My Ride: My ex-ride: EU '08 LCI 520dA. Space Grey, Sport Seats in Black Leather/Fabric Anthracite, Sport Steering Wheel, A/C with Extended Features, Hi-Fi Speakers, Cup Holders, Cruise with Braking function, Folding Rear Seats, Xenons, Park Distance Control.
I now got the answer from GoodYear Dunlop Tires Nordic when I complained about tire vibrations.
The answer is fully quoted below, but I did change my sir name.
Dear Mr. Ricracing,
there is a phenomena called morning flat spotting. This you can experience
in all high performance tires and is due to a reinforcement layer of nylon on top
of the steel belts that is laying under the tread area.
This is a well know phenomena. But, this phenomena can only effect the
performance in a few kilometers in the start of a ride after parking
several hours or in the morning after over night parking. If you experience
vibration still after max 10 km then you probably have additional factors
contributing to the vibration.
I recommend you to contact your tire dealer who mounted the tires to review
mounting and balancing as well as centering of the assemblies on the axle
hub etc. This to exclude the most common reasons for vibration problems.
You are welcome to contact me if you have any further questions.
Best regards,

So what are your plans next to get this resolved? Another road-force balance?

Note, that I have not re-balanced them yet.
Look into matters first - then act, say I.

Make sure they balance and road force them and ask what numbers each tire came back with on the road force. At least then you'll know they actually did it. Someone on here not to long ago posted the acceptable highest number for a BMW 5 series (want to say 18) but do search and see if you can find it.
