Do M3's come with RFTs?
Do M3's come with run-flat tires on either the 18" or 19" factory wheels?
It appears that the answer is "no" and you just get the Mobility Kit...kind of surprising considering that BMW provides run-flat tires on the 335. Then again, I would actually prefer to not have RFTs for ride quality. Thanks. |

bmw also provides a TT 6 cylinder in the 335...does it surprise you that the M3 has a different engine? RFTs have obvious performance limitations and BMW, to my knowledge, has never put RFTs on any M cars.

Plus: the RFTs are ridiculously expensive. I'm glad the M3 has cheaper tires so I don't have to worry about tire costs when doing power slides |

i'm not entirely sure, but i thought that it had to do with the fact that the sidewalls on RFTs are much more rigid than regular tires. you're right that ride comfort suffers too. maybe another member knows more about RFTs vs. regular tires performance wise.

RFT's usually put up about the same lap times as their non-RFT brothers. There is some evidence that RFT's might not be as good for acceleration from a dig. |

Runflats
In 57k miles with my E46 M3 on 19" PS2s, I've had three slow leak punctures, but no "flats" or blowouts. You can repair a normal tire, unlike runflats. That, together with the ride issue, makes me favor this direction. I carry a plug kit and you have a compressor with the MMobility kit. In addition, on trips, I take a space saver spare. I'm happy with this vs. runflats.
