  13. Caution: Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after time. The wheel could come off and cause an accident. When changing a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire .

    Remove any rust or dirt from the wheel bolts, mounting surfaces and spare wheel.

    Caution: Never use oil or grease on bolts or nuts because the nuts might come loose. The vehicle's wheel could fall off, causing a crash.

  14. Put the wheel nuts back on with the rounded end of the nuts toward the wheel after mounting the spare tire.
  15. Tighten each wheel nut by hand. Then use the wheel wrench to tighten the nuts until the wheel is held against the hub.

  17. Caution: Incorrect or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to a crash. If you have to replace them, be sure to get new original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications for wheel nut torque specification.

    Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications for the wheel nut torque specification.

When you reinstall the regular wheel and tire, you must also reinstall either the center cap, bolt-on hub cap, or plastic nut caps, depending on what your vehicle has.

    • For center caps, line up the tab on the center cap with the slot on the wheel. The cap only goes on one way. Place the cap on the wheel and press until it snaps into place.
    • For bolt-on hub caps or plastic nut caps, line up the nut caps with the wheel nuts and tighten them clockwise by had to get them started. Continue tightening with the wheel wrench until snug.
