Storing a Flat Tire (ZR-1 Rear Tires)
A ZR-1 rear tire will not fit in the tray, so you must put
it on the floor of the rear area. Put the flat tire in the
storage bag provided. Place the tire on the rear area
floor.
Use the luggage straps to hold the tire in place. Loosen
the straps, then attach each end of the longer strap to the
rear cargo hooks.
Attach the other strap to the hook behind the console.
