I'm sure I am jinxing myself...
Since 2007, I've replaced my run flats with non runflats as soon as I got a new vehicle that came with RFTs.
I've had exactly one flat tire in those 240,000 miles (I do 20K per year average) . It was in my driveway and BMW flatbedded me to their shop.
I'll take my chances with just a BMW flat tire kit and no spare.
(I'm sure I'll have my 2nd flat when I get to my car after work, but that's what I get for opening my big mouth
).
