Harshness Solved
As mentioned before I was on quite the quest to work out the harshness of the 2018 E63. Took the following steps:
1. Changed the Pirelli P-Zeros to Michelin PS4 - $1200 - smoothed the ride somewhat, better sounding road noise although just as much
2. Reduced tire pressure from the max to the minimum - this helped a lot and I should have tried this with the Pirellis
3. Downgraded to 19” rims with Continental DWS06 All Seasons - $5200 - this finally solved the problem
The Conti’s are noticeably quieter, but most importantly almost all of the harshness is gone. This is for all poor quality pavement (which seems to be all we have in Texas) but most noticeable over expansion joints and driving over those little reflectors on the road.
For everyday driving the car drives smoothly and quietly (as it should in comfort mode). I will keep the 20” wheels and tires for track day, or when our group goes out for spirited drives.
There are some downsides. The Conti’s don’t track as straight as the Michelins, so you find yourself correcting more, and of course dry grip isn’t nearly as good. But the main downside is that the don’t look as good as the 20s.
Neverthess, for me this solved the problem and I’m finally very happy with the car.
For those interested, I purchased the stock 19” AMG rims from original-Räder.de. The cost was $2952 including shipping from German and they arrived 6 days after ordering. Excellent customer service and the wheels arrived in perfect condition. Tires from Tire Rack.

I recently swapped out my Michelin PS4 's to Michelin PS4 A/S. The difference in the ride quality and tracking feel was quite impressive. Since these are M+S tires the pressures are set lower front and rear (39 front, 36 rear) which improves the noise and impact vibration that I felt of the PS4. The noise level on smooth asphalt went down 10db and the pitch became lower as well. It's really a shame that MB doesn't offer these as a OEM option. The tread life if warranted for 45000 vs 30000 of the PS4.

I think the warranty is 1/2 if the fronts and rears are different sizes, at least that is what the Continentals are.
6 Years / 45,000 Miles Half mileage for rear if different size than front

Update: Apparently, side to side rotation is not recognized by Michelin as conforming. Hence, 1/2 mileage like Continental.

I recently swapped P-zero for the Michelin PS4 and have enjoyed a huge improvement in road noise and comfort. I thought about the AS but I run dedicated snows in the winter anyway so didn’t seem worth the trade-off.

Nice to hear your experience with this seller. Some folks were doubting their goods on eBay. They offer great prices for OEM wheels and tires.

It’s possible that you could use 19s and go up two series instead of one. Like 255/45/19 and some equivalent diameter 40 series rear. Have not tried but don’t see why it wouldn’t work.

thanks for sharing. i had the same idea and gladly someone have tried and is happy. i also feel the 19inch wheels fill the wheel well better than 20inch.
just put some 12mm spacers all round
