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 7‑65 and Loading the Vehicle on page 6‑32 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 7‑86 and Storing a Flat or Spare Tire and Tools on page 7‑94. After installing the spare tire on your vehicle, you should stop as soon as possible and make sure the spare is correctly inflated. The spare tire is made to perform well at speeds up to 70 mph (112 km/h) at the recommended inflation pressure, so you can finish your trip. 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. Do not mix tires and wheels of different sizes, because they will not fit. Keep your spare tire and its wheel together. Regular Wheelbase shown, Extended Wheelbase similar. 6.
