I ditched the run flats, but have not had a flat tire yet. My wife is the primary driver.

I have the 3rd row seats. In the back storage compartment I have a 12v powered air compressor, plug kit, and a can of fix-a-flat. I also have roadside assistance through my insurance company. My mentality is this: when we travel for vacation/longer trips I will probably be able to fix a flat tire on the side of the road. The fix-a-flat is there as a last resort. In the event a tire is irreparable I would have to use roadside assistance. When my wife drives, I can stop over and help her out if I’m nearby, or she can use roadside assistance. I don’t expect her to be able to change a flat tire on the side of the road, especially with large SUV tires.

My daily is a Tesla Model 3, it does not come with run flats and has no spare. I have almost the same setup for supplies in my vehicle.
