PURPOSE:To house both emergency and normal use tires by utilizing difference in the rim between the two tires so that a ring section of a spacer for fixing spare tires can be held inside the rim of the normal use tire. CONSTITUTION:The thickness t1 of an emergency tire 17 is less than the thickness t2 of a normal tire while the rim diameter D1 of the emergency tire 17 is larger than the rim diameter D2 of the tire 20. Therefore, when suspending the normal tire with a hanger, a spacer 19 which is made in a double step with a circular flange 24 is placed on the normal tire 20 with the flange 24 upward. The flange 24 contacts the rim lug 32 thereof while a ring 23 is held inside a rim 31. When suspending the emergency tire, the spacer 19 is placed on the emergency tire 17 with the flange downward. The total H1 of the thicknesses of the spacer 19 and the tire 17 equals the thickness of the normal use tire thereby permitting one hanger to suspened the tires each varied in size. |
