yes, it's the OEM run flat tires (dunlop sport maxx). there is no air in the tire but i was able to drive away about 1/5 mile to get home. the tire made funny noises while driving... so i went slow, just in case. it seemed to hold up... but it 'sounds' like it's flat. i'm not sure how it would feel on the highway...

the pothole was a pretty descent size... but i watched other cars go through it without issues... these low profile tires are partly the problem i guess... but for some reason, i feel like my old 19" Michelin Diamaris tires on my old 4.4 were stronger than these 20" tires on the 4.8... but that might be 'psychological'.
