Removing the Flat Tire and Installing the Spare Tire Your vehicle may have aluminum wheels. If so, you will see exposed stainless steel wheel nuts. Use the wheel wrench to loosen all the wheel nuts. Do not remove them yet. Or, your vehicle may have steel wheel covers. To remove the steel wheel covers and wheel nut caps, loosen the plastic nut caps with the wheel wrench in a counterclockwise direction. If needed, you can finish loosening them with your fingers. The plastic nut caps will not come off. Use the flat end of the wheel wrench and pry along the edge of the cover until it comes off. The edge of the wheel cover could be sharp, so do not try to remove it with your bare hands. Do not drop the cover or lay it face down, as it could become scratched or damaged. Store the wheel cover in the trunk until the flat tire is repaired or replaced. 5-100
