W205 Ride Quality

[petrolhead123]

Took delivery of a new W205 C180 9G-Tronic. 17 inch rims, standard steel suspension. Everything about the car is perfect except for the suspension. Didn't really feel the firmness of the ride during the test drive but only after driving for a few weeks. I wouldn't say that the suspension is very terrible, but definitely not what I would expect from a Mercedes Benz. The car is particularly uncomfortable over larger potholes.  Surprisingly compared to the 3 Series this version of the C Class feels less compliant overall. Anyone feels the same way too? Thinking of changing the run flat tires to normal tires but would that void the warranty from C&C?

1. Are you on avantgarde and RFTs? Feel RFTs are somehow rougher and less comfortable.

2. I also feel you as atleast for me, the car does not do well at low gears and low speed. Kinda jerky.

Change of tyres no issue w warranty.

Am on the Avantgarde Trim and RFTs. Tires seem to be losing pressure gradually too. Increasing tire pressure seem to improve ride quality, making it less wobbly and reducing impact harshness. This is contrary to the expected effect. Been reading other forums too and it seems like there are others who also feel that increasing pressure on RFTs improves ride quality.

I have the same feeling too. I’m on adaptive suspension and the complaintness of the suspension is actually quite poor
