I happened to be on the Kia USA website looking at the Niro and I found under accessories that there are two options in case of flat tires. The first is the goop + inflator option to plug holes, reflate the tire and drive as far as you can, the other is an actual space-saver small tire that fits under the rear deck and can replace a tire that is too damaged to just plug and drive. But, of course, you would not want to drive fast or very far on it. Those have to be purchased separately....I am still hoping it might be possible to put a trailer hitch on the rear and then a swing-out mount for a full-size spare tire, but that option so far seems to be not available, since no hitch option is on the Kia Niro website. Kia does apparently also offer an option for 24-hour service for flat tires etc.
