They make my dog carsick though. (I think) She is fine in our other cars.

Get rid of the stupid dog then. Problem solved!

car would always go first. right OP? Totally understand your concern. Did you check other things? My concern is that some cars leach the fumes into the cabin and this is what could make your dog sick. You might not even smell them, especially if the CO gets inside in tinny amounts, but it is not safe and your dog might be a canary in the mine. Your first line of defense if there is truly a problem. Dog is sitting pretty low, lower then you so might be exposed if any gases accumulates
in the lower areas of the car so he can sense it sooner then you?

Also it might be something you clean your seats with if it is a leather or fabric cleaners?

Or.. it might be off gassing of the faux leather seats? just guessing.. some dogs are sensitive to all kinds of smells.
in much smaller amounts then humans.

BTW.. here are the symptoms of CO in the car for people but maybe your dog is experiencing those symptoms?
How do you know if there's carbon monoxide in your car?
If you experience any carbon monoxide poisoning symptoms, even if the detector alarm hasn't sounded, get everyone out of your house into fresh air immediately.
...
The first symptoms of carbon monoxide poisoning include:
Chest tightness or shortness of breath.
Tiredness.
Nausea.
Confusion.
Headaches.
Dizziness.

What kind of car do you have? There was something about some popular brand that also was used for police cars that were leaking CO to the inside? Don't remember which brand though.

Pros: When I hit a pothole on the beltway at 9 pm on a Saturday, in the rain and alone, my car could limp home.

Cons: Most tire shops don’t stock the tires I use, and tire rack isn’t open on Sundays, so it was Tuesday before I had my car back.

So in OP’s hypothetical, i would limp on my run flat until the next exit with a service station (if you’re on an interstate there will likely be a service station with a mechanic close to a Days Inn within 50 miles), unless the car was undriveable, in which case I would call AAA.

Then I would place my tire rack order to that mechanic, and make a reservation at the Days Inn.

If the run flats make you uncomfortable (or make your dog car sick??), you can switch them to regular tires. Then you could conceivably have the aforementioned mechanic patch the tire instead of waiting for a tire rack delivery.
