Spare Tire 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 on page 5-84 and Loading Your Vehicle on page 4-50 for information regarding proper tire inflation and loading your vehicle. For instruction on how to remove, install or store a spare tire, see Removing the Flat Tire and Installing the Spare Tire on page 5-102 and Storing a Flat or Spare Tire and Tools on page 5-114. 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. 7. Make sure the tire is stored securely. Push, pull, (A) and then try to turn (B) the tire. If the tire moves, use the wheel wrench to tighten the cable. 8. Reinstall the spare tire lock (if equipped). Your vehicle may have a different size spare tire than the road tires-those originally installed on your vehicle. This spare tire was developed for use on your vehicle, so it is all right to drive on it. If your vehicle has four-wheel drive and the smaller spare is installed, keep the vehicle in two-wheel drive as much as possible. If your vehicle has a spare tire that does not match your vehicle's original road tires and wheels in size and type, do not include the spare in the tire rotation. 5-117
