At first I thought the run flats sounded like a good idea. You save weight, save room, save gas.

Until I read that they not only have a harsher ride and wear twice as fast, but even worse are heavier with bigger thicker sidewalls, and have a much higher rolling resistance losing on average 2mpg!

As a cyclist I know how much centrifugal tire weight and rolling resistance matter to efficient forward motion.

So my list of negatives on the X1 is growing rather than shrinking. No MT. No diesel until next year. Now no normal repairable tires as needed in ski backcountry.

It's almost as if BMW is TRYING to get me to stay with MT+TDI+normal_high_mpg_tire VW/Audi! Nuts!

Does anyone know if you can order the car w/o run flats for ED pickup? Failing that, can I replace the RF's myself if I order the large 19" sport rims (ie, is there enough wheel well room)?
