If your vehicle has wire wheel covers, remove them as follows: Using the flat end of the key wrench handle, between the wire wheel cover and the center cap, pry off the center cap. Use the wire wheel key wrench to remove the wheel cover. Remove the theft-deterrent nut, by placing the key end of the wire wheel key wrench over the nut and turning it to the left. Pull off the wire wheel cover. Note: When replacing the wheel cover, carefully line up the tire valve stem and the notch in the wheel cover.
