My used '17 came with '14 rims powdered black and the inflator. I suspect it was factory spare and the prev owner kept a '17 front as a spare, but when he sold the car to Permian, he sold his '17 set on the side and either the seller or chevy put the inflator in the trunk. The inflator was attached to the long threaded rod that keeps the spare tire in the trunk, so that's why I suspect the car was factory spare. I don't know what a factory inflator trunk looks like and how the inflator is mounted in the trunk. I wanted a real spare, so I bought a rim and tire. I didn't have the factory jack kit. I shadowboxed my trunk with a breaker bar, torque wrench, jack stand and floor jack. Single, so no need for a real trunk for luggage or Costco.
