All wheels have zero offset.
Lug Nut Torquing
Trailer wheels must carry much higher loads per wheel
than passenger car or truck wheels. Each wheel may
carry 1000 pounds and higher. Furthermore, wheels on
tandem axle trailers do not steer, and are subjected to
very high side load stress whenever the trailer makes
a tight turn. When going around corners, especially on
slow, tight turns, the wheels are subject to very strong
side loads. Although the materials and manufacturing
methods are maximized for this kind of service, these
extra loads can cause stress, which can result in
exing and loosening of wheel nuts.
Before each trip and any time a wheel is replaced, be
sure to tighten the wheel nuts, following the lug-pattern
sequence shown below. If the wheel was replaced,
check the torque every 10, 25, and 50 miles.

If you notice wheel wobbling, or hear a rattling sound
coming from a wheel, especially at low speeds, a
wheel lug nut may have come loose. This problem is
usually caused by improper tightening, or by faulty or
damaged lug bolt threads.
If suspicious of a loose lug nut, safely stop the vehicle
as soon as possible. Put up warning devices. Remove
the lug caps and check the tightness of all the lug nuts.
Tighten all lug nuts to the specied torque, using a
torque wrench. If stud threads are damaged or faulty,
get professional service help.
NOTE
Use a torque wrench to tighten lug nuts.
Tightening by hand or with an impact wrench is not
recommended. Torque Aluminum Wheels to 110 ft.
lbs and Steel Wheels to 100 ft. lbs.
Spare Tire Carrier
The spare tire for Airstreams is stored under the front
of the trailer. The front handle of the tire carrier is a 1
in. tube protruding out from under the front A-frame
on the curbside. It is secured by a bracket and bolt
along the inside of the A-frame rail. Removing the bolts
allows the front on the tire carrier to be lowered and the
spare tire to be removed.
WARNING
The spare tire carrier is designed to carry an
undamaged tire and rim assembly of the type and
size specied for the trailer. Never place a severely
damaged wheel assembly with a damaged partial
tire, or a rim only, in the carrier.

NOTE
Never allow heat to be applied to the axle tube
because the rubber providing the spring torsion
action will be severely damaged.
