9-62 Vehicle Service and Care Removing the Flat Tire and Installing the Spare Tire 1. If your vehicle has wheel covers, remove the cover. Do not try to put a wheel cover on your compact spare tire. It will not fit. Store the wheel cover in the trunk until you have the flat tire repaired or replaced. 5. The jack and tools are stored below the spare tire. 6. The tools you will be using include the jack (A), wheel wrench (B) and jack handle (C). Notice: Wheel covers will not fit on your vehicle's compact spare. If you try to put a wheel cover on the compact spare, the cover or the spare could be damaged. 2. If your vehicle has wheel bolt caps, remove the caps. Store the caps with the wheel cover. 3. Use the wheel wrench to loosen all the wheel bolts. Do not remove them yet.
