Suspension feels awful!

Since the temps in NYC has dipped below the 40 degree mark, my car has felt awful.
Every small bump in the road can be felt. It feels like there is no compliance in the suspension. On smooth roads it's fine other than being a bit squirmy on hard corning, but on less than stellar pavements, I feel like I'm driving a box truck.

I assume the change in ride comfort is due the colder weather affecting my General G-MAX AS-03 tires. These all seasons were pretty comfortable prior to it getting really cold.

Is it worth getting my suspension checked or is it truly a tire issue?

That's how I feel about my 06 530i. I'm new to BMW, and the car has 100K+ miles so I was thinking maybe suspension parts are worn. I just got new tires two months ago and I felt a noticeable difference, but, the suspension still feels like it hits too hard on anything. New shocks are in order, not sure?

I have a 2010 XiT and had the exact same issue - maybe even a bit worse as it would have a loud "thud" when going over large bumps in the cold - such a a speed bump - even crawling 1-3 mph. I did put on the KW Coilovers this fall and thus far have not had the issue. My sense is the stock shocks/ struts simply do not like the cold weather.

Sounds like what you are describing are the sway bushings being a problem. Do a search on the forum. They get worn and in the cold they produce a sort of crunching noise as you go over bumps in cold weather. I've noticed this the last couple of years with my 06. As I understand it this isn't a critical issue and if you can deal with it you don't necessarily need to do anything about it. But I'll let the experts chime in.

It can be your shocks if you are over 70K miles. But generally sport suspension on E60 is pretty rough - cars with standard suspension are much more compliant.

I have a set of brand new standard OEM struts (shock + spring complete assembly) for E60 if anyone interested.
