yellowblue NOTICE: Never remove or store a tire from/to a storage position under the vehicle while the vehicle is supported by a jack. Always tighten the tire fully against the underside of the vehicle when storing it. Insert the chisel end of the wheel wrench, on an angle, into the hole in the rear bumper. This is the jack cover for the extended cab. The cover for the regular cab is similar. To remove it, turn the plastic wing nut counterclockwise. Remove the jack cover. Turn the wing nut counterclockwise and remove the wheel blocks, jack and wheel wrench. Your spare tire is stored underneath the rear of your vehicle.
