Wheel vibration - VERY frustrating
I've had the tires balanced on one of those rolling road machines and I just replaced the original Conti tires with Bridgestone Pole Position RE960. Problem still persists.
I'm taking it back to the dealer on Monday. What should they be looking for other than the standard wheel balance and tire wear?
Any help would be MUCH appreciated!!!
Thanks.

1. Balance was done
2. Alignment, by Mercedes. When the alignment was done by Butler Tire, they did not adjust the "spline" bolts. MB has the tools to do that.
3. New tires, due to the alignment not correct cupping of the rears were really bad. On the inside of the left rear the belt was showing. BTW- I am using Michelin Exalto's A/S. Very long lasting performance all weather tire, over 35K miles out of them.
4. The suspension was looked over to ensure fittings, bushings were all good. The SA told me they need to be replaced every 100K. I had that done at 105K, so I was good.
After this, issue was resolved.
Anybody out there have any thoughts on why the vibration is worse when first starting out?
Many thanks for the advice so far.

Most of the time on a COLD tire that vibrates is that the rubber has a Flat spot from sitting and goes away when warm
Several things to look at
Bent rim
out of round tire..even new tires have defects
MB has a few TSBs on this ..have the dealer run the MVI to see if the car needs the updates
Did the Tire shop line up the dot on the side wall of the tire to the valve stem? as most tire shops forget or dont know how
THis is unnecessary and a poor method since some rims have flat spot on them not near the valve stem and majority tires do not have a mark on them to line them up. Just use the Hunter GSP 9700 road force machine to get the road force pounds below 10 lbs for each tire/rim combo. Any road force number above 15 will cause vibration on Mercedes, BMW, Audi, and Lexus. Michelins are tires that rarely ever need to be roadforced on new and used rims since they are more uniform and round than bridgestone, contis, dunlops.,etc.
I told RCRo that brigestone tires are common to be defective and vibrate when new from factory *thats why they are junk. His older contis vibrated since it wore unevenly since contis are know to do that over time.
Even though I read many positive reviews (on this forum!) on the Bridgestones before buying, if I did want to switch to Michelins, would the tire shop take them back after they have already been mounted and driven about 100 miles?

Check out tirerack.com.
Check out this webpage and go to the bottom. It says 30 day try out guarantee.

I put 900 miles on mines before giving it back in 3-4 weeks.

very interesting, thanks!
What I did find,,
1) All of the other tire brands I bought except michelins were made in Japan
2) They all had Made in Japan stamped in the sidewall reguardless of brand name
It appears the Michelins are spiral wound seamless belts where the other tires have a belt with seam. This makes a major difference in the tire rolling. Also given all tires that say Made in Japan with different mfg's can't help but wonder how many companies actually make this tire or do they have 1 company make the tire with a different mold and their logo on it.
So If I have a wild guess. Michelins are made in USA and others would be made by one company with different names to save cost. Therefore given the belt design of the tire the Made in Japan tire just doesn't run as well on a MB as the Mercedes. Perhaps this is why the last S500 I looked at in the show room had the Michelin's Pilots same as I use on my E500.
I'm sure they are both good tires and each has their following. I certainly appreciate and value all of the advice.
Still waiting to hear the final diagnosis from the dealer on my vibration problem.
I also appreciate the advice on the tires (Bridgestone vs. Michelin). I think I'll stick with the Bridgestones, but next time will probably go with a touring tire vs. ultra performance. After all, how much ultra performance do you need on a station wagon!
Thanks again.

FYI - i balanced all the wheels and did full alignment and everything was in spec except for one bent rim (doesn't look bent at all - i have rims that are bent worse and aren't as bad to drive on). I replaced the tire/rim with a snow tire/rim which ran smooth the last time i had it on but the problem persists.
