Does anyone else have difficulties driving in side wind (cross winds)? Or is it just my car?

I think my X4 is quite dangerous driving over 60 mph (96 km/h) in high winds.
Last week I tested driving at 90 mph (145 km/h)and the X4 was all over the road. Scary
Have not experienced that with a X5 I also drove at high speed and high wind.

Same thing happened when I drove on a highway with severe ruts (wheel tracks) and no cross winds. People must have thought I was drunk. Could not keep the car in a straight line.

I haven´t got DHP and are driving wit non run flats.

I din't have this problem with my X4.

Do you speak about a very big lateral wind ?

Has really no one experienced this??
Is it just my car?

Have no dhp, 18" rft stable as hell. What tire pressure are you running?

[Jypsie]

No problems for me: 18'' RFT's stock and pressure set as per the manual. I do have EDC but not sure what dhp is.....

EDC and DHP is the same thing i think. Electronic damper control & Dynamic handling package.
Have tested 2,3 / 2,6 / 3,1 pressure with almost the same result. 3,1 is somewhat better.

X4guy and Jypsie - you´re both driving with 18" and seems to have no problem.
How wide are you driving?
I´m driving with 245 up front and 285 on the rear.
So perhaps the X4 doesn´t like to wide tires.

The X5 i recently drove had 315-tires in the rear and was "solid as a rock"

Have just scanned the internet and there are some notes about the X3 having x-wind problems. I also read in one test that the X4 has inherited the wind-sensitivity from the X3.
To short wheelbase? (My thought)

I had problems with sidewindsensitivity before lowering. I drove 400km (250miles)yesterday, partly in windy conditions. I was surprised about improvement with lowering. It is difficult to say how much improvement - but there IS obviously an improvement.
80 % of the irregularities (bad road) was no problem - but 20% was unpleasant.
I don`t regret lowering.
I have not checked/had wheelalignment after lowering.

20" 310:s,RFT, EDC in Sport.

I - and my X4 - likes the wide tires

I have 368M's 245 front and back. I am considering the 310's a summer wheels though.....

Just took my X4 (2015 35i, M-sport) on my first road trip which included about 100 miles on the interstate. I didn't experience any issues with crosswinds or staying in my lane. Riding on the 19" m-sport wheels with the RFTs.

One issue I did experience however was how sneaky fast the thing is. I frequently found myself doing over 80 even though it didn't feel like I was going especially fast.

Ok, more info: Back from a 1500km trip through Germany (nice highways , Never had a problem with side winds.....

Car was a bit "sensitive" when doing 210km/h though, but that was to be expected and then the side winds were pretty strong.
