Sorry to necro this thread a bit, but how much of an improvement did you think the 19s were? I'm in the market for an E63 sedan - have always really wanted one and love the W213 (esp the Wagon but they're in the stratosphere now pricing wise). That said, I already have a weekend / canyon car and while I don't mind a firm ride, want to avoid a jarring one for an E63 that will be me and my wife's daily. Roads are actually decent in Marin county, but the car would be driven into SF and south of there where the roads are a lot worse

So I think the PS4S in 19 isn’t even worth trying. That tire is so stiff on this car. I went back to stock wheels with spacers and Continental all seasons and it is WAY better. You definitely loose some turn in and precision but the ride is much better and I think the launch is better as well. Also the continental are way better in the rain.

Thanks, good to know! I'd be planning to run all seasons on it anyhow given my wife will be driving it as well year round

Well, I'm sorry to say that in the end I just couldn't keep the car. 75% of the reason was the ride quality, 20% road noise (even with the Acoustic Comfort Package), and 5% other annoyances like no more live maps after 3 years. The 19s with the all season Continentals were a significant improvement, but it just took it from absolutely horrible down to just awful. Part of the problem is that we live out in the country where the roads aren't great. I think if we lived in Germany where almost all the roads are excellent, it would be tolerable.

It's a real shame, because other than that I really liked the car. All that said, I still have the set of 19s with the OEM AMG rims and the Continental DWS06 tires with about 2500 miles on them, if anyone wants them.

I live in Chicago with terrible roads and came from a stiff lowered W205 C63s, I never thought the ride was that bad in the stock W213 or now lowered E63s... You old people should just buy S classes instead of high performance AMGs.

I did exactly the same: Conti DWS Plus All-Seasons. Drove in snow and Ice in the local mountains with no issues whatsoever. And the ride is waaay better than the Michelins that came on the car. Highly recommended!

My 2020 wagon came with 20" Pirelli Pzeros. I hated how they rode. Harsh, lots of scrubbing when steering at low speeds, tons of road noise. They really made me not enjoy driving my otherwise fantastic car. A couple months ago I put on 19" Conti DWS06 winter tires and the difference is night and day. None of the gripes I had previously still apply. Not sure if the probelms were inherent to 20", or just to the Pzeros, but I won't be putting those tires back on under any circumstances.

That said, I wouldn't say the ride is plush or anywhere approaching it. It's fine, but frankly our Honda Accord (with 18-inch wheels) is better on rough roads.

A few random thoughts on comfort.

My 2021 wagon is extremely comfortable. Suspension on these is a little clunky no matter what. I find Sport (one light on suspension button whatever that's called) works best for my comfort. More damped, a bit firmer but less clunky.
Michelins always seem better than alternatives in my experience. I love the Pilots. And the ride is even more comfortable with my winter Alpins. I'm no fan of all-season tires unless we're talking minivans.
Make sure your tire pressures are not too high. Do not follow silly recommendation on driver's door jamb rather go with lowest suggested on gas filler door. Never use run-flat tires.

Completely agree with the above! I run 41 front, 36 rear on Conti DWS06 Plus all-seasons. Ride is 90% better.....

Before I went to the 19s with Continental I tried Michelin PS4s on the 20" wheels. The Michelins were somewhat better than the PZero's, but the real change came with the 19s and the all seasons. Perhaps there is a 20" all season option that may also work, but I couldn't find anything at the time.

I hesitate to respond to the old people remark other than to say that there is probably some truth to it. This would have bothered me less 30 years ago. But the point of getting the E63 instead of the GT is to get more balance. I think MB fixed this largely for the 2021, but the suspension in the previous versions were a fail in my view. MB itself realizes this as they largely fixed it for 2021 and offered fix for most markets (except the US and Canada) for the older models.

As to the C63, oddly enough it doesn't seem as bad to me as the E63. I only had limited exposure to it at a recent AMG Driving Academy event, but in driving both a 2020 C63 and 2020 E63 back to back, the C63 seemed more livable.

🤣

I'm closing in quickly on 70 and have a 2021 E63s sedan. It is quite comfortable to my wife and I. We have taken it on three fairly long trips and found comfort mode pretty smooth. With the active seats and massage we can stay in it for extended periods without back or leg discomfort. I've never been in a previous model so I can't offer a comparison to those.

One of the side effects of using the Sport suspension setting is that the car is lowered by .6". That would not only yield less travel, but also would increase the front tire wear due to the increased camber. I'm not sure if I understand the "clunky" comment, but the suspension seems to be well controlled. Could you explain further?

The 2019 C63 was the first to get a revised suspension as part of the FL. Just like the E63 did for 2021. Similar changes in both cars. Newer generation dampers, bushings and dynamic engine mount changes. Prior to the revisions, AMG suspensions arguably had a bit of a harsh edge, but I think people need to realize what they are buying. If you want comfort, don't buy an AMG. That's what the regular Mercedes-Benz models are for.

Mercedes just needs to can all the people in the Sport Suspension department. There are other ways to generate dynamic performance other than super stiff dampers.

Weirdly enough, I had recently purchased my used 2018 and the ride was ROUGH. it had the cross spoke 20's with Michelin PS4S on them. I was paranoid about going 21's with a lower profile, but I went ahead anyways. I am now running 21 inch Michelin PS4S and the ride is night and day better! Maybe its the new tires? Who knows. I don't know how old the other tires were, but they can't be more than a few years old since the factory tires were not the Michelin.

Most likely tire pressure. A lot of folks seem to be running the wrong tire pressures. What's on the door sticker in North America is way too high on these cars. That's for a fully loaded car and driving above 155 mph on the German Autobahn for extended periods. If I run those pressures in my C63S for normal driving, the ride is brutal. For normal driving and <= 155 mph the recommended tire pressure is much lower and listed inside of the fuel door. Running the correct tire pressure is night and day.

Completely agree there. My tire installer used the door jamb figures when they installed my new Contis, and I swear it drove like I was on grease! I dropped them back down to the lower settings from the fuel door (41F, 36R IIRC), and it made all the difference.

Yes, 100% on correct tire pressures. It's surprising how few people realize this, including MB dealers. I find it very irritating that every time I take the car in for service I get it back with all tires set to stupid-high pressures, even after telling them to not touch them or read the fuel-door...duh. I wonder how many sales they've lost by simply screwing this up on a systematic basis and sending people bouncing down the road?? Whoops.

What I don't understand is: why would MB have different tire pressure specs in two different places on the car?

So I assume the "fix" provided to non-US/Canada markets was performed as a firmware update, through the OBD-II port, with no changes to hardware, yes? I wonder if those companies that offer things like lowering modules and the multi-beam LED headlight upgrades could somehow write the program to offer this "suspension update" as well...seems they could get hold of an updated car and copy the program...just a thought...

I believe it's related to regulations. The pressures in the door jamb are for max load/speed rating and MB is simply providing the alternative pressures for other load/speed ratings elsewhere on the car. Much better than having to dig through a manual.

Blame your fellow citizens. In the ROW, the door sticker has all the same information as we have inside of the fuel door, but the average American apparently doesn't have the brain capacity to process and understand this information. The door sticker was changed to the useless information it is now in response to the Firestone incident in the 90s that was traced back to owners not running the correct tire pressures, and as a consequence tires overheated and the tread separated, causing accidents and even deaths. So now car manufacturers are required to put the highest recommended tire pressure on the door sticker as it is the safest, but those who don't know any better will have to put up with a less comfortable ride.

As for the suspension, I thought I'd share my experience I just had. I just picked my '19 C63S coupe up from service. They had given me a '21 C300 coupe loaner, which comes standard with fixed sports suspension. I was amazed by just how much more comfortable my C63 rides compared to a regular C300. The AMG suspension is more directly connected to the chassis, and may have a slightly stiffer spring rate, so initial impacts from bumps are felt and heard more, but the damping is just so much better in the C63 as it was in this C300. The C300 bounces and bobbles around. I was constantly hopping in my seat where as the damping in the C63 keeps the body calm and leveled. To me that's a much more comfortable ride. I typically have the suspension in Sport on the highway and compared to that C300, the C63 just wafts along. Quickly settling and keeping the body from moving constantly over bumps in the road. It's just kinda amazing what active and adaptive damping is capable of these days. On top of that, the AMG Performance Seats are just so much nicer and more comfortable than the sports seats in the C300. The performance seats are another thing some owners complain about, and I can't relate to it as I find them super comfortable even on an up to 12 hour drive. Obviously no point getting into the powertrain. Night and day, but also the 9-MCT is so much better than the 9G torque converter box in the regular MB models. Just a different level of transmission.

Harris, by clunky, I'm describing how the car often feels over uneven potholes, especially around bends in the road. Car kinda 'skips' over the potholes and larger bumps. Usually feel the 'clunk' in mainly the rear wheels. The chassis could most certainly be better dialed-in. You know the horrible roads here in the Northeast... they're a great proving ground. I'd have to let you feel how the M5 CS or GT3 deals with the very same roads for you to truly appreciate what I mean. MB could certainly learn a thing or two from both Porsche and BMW about suspension tuning. Don't get me wrong, it's very good but I'm just comparing against cars with better suspension. I know this is likely just in my head, but I swear my Graphite wagon felt better with the ceramic brakes. I'm nitpicking here, the car rides great overall. It's just you can most certainly feel the weight of this car on bad roads whereas the other do a better job maintain total composure. I suspect the heavy cast wheels don't help much in this regard either.

As far as why there's two different air pressure recommendations... The one in the door jamb is written by their lawyers and the one in the fuel filler door's written by their engineers. Lol
