A winch mounted under the rear floor is used to lower and raise the spare tire.
The winch has a nut sticking up through the floor under the center rear lounge
on the rear lounge model accessed by opening the rear cargo doors. The nut
is located inside the roadside bed on the twin bed model and is accessed by
opening the bed storage door. To remove the spare tire, use the ratchet and a
19MM or 22MM deep well socket located in the tire replacement bag under the
passenger side compartment floor to turn the winch nut counter clock wise.
Place blocks under the tire before it reaches the ground to block the tire up and
remove the weight from the yoke, then slide the yoke through the rim, and slide
the tire from under the motorhome.
Wheel lug pins
Wheel lug pins
Winch Tire Yoke
To store a spare tire reverse the removal instructions. The winch tire yoke has
two pins that align with the wheel rim lug holes. The yoke pins must be placed
in the lug holes to prevent the wheel assembly from sliding against the cable
during transit and possibly cutting it. Be sure wheel is turned on the correct
side so pins will fully engage the lug holes. The side of the rim that goes against
the hub goes against the floor.
nOTiCE:
Spare tire carrier winch is designed for hand operation only. Do
not use impact type power tools to drive this device.
Warning:
Defective spare tire equipment or an improperly
stored spare tire could damage your equipment and/or cause serious,
possible fatal injuries to people inside your motorhome, other motorists
and pedestrians. The yoke pins must be inserted into the spare tire lug
holes while wheel is in the store position during travel. The cable and
support system must be free from defects and in good working order.
The complete system should be checked before each trip and every 1000
miles during a trip for any signs of wear or possible failure. Please contact
your dealer or Airstream Customer Service if you have any questions on
