Depending on the trim level of your Equinox EV, the car has 19" wheels, standard tires and a tire inflator kit, or 21" wheels with self sealing tires (no repair kit). It does not have run flat tires.
So, what's the difference between a traditional tire, a self seal tire and a run flat tire?
Traditional Tires
The traditional tire on the 19" Equinox EV wheels will deflate if punctured by a nail, screw, etc. Depending on where the puncture is located and how large it is, the tire inflator kit can be used for a temporary puncture seal and re-inflation to get you someplace for a permanent repair or tire replacement.

Self Seal Tires
The self seal tire on the Equinox EV 21" wheels will not deflate if punctured by a nail, screw, etc. Depending on where the puncture is located and how large it is, the tire will seal the hole. A sticky, viscous sealant layer fixes tread damage up to 5 mm in diameter. It traps the air inside, keeps the tire inflated and your car mobile. It works instantly, even if the puncturing object becomes dislodged. Depending on the picture size and location, the self seal is a permanent fix. The tire should get inspected to determine if it needs a plug or interior patch. Self seal tires can be repaired following the manufacturers instructions, but some tire shopsbrefuse because it's a bit messy and takes time to do it right.

Run Flat Tires
The Equinox EV does not have run flat tires. Run flat tires are like traditional tires, but are designed to be driven on even when the tire has lost all air due to a puncture. They are referred to as self supporting tires. There are two different technologies used, one uses a much stiffer sidewall for the tire preventing it from riding flat, the other uses a ring of supporting material inside the tire between the tire and the wheel. Like the stiff sidewall approach, this prevents the tire from riding flat when air is lost.
