Maintenance OCTANE RECOMMENDATIONS Regular unleaded gasoline with a pump (R+M)/2 octane rating of 87 is recommended. Some stations offer fuels posted as ЉRegularЉ with an (R+M)/2 METHOD octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended. Premium fuel will provide improved performance and is recommended for severe duty usage such as trailer tow. Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily under most driving conditions while you are using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage. 87 WHEELS AND TIRES Tires Wheels TIRE ROTATION Because your vehicle's tires perform different jobs, they often wear differently. To make sure your tires wear evenly and last longer, have them rotated. Note: The F-150 Raptor requires tire rotations every 5,000 miles (8,000 km). If you notice that the tires wear unevenly, have them checked. LT315/70R17 BSW tires SVT-Signature style, 17 in x 8.5 in aluminum 6-spoke wheels SPARE TIRE AND WHEEL Your vehicle is equipped with an LT315/70R17 spare tire.
