the same ... any suggesstions? I also attached an actual picture of the car (still with the winter tyres, but the height is the same).

Ride height will play a part of your problem. Has he got wider tyres than you?

well I only know that he has Merc alloys and they are 15 inches too .. I'm not quite sure about the tyres though ...

it also happens to me as well and i hace a w202 sport with 205/65 tyres and lowered suspension.

Type pressure is fine, I check it every once in a while, reffering to the values written in the manual.

Actually all suspension settings are stock, I've never changed anything but I really think to go and check it in the local MB service ... probably something went wrong.
