I bought a CPO 2004 530i, prem and sport package over a year ago. From the get go the car had a vibration, mostly in the seats. After multiple trips to the dealer, Road Force balancing, 2 new oe 18" rims, I lived with it thinking that it was the run flats. Well my wife ran the car on the freeway with a flat and blew the inner side out of a tire and ruined a rim..... I was excited because I was not only going to get rid of the run flats but for the cost of one a new oe rim and 2 new Bridgestone run flats I could go to 20's on new rims. My buddy is in the business and we ordered up a set of Helo rims with the hub centric rings and Nitto tires. I had them Road force blanced. The rims and tires came in well with in the limits..... My car still frickin vibrates and I want to scream. The suspension has been checked by the dealer on multiple times and all is good. The vibration comes and goes but what is weird is that it seems that after some small bumps or road imperfections it seems to get worse. Control arms, all bushings, shocks and wheel bearings check out fine. I have read through a search on "vibrations" and see that there are some cars out there with similar symptoms but have not read any cures. Any help would be greatly appreciated. One positive note..... the 20's ride way better than the 18" run flats.

I have the exact same problem as you. Car has 59K on it, same year with sport and premium, OEM rims, Goodyear F1 GSD3 tires (much nicer ride than the runflats). I initially thought it was the balancing, but after several balancings, it most definitely is not that. I get the 'vibration' you are talking about at around the 65-72 MPH area. Usually is worse when the car is first started in the morning. I had the 'vibration' on both the Bridgestone runflats it came with and the Goodyears as well. It's been going on for probably for 18 months (since it came out of warranty!). It seems like after the car 'warms up' after about a 1/2 hour or so, the vibration is less around those speeds. And it is a strange problem because some days it vibrates (on the same roads) and some days it doesn't. When it does vibrate I can speed up and then let off the gas and coast to the speed it was vibrating at and the vibration disappears. So that leads me to believe it is not the balancing but possibly some sort of engine shudder, transmission issue, or something else. I'd be curious to know if your vibration goes away after taking your foot off the gas.

You did a great job of explaining the problem.... yes we have the same year car, same options and the same problems. I have been through 2 new OE wheels, countless Hunter Road Force balancing at the dealer and other places, new wheels and three stes of new tires trying to find the problem. I am 100% convinced that the problem is with the chasis. I can tell you that I will NEVER buy another BMW do to their lack of ability to find the problem. I'll play more with the gas pedal and let you know what happens.
