Maybach Eating inside edge of the tires update
Hi all. I asked about this before and some of you had some amazing recommendations on what to do about the car eating the inside sidewall of the tires (especially REARs).
I took the pressure of the tires up to 47 on all corners and we drove from Florida to Atlanta last weekend. When we stopped for gas I would run my hand across the tires from side to side. They were simply warm uniformly.
Perhaps the person that suggested raising the pressure was onto something. By the way the car drives no different in normal driving.

Perhaps it was I.
I run my tires at 38 PSI. Recently, the wife and I did a 5,000 mile trip from Austin to Berkeley and back over 2 weeks and averaged 24 MPG in the S600.
I would be under the notion that 47 PSI is probably a bit too high, you should get similar low wear and similar mileage and slightly better ride closer to 40 PSI than 47 SPI.

Hi Mitch. We had a rather long previous discussion about this. I meant to say this is an update. I will say that at 40psi we were getting inside sidewall rear tire failure.........

Is that Cold Pressure? 47 Cold can easily go over the possible MAX pressure of the tire. What is the MAX tire pressure, and do you inflate cold or is that the warm / hot pressure...

I keep mine at 50 all around , all the time. I now have 22,000 miles on staggered tires and they look to still have 40% tread left. I also keep the suspension in Sport mode at all times. Before I did this, my tires were at 35 pounds and I kept it on Comfort and within 20,000 miles , I ate up 2 sets of front tires. I do the same for my motorcycle and my Goldwing gets 15,000 miles on a set of tires, which is twice what most cyclists get.

I noticed that I had a similar issue with the W212's Michelin Primacy tires .Funny thing was that only rear tires seemed to have worn out while fronts were having a good tread .I kept them at 38 psi which was thought way too high but it was OK to me . 47 PSI seems too much but I would consult what manual says

The max pressure on the side of my tires says 50. Hence 47 cold setting.
The problem is the car even with factory alignment will eat the inside sidewall of the rear tires and cause a total failure. In 50,000 miles we have had two failures like this. The tire tread is still in great shape but the sidewall is torn up. The first thread for this issue is here.
https://mbworld.org/forums/new-s-cla...ear-tires.html
Taking some recommendations from some very informed people in the previous thread I decided to try a higher pressure which supposedly makes the center line of the tire take more of the load of the car. As I said earlier I ran my hand across the tires and felt no hot spots when we would stop for gas.
There is nothing more annoying than to be driving along and get the message tire failure........... Had it twice............ NOT fun. It also sucks to spend close to 1000 dollars on two tires that look like they are in great shape but this sidewall failure happens......

The way I drive, I could probably get 40 to 50,000 miles out of a set of tires. However, to me, ride comfort, quietness and safety are paramount. So, when I get somewhere around 18,000 miles on a set of tires, I get new ones. I like driving on the first half of tire life. These cars we drive are expensive, luxurious cars. $1,000.00 to $1,200.00 for a new set of tires is pretty much nothing in the greater scheme of things. And, lest you feel that I throw money away, the used set of tires usually sell very quickly on Craigslist for a few hundred bucks.

I just spoke to the service director at my local dealer and we both believe your alignment is off. Reason:
1: The S class as heavy as it is ( about 5,500 pounds ), the tire wear should be on the outer tires and not inner tires. Like a member mentioned here happening on the E63 which is what I also saw on my previous E63s which is very common on the W212 AMG E63 forum.
2: With the OEM continentals, Michelin and Pirelli tires which is a softer compound taking corners even making a U turn at any speed high or low, the outer tires gets worn out fast because it is such a heavy car when taking a turn pushes the outer tires to its limit.
3: If you are using a harder compound tires, the car will drive rough, but tires gets worn out slower, but that is the trade off using harder tires.
4: Dealer recommended cold 48 pounds inflation.
Hope this help.

I made a mistake. I meant to say in the title of the post that this is an update to a previous post about this problem. I did take the car to a reputable shop and had the alignment checked and it was correct. I realize they are not the dealer............. Adding pressure to the tires was one suggestion of many really smart suggestions.
The car has the OEM tires and I was running the pressure at what the car labels say to but was having tire failures where the inside sidewall of the rears were being eaten away and of course the tire fails. Of course the rest of the tire being the treat part is in great condition................ I learned adding pressure gets more contact pressure added to the center of the tire and as I stated it seems so far to have helped keep the sidewalls from getting hot.......

Yes I got you there but the S class does not have any camber adjustment for the rear. You can buy adjustable camber rods but I decided to try higher tire pressure before I go any further. As I said in the post I felt across the tires when we stopped for gas after hwy driving and there was no notable difference in the sidewall or thread area temperatures. They were simply warm that is it.

Hopefully you whipped it with tire pressure.
FYI assuming proper alignment, over inflation will accelerate center tread wear and under inflation will accelerate edge trend wear.
Also, camber and toe are apple and orange but improper settings for either can give you similar wear patterns of the other.
Good luck

1. A tire's maximum inflation pressure is the highest "cold" inflation pressure that the tire is designed to contain. So 47 psi is ok but will reduce comfortable level. Ok as a work around till the issue resolved.
2. do you use oem wheel ? looks to me that the wheel/rim offset is incorrect, offset number too high
3. do you use oem tires, if rft, do you use MOE tire recommended by MB? Need "XL" Load Range to handle the load.
4. any scratch markers on the suspension components where eating the tire ? Must have. Dealer service should find some and it may be bent or damaged
hope you can solve the issue soon. Any normal car should not do this.

Hi MB. Everything for the car is totally stock with OEM tires and wheels. As I said adding pressure made no difference to how the car rides from anything I could tell. I intend to drive the car as it is and see if I have any more failures. If I dont then I think I figured out that the car requires higher tire pressure than what Mercedes says. Now it is an S class but heavier and has heavy load tires vs standard load tires.
I dont know if anyone else has had this problem with any W222 cars but if they have then what I did COULD be a way to fix the problem. As I said the car rides exactly the same as it did with the factory tire pressure.

yeah I hear you. but I still see this is a work around till find out the issue. It is not normal. What if you get flat tire on a RFT tire ? You may not be able to drive under that condition.
Another possibility is that the car got wrong disk from factory so the offset is off. Taking wheel off and check the part number on the disk and make it is for your car. You really should check with dealer and MB to resolve issue.

So I think this was discussed in the original post. I did talk to the dealer, I talked to the tire place that checked my alignment, I checked with other Mercedes owners. They all said that these cars are known for this issue. The way it was said is the cars are set up to drive at 140 on the autoban and not 70.
So we have had THREE rear tire failures in 50000 miles and every time the inner side wall literally is eaten away and has holes in it and you loose your tire pressure. The rest of the tire looks great.
So as stated earlier I did one of the simplest things and that was to add pressure to the tires and as I said the car rides exactly the same as it did before. The tires did not have any hot spots on them when we stopped to get gas. I have a feeling that this MIGHT solve the problem.

I agree with mb1000, there is something wrong with the car. No MB car should wear the tires as you describe. I am friends for over 10 years with the local MB dealer’s service manager and he never BS’s me. He says the Maybach should not do that. My S65 does not. At 36 PSI rear and usually one or two people only in the car the tires have worn even across the tread and lasted about 20k miles. Most of the miles were with the cruise set above 80. What your car is doing is just not right.

Tire pressure according the the sticker on the fuel cap door is front 38 psi rear 41 psi.... I thought you might want to know that since it is not 36 psi.

Actually, that is not the rear tire pressure for the S65 which comes without the "run flat" tires. The S65 has AMG specific extra load tires with a speed rating of (Y). The bracketed Y means the tires are tested and certified for speeds above 186.
The manufacturer specifies pressures that allow the tire to perform safely up to its speed limiter setting while assuring the car will understeer when pushed to its limits. The S65 has four recommended pressures for the rear tires depending on planned use. Two people, no other load and not in excess of 155 is 33psi rear. Same but with 4 passengers and maximum load is 39 psi. When I plan to carry 4 people plus luggage on a trip I raise the rear tires to 39 psi but that rarely happens. For anticipated driving at the 186 limit the rear pressures should be 44 or 51, depending on the load. I do not anticipate driving at that speed in the US.

The tires on our car are also y rated heavy load run flats. The car tops out at 131 and I don’t have a star scan tool to remove the top speed limiter. On the plus side the AMG GTC has no issue going up to 143 and that’s about as fast as I wanted to go. No idea where the speed limiter kicks in on it.

I am curious what speed rating tires came with your car. If you have a chance sometime look at the small numbers on the tire and see if it is a Y or a (Y). Y is up to 186, (Y) is over 186, the exact top speed rating is application specific. The downside of the ultra high speed tires is they tend to ride harsher.
I do not think a scan tool will pull the top speed limiter. I know most of the aftermarket tunes like Eurocharged and Renntech do if it matters. I do not drive anywhere near that fast on public roads but perhaps I get to a track and try it out.
I was at Laguna Seca over the weekend driving all the AMG fleet. A lot of fun but they make sure the maximum speed is under 100. I saw about 102 in both the GT-R and interestingly in the SL63, but the instructors keep a real close eye on you if you drop back too far and then run up fast on them.
