You can purchase a replacement Jeep Liberty tire cover online from stores such as JCWhitney. Alternatively, you can purchase these covers from retailers such as Amazon.
The tire on a Jeep Liberty is changed by loosening the lug nuts, jacking up the vehicle, removing the lug nuts, and taking the tire off. A replacement tire or spare is then place over the wheel studs and the lug nuts tightened down.
