I'd driven enough BMWs over the years to clearly see the first cars I tried on RFTs, were compromised by the run-flats.
AutoCar ran a varied tyre test, on the track with a Z4, and quickly advised "remove the run-flats" and get the chassis that was masked by the RFTs.
Besides the Z4, it was clear the first E60/1 cars were compromised, the early E9* cars were also not sorted, far too many weird characteristics, besides the awful ride quality and unpredictable dynamics.
All sorted with a tyre change. As I've said for many years, BMW compromised the cars for RFTs, not designed them for RFTS.
Sure things have moved on a bit, but IMO, still not completely sorted.
I agree if the flagship M-Division used them and the purists were happy, then we'd have no cause for not using them.
If it is a safety product, then BMW's M-Division and Alpina should definitely be leading the cause.
