10-72 Vehicle Care Lightly coat the center of the wheel hub with wheel bearing grease after a wheel change or tire rotation to prevent corrosion or rust build-up. Do not get grease on the flat wheel mounting surface or on the wheel nuts or bolts. Reset the Tire Pressure Monitor System (TPMS), if the vehicle has one. See Tire Pressure Monitor Operation on page 10‑66. Check that the spare tire, if the vehicle has one, is stored properly. Push, pull, and then try to rotate or turn the tire. If it moves, tighten the cable. See "Storing a Flat or Spare Tire and Tools" underTire Changing on page 10‑81. Check that all wheel nuts are properly tightened. See "Wheel Nut Torque" under Capacities and Specifications on page 12‑2. Dual Tire Rotation When the vehicle is new, or whenever a wheel, wheel bolt, or wheel nut is replaced, check the wheel nut torque after 160, 1 600, and 10 000 km (100, 1,000, and 6,000 mi) of driving. For proper torque and wheel nut tightening information, see "Removing the Spare Tire and Tools" under Tire Changing on page 10‑81. The outer tire on a dual wheel setup generally wears faster than the inner tire. Tires last longer and wear more evenly if they are rotated. See Tire Inspection on page 10‑69 and Tire Rotation on page 10‑70. Also see Scheduled Maintenance on page 11‑2. { WARNING 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, a cloth or a paper towel can be used; however, use a scraper or wire brush later to remove all rust or dirt.
