3. Tires were rotated side-side to even out the wear
4. Tires were force balanced

There were no other anomalies uncovered. The car is a bit quieter now, noise at slow speed is gone, maybe a little less noise on the interstate, and the steering wheel center is now dead on. ($388 total bill)

The inner tread wear is the result of the aggressive negative camber (-1.54 degrees) which has been documented in other threads. Interestingly, my PS/4 AS tires had over 18000 miles on them and the tread depth is 6/23" which implies at least another 10,000 miles to be had before needing replacement. By comparison, I'm certain that I would have already consumed 2 sets of PS/4 tires. The fact that these cars only come with summer tires is a real crime. I took delivery of my wagon in Feb 2021 when the temps were hovering around 40 degrees. Michelin says not to use the PS/4 tires below 45 degrees and the traction on the tires was not good. Fortunately, it wasn't raining. I trashed the PS/4 tires within the next two weeks.

I don't feel any real reduction in highway noise/vibration after the force balancing, but it's hard to know without a control. The steering wheel center is dead on now and the car tracks straight (but it was OK before). I'm changing the tires out in the Spring so that should address any remaining residual noise.

What tire pressure do you put? Tire pressure also affects the tire noise to a certain extent.

First of all, I personally think the matte gray and black finishes are now well played out (and I have owned two matte black and one magno platinum matte G Wagons). Second, I think the chrome wheels are a terrible choice to go with the matte grey. Third, to charge this much more with no special performance gain to mark the end with truly one of a kind vehicle is a travesty. Very happy to have bought a Lunar Blue E63s Wagon in '21...you could not trade me for an FE with zero miles...
