Whatever your situation of coverage or foolhardy courage, I second that you should not try to use that foam stuff if you can avoid it. What they do not tell you is that although it can sometimes get you rolling again, it will probably ruin the tire, and if left in for long, can ruin the rim as well. If it works, it's almost certain that the hole in the tire is small and repairable already. If that's the case, and if, as in many cars, you also have expensive alloy wheels, you should think very hard about the relative cost of a quick repair which may or may not work, versus waiting for service.Most new cars, especially EVs, don't come with spare tires. In case of a flat, I am not even going to try to use that foam stuff. I am calling roadside service.
I have a AAA membership, roadside assistance provided by the car's manufacturer, and "free" roadside assistance through my not-so-free credit card. So, I'm covered.
The same goes for do-it-yourself tire plugs (the rope type plugs you can easily get in kits). Once considered OK (and I've used them many times without incident) they are not considered legal, and many if not most tire dealers will not touch a tire that has been thus repaired. If you're riding on old skins and don't want to be stuck in the wilderness all night, plug away, but be sure you've calculated the relative cost.
