Full-Size Spare Tire Your vehicle may have a full-size spare tire, which, when new, was fully inflated. A spare tire may lose air over time, so check its inflation pressure regularly. See Inflation - Tire Pressure on page 385 and Loading Your Vehicle on page 290 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 406 and Storing a Flat or Spare Tire and Tools on page 418. Your vehicle may have a different size spare tire than the road tires originally installed on your vehicle. This spare 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 different size spare tire is installed, keep the vehicle in two-wheel drive. Notice: If your vehicle has four-wheel drive and the different size spare tire is installed on your vehicle, do not drive in four-wheel drive until you can have your flat tire repaired and/or replaced. You could damage your vehicle, and the repair costs would not be covered by your warranty. Never use four-wheel drive when the different size spare tire is installed on your vehicle. 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 62 mph (100 km/h) for distances up to 500 miles (804 km). For heavy payloads or towing, and for low traction or four-wheel-drive conditions, repair or replace the full-size tire. Have the damaged or flat road tire repaired or replaced as soon as you can and installed back onto your vehicle. This way, the 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. 423
