No doubt about it, run-flats of any brand contribute to tramlining. Had a new 330i with bridgestone RF's as a loaner, and of course with no staggered set-up, and they tramline also. To me this is the most annoying thing about RF's.Sure the firm ride is a problem, but to me, the tramlining is even more of a problem on the roads in the NY area. Just put my Dunlop none RF snows on and tramlining completly gone(and so is the extra firm ride). The car is once again a delight. Now once they replace my broken rear window that blew out on me, I will be back in business.

I had to look up the definition of 'tramlining' but now I know it is what I have experienced several times when I hit a lane divider and it feels like the car takes a small slide. I was really surprised becasue I've never had a car do this before (maybe I always stayed in my lane before

I put new shoes on today and the car is totally transformed ... in a good way. 
Goodbye Bridgestone RFs, hello smooth ride.
I finally put on winter tires (Dunlop Winter Sport M3s) today and the ride is much less jarring and tramlining is gone, gone, gone.
Ahhh, much better. 
Finally, this is the how the E60 is supposed to ride.
Interestingly, I found myself driving way over the speed limit several times today.
The usual feedback from the somewhat jarring ride of the RFs is gone, so I need to learn to pay attention to the HUD again. 
On another note, I put size 245/40 18" on all corners - using the original wheels, even though the 550 sport comes staggered. These tires fit the wider back wheels just fine and they look good all around. And the snow performance is excellent ... no more sliding around on RFs.

I think the tramlining is a function of the tire size more than the tire's composition (runflat/non runflat) -- the wider and lower the tire, the more likely it will tramline over ruts, etc.
As far as the ride, well sure the snows are going to be more forgiving and less harsh but they're not going to corner/handle as well as the higher performance tires.
It's difficult to have both great handling and a soft ride (and each of us may have a different, subjective opinion as to what that means exactly.) You either soften the ride at the expense of decreased handling or you live with a stiffer ride and keep the handling. Unless I'm totally missing something here, it sounds like those of you that like the ride on the snows better than the ride on the runflats (sport package tires) probably shouldn't have gotten the sports package in the first place.
For me, I prefer the summer tire experience over the snows and I'm more tolerant of the tramlining and harshness because of the handling capabilities the runflats allow. With the snows, I think the car rides like it should for a car without the sports package...

Could you guys summarize and explain the meaning of the term "tramlining" for non English Language Natives?
Thanks

On a multi-lane highway, many of the lanes are severely rutted from heavy truck traffic. When you follow through those lanes, or if you do a lane change, you'll quite often find that your vehicle almost has a mind of its own. It wants to follow those ruts. And some vehicles can really duck and dive when you're passing through them. The wider the tires on the vehicle, the more of the problem that you'll have with tramlining.
