PURPOSE:To shield a spare tire from air, prevent the oxidizing deterioration of a rubber material from generating, and recycle the spare tire by shrink- packing the whole body of a tire to be used as spare tire only, which is installed in a wheel by a rim, with a resin film. CONSTITUTION:A tire 1, to be used as space tire only, is installed in a wheel 2 by a rim 2a of the wheel 2, and pressurized air is filled in the tire 1. The whole body of the tire 1 and wheel 2 of a spare tire wheel 10 is shrink-packed by a shrinkable resin film 3, and the resin film 3 is tightly joined to the surface, and the spare tire wheel 10 is put under a condition in which a contact with air is totally shut out. Since an inert gas is filled in the tire 1 instead of air, the rubber material is hard to oxidize by air, and the storage for a long period of time becomes possible. For this reason, if this spare tire wheel 10 is never used until the time to scrap the vehicle, it can be recycled to a new vehicle without problems. Whether the spare tire wheel has been used or not can be easily judged by the presence/absence of the resin film, and the management of the recycling becomes easier. |
