e92 335 on run flats - BMW 3-Series (E90 E92) Forum

This has been posted before I am sure but I was just wondering if it is worth changing my stock run-flats (225/40/18 and 255/35/18 bridgestone RE050A) with a set of non-run flats. I am actually having no real problem with the ride quality and so it is worth the bother changing my tires and rims. Your advise is much appreciated.

no don;t change it is my advice. The BMWs have cracked the puzzle in making the runflats work with their suspension, if you get off runflats, some cars act funny... as in it feels rather... more bouncy... (softer) Think of run flats as a set of rocks, the run flats are a lot harder than the non-runflats. If you change to non-runflats, change the suspension too, but then you will be looking at a whole new bill to calculate.
