From my order sheet, I believe that the performance tires are not run flats while if u choose all season tires, it is a run flats.

Also from what I see at the NAIAS, there were a cut out for small spare, definitely not full size, but I don't know if u have to buy that extra or not.

though oddly there's a mobility kit AND a jack? what's that about?

stoopid but for me no spare no car. I take road trips. oh well maybe s5
