I have a 5 series bmw (f10 latest one), and I have had other premium cars before and I (and many car experts) can tell you nothing comes close in this price range in terms of handling and comfort of BMW, run flat tires make no difference for me compared to regular tires on my previous Merc and my friend's audi a6.
Why downvoting? It's my personal experience and opinion? Sometimes I don't understand HN users...
I didn't downvote you, but I'd guess the reason was that you brought an irrelevant fact to a discussion about run-flat vs regular tires - it doesn't really matter if a BMW with run-flat still has better handling than an Audi with regulars.
