Removing the Flat Tire and Installing the Spare Tire (STS Only) 1. If your vehicle has wheel covers, use the flat end of the wheel wrench to remove the covers. Turn the wheel wrench clockwise to gently pry off the wheel cover. Be careful not to scratch the aluminum wheel edge and do not try to remove the wheel cover with your hands. 2. Loosen the wheel nuts, but do not remove them yet, using the wheel wrench. Turn the handle about 180 degrees, then flip the handle back to the starting position. This avoids taking the wrench off the lug nut for each turn. 5-86
