I don't think I've ever actually read/heard why BMW has gone the RFT route so early in it's "technology life-cycle"?
I assume they believe this is the future of tyres and road safety, so have chosen to get a step ahead of the competition by adopting the technology now and integrating into its new-car design.
In the German press they typically lose the Comfort part of the group-tests and the magazines often explicitely state this is because of the RFTs, not just the more "sporty" suspension set-up BMW has over the competition. I just hope the technology improves quickly, because it is obviously a significant weakness in an otherwise very good package BMW offers.
Anyone "formally" know why BMW have gone this route?

I understand that, however why do this now? By doing it now, they provide the customer with a "positive" and also a "negative". Why not wait until it is only a "positive", i.e. when the RFT technology is developed enough to also provide the required comfort standards? I assume this is what the competition such as Audi and Benz are doing. Ah well, I guess its a case of "it is what it is"!

So if RFT are better than non RFT then why don`t the F1 or rally cars use them?

My Ride: 2005 525i : Alpine White, Steptronic, Black Interior with Amethyst Leather & Popular Grain Brown, 17" 122-Style Rims, Adaptive Bi-Xenon Headlights, Auto Dimming & Folding Mirrors, Advanced A/C, Sports Steering Wheel, Electrically Adjustable Steering Column, Extended Lighting Package, PDC, Sliding Armrest, Bus Navi, Hi-Fi Sound System (MP3 DVDs), CD Changer, Rear Sunshades..
MODS:M-tech front bumper, Painted Grill, Installed Aux-In, Garage Door Opener (Overhead Compartement), ///M Steering wheel, Wood hand brake trim, Wood gear-shift lever. 35% Tint all around..
Got, ACS Roof Spoiler, but not installed..
i have a spare tyre in my car, and i still have the original bridgestone RFTs they are EXTEMELY noisy, a little embasing even...
but to be honest on a dry road turn they perform very well because of the stiff sidewalls, i dont mind if i lose a little bit of comfort if it gives me a little extra performace this will be my first full season of wet weather in the car, last year took it too late and didnt ran more than a couple of days, so ill see this poor went performance... it doesnt matter to me we get like 14 wet days a year (max)...
but most people dont like to change tyres so its a plus to them, my father woke me up a few months a go to change the tyre on his car after a puncture... he also once called me up when driving my car said it had a puncture at least in my car i told him i'll check it when you return.. its a reall PLUS for some people...

3. Only drop in performance was a less sharp 'turn in'.
