Your vehicle, when new, had a fully inflated spare tire. A spare tire may lose air over time, so check its inflation pressure regularly. See Inflation - Tire Pressure and "Loading Your Vehicle" for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Changing a Flat Tire .

After installing the spare tire on your vehicle, you should stop as soon as possible and make sure the spare is correctly inflated. Have the damaged or flat road tire repaired or replaced as soon as you can and installed back onto your vehicle. This way, a spare tire will be available in case you need it again.
