Vibration at 48 MPH
I have a S class 2016 4 matic with run flat tires, every morning the car vibrates for a few miles and the the vibration fade away. I went to the dealer, fix the rims balance tires, check all system and they didn't fix it.
They told me that maybe are the tires, the are the Bridesgston 18" 400.
Any comment?

No I don't think that will fix it. I am running the normal non-run flat tires and I notice same exact thing in the AM especially when there is lots of temperature swing between day and night, and the longer it sets the more aggressive vibration would be until the tire rotates for few miles then it fades away. That's a very normal behavior of most tires. Tires expands and shrinks due to temperature increase and decrease. The surface of the tire that is touching the ground can't expands and shrinks due to friction and load of the car on the ground on that spot, and that makes the tire as a non-ideal circle. Once you drive for few miles in the morning, that allows the tire to restructure itself as it heats up and expand evenly over the entire surface area of the tire.

I'm thinking that is to much weight on the front of the S class 4matic, if you replaced with regular tires and still vibrating, my worry is that on long term, will damage the front drive, bushing, arms, bearings etc. Did you try to play around with the tire pressure? What brand of tires are you using?
Sorry for the questions but I'm trying for months to find a solution.
I appreciate your input.

Going back to flat spotting issue, run-flat and regular tires both will experience this. The best thing to do is to make sure that the pressure matching the specs of your car... flat spotting is just normal... different tires react to flat spotting at different levels.... maybe try different type of tires next time.
If you want to completely remove flat spotting, try these (see link below) from Home-depot in your garage and that should eliminate 80% of the issues. It forces the load of the car to be spread evenly accorss the surface area of the tire.

It's hard to answer with yes or no, it depends on temperature outside before you park your car, surface of your garage and whether it's cooled or not. Mostly you shouldn't see much vibration overnight, but probably if u r too sensitive to vibration u could develop some vibration by just having the car setting overnight but it should be very minimal if it's just 1 day. Again, it really depends on many factor including type of your tire, garage, temperature swing, etc.

For sure I notice it nowadays since my car sits more. I'm very sensitive to vibrations but if I know what it is and it will go away I don't let it bother me. Ii would imagine some tires are more prone to taking a set overnight that others. I think and don't hold me to this but my old Continentals were worse than the Michelins that I replaced them with and that could be simply because they were older. So depending on the age and the fact that they are run flats may or may not make it worse. What is your inflation? More inflation would tend to reduce the problem but give you a harder ride. I think the most practical solution is to not worry about it.
Edit: I just went up the thread chain and saw W222's tire savers. That might be a good solution for you.

Yes, why not!!!? The guy said he is very sensitive to the least amount of vibration, and tire spotting is a very known problem of almost any tire when car sets for an extended period of time, so why not to use it if he doesn't want to feel any sort of vibration later after days of car being garaged? People are using it when they store their cars, but there is no reason why to not use it when car is garaged for days if the owner doesn't want to feel the vibration the next day he drives it! Do you understand the physics of how tire saver works? and how they distribute pressure over the surface area??

Yes, I do believe the distribution I understand. I just think it's odd and sort of like a snake oil. I had many cars over the years, which were parked for a week at a time, or longer.....never any issue like this..........I had Pcars lose charge in the battery, but never a tire issue due to sitting without a tire thing mentioned here. Of course this is just my story, I know we all have different ones

I appreciate the comments, the vibration bother me because I purchased a $ 110,000 dollar car that ride worst that all my previous Mercedes.
I had 2 SL 550, 2 ML350, 1 E, 1 GLK350, 1 C-300 and never had this problem, never a vibration, only when the tires where out of balance.
My personal opinion is that Mercedes screwed the design of the front drive, the 4matic is very heavy in the front. The SL 550 have the same engine and not vibration.

Thank you for your comment, is very interesting.
Did you have the vibration with the Bridgestone original tires, or never experience this problem?
If you can can you let me know the specs of the Godyear tires.

I had this problem with a Lexus. Took it to the dealer and they said it was a "driving characteristic." Turns out it was a bent rim that they overlooked. Might be worth having them more carefully examine each rim for being truly round.

I've found Goodyears to flat spot. Seems like my Micheline Primacy 3 don't really seem to flat spot much, same with my Uniroyal Tiger Paws on my S550, then again they are made by Micheline. Having great luck with the Tiger Paw GTZ tires and like half the price of most tires, only drawback is in the hard driving rain they can hydroplane so you have to be more careful under those conditions.
