A reasonable experiment would be switching from run flat to non-run flat of the same brand and model tire. That's at least attempting to hold everything, other than sidewall stiffness, constant.
My C6 Corvette Z51 is currently on Michelin Pilot Sport PS2 run flats. I'll be changing them out this summer and will go to the PS2 non-run flat. Will try to remember to follow up here with observations.
Don't know what tires the new X1 is coming with, but I'll be switching them soon. I'll probably go with Michelin PS2 or Super Sport, inspired by
PleaseAdvise's reminder of how good they are. I had the PS2 on my 2001 540i 6-Speed and loved them.
