    run flat replacement or not?

    Just got a flat tire warning. Taking in my 2004 645 in the AM and need to know how to approach the decision making. Any recommendations out there on brand of run flat or otherwise?
    Thank you in advance!

    Re: run flat replacement or not?

    I agonized for a couple of weeks over this about 10,000 miles ago. Ultimately I chose to stay RFT with the OEM Bridgestones. I heard the claims of softer ride and possibly quieter. Most of those that did change seem to prefer the PS2s. But these had their detractors as well. I like my ride, do not believe I had excessive road noise and my tires lasted 30,000 miles on rear and probably had 4-5k left in fronts but changed them all at the same time. I have done auto-x and extremely aggressive ToD (Tail of the Dragon) driving and I am pleased with performance of the RFTs. Could there be better, sure but by what margin? On the other side is the confidence I have in these tires in the safety factor in aggressive driving (and of course NORMAL driving). I had a bad blowout on a good condition Pilot Sport while doing some twisty driving years ago and I guess that extra margin keeps me in the RFT camp. I also have been fortunate in that I have had no punctures or other problems that some have had so I have not had to scramble looking around for a tire when they are in limited supply and availability. I purchased my replacements from Tire Rack and they shipped to my BMW dealer for install. About $40 each mounted and balanced. OBTW, this is the first car Iíve had that went from 0 miles to replacement (30K) with no vibration or any work on the tires at all. The replacements have been just as solid as the first set.

    I just bought 2 OEM rear replacements, unfortunately from the dealer. I too am happy with the performance and comfort of them enough to stay "run flat".
    Thanks for your post!
