I took delivery a brand new E53 last week. I drove it home and felt like the tire is so stiff and harsh ride. first I thought dealer over tires pressure. But after I checked they all under like 4-5psi each. Do you guys have any issue with Pirelli runlet tire?

runflat tires will always be harsh. Maybe adjust your tire pressures (in the mid 30's) and see how it goes.

Yup run flat tires ride slightly harsh and don't handle quite as well as non run flats.
The door says all 4 tires at 44 pounds. I assume you are in normal mode not sport
or sport plus which stiffens the suspension. On Porsches they had a comfy mode
tire setting which worked well.

What are you comparing the rough ride to ? Your previous car or something?

1. They are Pirellis.
2. They are runflats.
3. The combo of 1+2 is your result.

Really tho, the 212 and 213 both have way too much spring and shock rates for America. Mercedes has got to find a way to find more compliance in these things, not to mention how they are going to fall to pieces with about 80k miles on them from harshness and impacts.

It's a matter of where you're coming from. The American wife and I were both surprised at how comfortable the OEM runflat ride was even in Sport+. Her old Audi S5 was a bit harsher and my Volvo is worse, both with Conti DWS'. I don't think it was the tires though as she's got DWS' on the Merc now after she cracked a wheel and the ride is still pretty plush.

I already set to 35 all four corners, but still. I know I can't compare to my F01 750il with run-flat. But my 7 front tire is 245/40/20 and rear 275/35/20 compare to my new E53 front 245/35/20 and rear 275/30/20. they are pretty close in size. So I'm so curious about this Pirelli. I ask my friend to drive his M550i with OEM run-flat with the same size set-up like my E53. Sure enough The M550i is ride much better. I think the Pirelli that come with my E53 is not a good tire at all.

as allenjdmb said, Mercedes AMG cannot do a suspension setup like BMW or Porsche can. Did you happen to test drive the car before purchase, I lonely ask because do you find much difference to what you perceived to feel prior vs now? Very unlikely but it’s somewhat possible dealership left the foam suspension blocks in during PDI - unlikely but I’ve heard of that happening before.
The ride of a 750 is going to be much different than a E53 no matter how similar in size the tires are.

bobblehead

yup. the bmw 7 series is luxury comfort car, just like the S class

paul325740

I did test drive before I purchase.but it was on a very cold day and rain around 32F ( maybe tire pressure were lower from the cold temperature ) I was noticed right away the car is not smooth like my 7 but it was acceptable compare to the performance and look of E53. Since I got E53 for weeks, temperature was around 50-65F all the time. I think is a bad tires
again I compare the ride with my friend M550i with Goodyear run-flat. His car is ride much better. also, how to look for foam suspension block?

paul325740

I'm did not compare to my 7 at all. I wish Mercedes put a better tire and adjust suspension better for USA market.

I hate runflats

i hate the oem runflats on my 19" 550i bmw rims; will def be getting regular tires and a spare next time for that car

paul325740

I lease this car for 3 year. I don't think the OEM tire will last for 3 years anyway. I will replace with either Non-run-flat Michelin A/S or Continental DWS. and keep Pirelli for lease turn in. Do you guys have experience with these two?
I can't deal with this Pirelli run-flat tire!

In my experience (and a lot of others), Pirelli < Michelin, period. It’s the most widely accepted opinion I’ve ever seen in all of cardom. With that being said, most ride quality issues are caused by “naively high” tire pressures. The tire pressures listed on your door jamb are the cold pressure set-points for a fully loaded vehicle at its maximum rated speed. AKA...WAY too high for normal driving. For Mercedes, at least on my E63, you have to look at the tire pressure table inside the fuel filler door for other acceptable pressures. I’m using the “M+S” tire pressures, which for this car still seem pretty high, and it’s 39psi front and 36psi rear. As another example, for Porsche, you have to spend 20min thumbing through the owners manual to find the table with the “comfort” settings for the tires and how to adjust the TPMS settings accordingly (I know because I just did it). Their comfort pressures are certified up to 155mph, so it’s beyond me why anyone would run anything different. Which, BTW, on a brand-new Porsche 992 is 29psi front and 30psi rear.

paul325740

I just add air to recomended " Min " 41psi all 4 corner. and driving around the same route to work and go home. It ride smoother than 35psi all four corners. But it still to stiff.

I recently made the change from run flats to non RFTs. Day and night difference. I got the Hankook Ventus V12. Not as great as the PS4s, but very very acceptable for half the price. I am finally starting to like the E53 after this change and pissed at myself for not doing this earlier.
Do yourself a favor and change now. Maybe list your tires on FB/ CL etc and recover some money, or keep a spare set since you wont have a spare with the new non-RTFs.

Brand new e53 amg drop top, run flat tires at about 45mph, in a pot hole, and the entire tire split and the wheels buckled. Rides very harsh, looking to replace with non-runflat tires. Can anyone recommend non run-flat to replace the tires?

lkfoster

We put Continental DWS' all around on after the cracked rim. They have been our go-to tire since they first came out and have been happy with them.

Traction wet and dry is pretty decent. Ride is a bit harsh to me now that I have Audi's version of a F-150 pickup with air suspension and noise dampening tires but it could also be that I'm getting older and the wife's habit of running around in Sport+. Tire wear after around 20k miles is OK, especially with their 50k mile warranty. I have found it curious that front tire wear is around 2X that of the rear. My old C55 AMG with the boat anchor V-8 ran through DWS rears at 2X the fronts.
