I also have a very slight steering wheel "shake" about 40 / 45 MPH - balancing does not solve the problem, but I did observe that the Conti "marshmallow" tires are anything but round.Car is a '97 540iA with standard suspension and standard 16" wheels / 225 - 55/15 tires. I have 25K miles on them now and they are not all that worn. I probably will just scrap them and put on a set of either Firestone SZ50 or Yokohama AVS Sport. Suggest you jack up the car and take a very good look at runout - lateral and radial.
: recentely, i have noticed that there is vibration in the steering wheel at highway speeds of 70mph
: 2 days ago, i rotated the tires on the car...i moved the tire from the rear passenger side to the front passenger side, and did the same for the driver side...the rear tire which i moved to the front passenger side was a new tire which i had mounted 2 months ago (only this specific tire was damaged and replaced with my spare; the 3 other tires had 15,000 miles driven)
: so now, the driver side front tire is an old tire, while the passenger front is the newer tire with about 5000 miles on it
: i am wondering if the mix of new/old tires in the front of the car would be a potential cause of vibration, or must the tires be rebalanced, or must the car be realigned, or is there a more serious problem
