Following two instances of tire deflation within a span of 13 months, both of which were unable to be effectively re-inflated using a run-flat kit, I am now considering the purchase of a spare tire kit. I have seen that Kia offers such a kit for sale. Does anybody has any prior experience with this? The Kia Niro Spare Tire Kit is specifically designed to fit snugly into the storage compartment of your car. Although the product claims to be portable and provide a dependable spare tire, it is unclear how it can be accommodated under the rear luggage deck. Is there anything that I am not understanding?
