#6 of 10 BMW 5-series Handling Problems by palb

In august 2008 I bought a new BMW 520D and was very disappointed about the stability of the car. It was very sensible to the quality of the road covering. I did complain, the dealer tried the car, but found it to be all right. I suspected their factory delivered “run on flat tires” to be the problem, and insisted on having the tires changed. I got it my way, and they put on Hakka Z. Now the car is running absolutely perfect! (Afterwards the dealer admitted they had big problems with their run on flat tires).

Not sure that this is the issue here, but EVERYONE buying ANY new car of any make should check their tire pressure immediately after buying (next morning when cold is best). It is a common complaint to find tires grossly over-inflated and that will always contribute to "squirrely" handling.

I have the same problem, dealer doesn't know what to do. Did you get yours fixed?? Was it the tires?? I have 700 miles on a 2010 528i.

At highway speed the car seems to want to go right and left. They checked alignment and added air to 39 in all tires, still have the same problem, is it the run flat tires? Tire pressure?? Anyone know of a fix?? I have 700 miles. At low speeds it feels ok. I have sport pkg and run flats. I also have active steering which is supposed to make it drive better at high speed.

This is due to longitudinal grooves on the highway surface. Hwy85 in SJ as of a couple of years ago (and may others) have those as a noise reduction feature. (Tire noise on highways is due to air in the contact patch not being able to escape and "pop". Grooves help avoid "popping"). This is tire-specific--softer sidewalls/less aggressive tread seems to alleviate some of the effects. See http://www.tirerack.com/tires/tiretech/techpage.jsp?techid=47 for more info.
