Is the E550 the worst car Mercedes ever built?
I think Mercedes is partly to blame here by giving "free" sport upgrades to most E550s. I don't think most of their customers realize the durability tradeoff you make with those tires. The tires above all should get you to where you are going without leaving you stranded with wheel failures.
Unless someone really loves low profile tires and understands the risks associated, you should just refuse to accept a car with low profile tires. When enough people do that Mercedes will stop offering these silly fragile tires to people who may need something more durable.
Verdict: TROLL
I personally would not recommend anyone drive on low profile tire unless you drive on roads that are impeccably maintained. I don't think you actually gain much in performance with the low profile tires as far as the 550 is concerned but that is beside the point. I too used to have low profile tires and had wheel failures.
I changed to regular tires and I've never had any wheel issues since (knock on wood). In fact I will never buy another car with low profile tires. With low profile tires you get a harsher ride, fragile wheels prone to failure, and I really see no benefits.
Do you absolutely really MUST have low profile tires in your car? Would you consider regular profile tires in either 17 or 18 inch?
I don't think you should knock the 550 for your wheel situation though. It seems to be because of a wheel choice that is not conducive to your driving circumstances based on all your wheel failures.
It is a wonderful car and in that class/range there's nothing else I'd buy.

By definition, a low profile tire is one where the height of the sidewall is less than 65% of the width of the contact surface of the tire.
Since the manufacturer has specified the outside rolling diameter of the tire for a specific car, that outside diameter can be reached in several ways - small wheel and lots of sidewall or big wheel and little sidewall.
For appearances, manufacturers have been going to larger wheels because we as consumers think they look cool.
The problem is that any combination for our cars will be low profile - but the more sidewall you can add, the better your handling and the fewer risks of breaking something.




My rims get bent after any small road bump resulting in vibration when driving at speeds greater than 60 mph. Every 4 - 6 weeks I need to have my AMG rims straightened up. I have had about 6 rims and 8 tires replaced. (Luckily I have tyre and rim insurance and they pay for everything.) This is due to a fundamental design problem with the combination of the weight of the car, the airmatic suspension and the AMG rims resulting in bent rims after any small road bump. This is driving me up the wall!!
I now drive the car like it's a baby. Really carefully and really slow. Still having same problems with the rims. Today my car is at MB service AGAIN, getting 1 new tire and 2 rims straightened.
The only thing Mercedes wants to do for me is end my lease early so I can get another Mercedes. After so much trouble, why would I ever want to get another Mercedes? Ever?
PLEASE HELP. Any suggestions would be greatly appreciated. Thanks, Mark.
PS Prior to my E550 I owned a BMW M5 with racing M5 alloy rims - I NEVER had any bent rims. EVER. Same roads. Same driver, Used to drive a lot more aggressively.
I have a 2010 E550 with 18" AMG rims. Happened that I drove over something that looke like 2" thick square metal bar on an interstate higheay at 70 mph. Could not go around because of cars next to me.
When hitting it, it made a very big impact on both front and rear left side tires/wheels. Stopped immediately to inspect and was sure I had lost two tires and wheels but the front came thru unscaved. Rear wheel has about 3/8" deep cut in the outer rim and the tire got cut but not to reinforcement layers.
I stopped at the closest tire shop and the guy told me to just glue it as it was not a dangerous cut, which I did. He even said he could sell me the tire but would hate to do that as it was not necessary.
As a result of all this the rims in front or rear did not get bent or damaged other than the cut in the outer rim of the rear wheel. No vibrations, NOTHING.
Because of this experience and that you have gone thru multiple wheel changes I DO NOT BELIEVE YOUR STYORY.








I agree, it is very bad for MPG. My last fill-up calculated only 15.6 MPG on a half tank that I was driving almost all city and used my foot as hard as I could everywhere. Thought it would have given me at least 16.5 MPG.
But I absolutely love it when it goes when I ask...

Never again. I actually like the look of a substantial tire that will not wilt if I graze a curb accidentally.
Like I said earlier I think if Mercedes customers understood the tradeoffs in these silly fragile tires I bet very few would get them.
And this is not to take away from people who like low profile tires. If that is your thing that is great and you should enjoy that. My point is when you put them in your car, you know what you are getting yourself into (hopefully)! But your typical Mercedes buyer has no idea that Mercedes is selling them a product with inferior tires that are more prone to failure.
I really think Mercedes should stop installing low profile tires by default (unless requested by the customer), especially in a mainstream daily driver vehicle like the E class.

Low profile is here to stay.

My, advice, write your favorite legislator. Good luck with that.

Have you seen the 60-0 specs for the new E550 with the bigger rotors? I've always been disappointed with the approx. 130 feet stopping distance for the E class that ranks right up there with the huge Volvo XC90 SUV when Jaguar, Audi and BMW manages that in about 110 feet. The profile of the tires used to be 45% I think. Hopefully they can fit the rotors in with a profile around 40%. It's when you go below that that I think you start seeing most of the wheel failures.
The other day some idiot drifted into my lane and I had to swerve right a bit to give him some time to get back on his lane but during that time my tire made contact with the curb and I was afraid I damaged my wheel. I checked what had happened and my standard profile tires did a great job of handling the situation. The standard profile Conti tires actually has a bit of a rubber lip that goes around the edge of the wheel rim to protect the wheel. I saw some black rubber marks on the wheel where the tire compressed while protecting the wheel and the rubber marks washed away leaving a clean wheel. Had this been a low profile tire there likely would have been real damage done to the wheel from the brief contact.

18-inch AMG twin 5-spoke alloy wheels
245/40 R18 all-season
Legendary 18-inch AMG wheels are standard on the E550 4MATIC Sport Sedan. Their twin-spoke design features highly polished surfaces with painted pockets, and they're fitted with all-season tires.
And of course here is the disclaimer attached to the wheels being offered:
Lower aspect ratio tires and accompanying wheels provide substantially increased treadware, tire noise and reduced ride comfort. Serious wheel and tire damage may occur if the vehicle is operated on rough or damaged road surfaces or upon encountering road debris or obstacles. These tires are not designed for use on snow and ice. Winter tires mounted on appropriately sized and approved wheels are recommended for driving in those conditions.
