Vehicle Care "Storing a Flat or Spare Tire and Tools" under Tire Changing on page 10‑66. 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 alright 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 the vehicle has four-wheel drive and a different size spare tire is installed, do not drive in four-wheel drive until the flat tire is repaired and/or replaced. The vehicle could be damaged and the repairs would not be covered by the warranty. Never use four-wheel drive when a different size spare tire is installed on the 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. 10-81 Jump Starting For more information about the vehicle battery, see Battery on page 10‑29.
