CAUTION
Alawys use an accurate gauge when checking
tire pressure. An inaccurate gauge can be in
error as much as 2 or 3 pounds, which is ap-
proximately 10 per cent of the recommended
tire pressure.
Make sure the valve caps are tight, after
checking tire pressure.

TIRE ROTATION
Rotating tires at intervals of 3,000 miles is the
only known method of controlling certain types
of tire wear. Tire life (Fig. 9) can be increased
as much as 25 per cent by regularly rotating
the tires, including the spare.

CAPTIVE—AIR SAFETY TIRE (Fig. 10)
NOTE:
The captive-air safety tire is used on the
three seat Town and Country wagon only.
The captive-air safety tire is actually a tire
within a tire, forming two air chambers. The
inner chamber is known as the shield and the
outer chamber the tire. Basically, the shield
and tire form two independent air chambers,
one enclosing the other. If the outer chamber
is collapsed, the inner chamber remains in-
flated and intact.
IMPORTANT: When outer chamber of tire is
deflated, it is recommended that continued driv-

ing speed should not exceed 40 M.P.H. until
tire has been repaired.

RIM PREPARATION
Scrape off all rust flakes and clean rim flanges
and bead seats with a wire brush or steel wool.
To prevent leakage, badly rusted pitted rims
should be heavily coated with vulcanizing ce-
ment to fill the rust cavities. Install tubeless
tire valve.
16.
INSTALLING THE SAFETY SHIELD
With tire flat on the floor, insert the safety
shield into tire and set the molded channel
shaped edge over the top tire bead. Smooth out
wrinkles and distribute uniformly by working
and rubbing the bead channels by hand until
the shield wing is set firmly and smoothly
against the tire bead. Turn the tire over and
repeat the same procedure on the second bead.
17.
LUBRICATION
Apply a liberal coating of soapy water (made
of high grade soap flakes or vegetable oil soap
and water to consistency of paste) to the outer
bead surfaces (flange and base) of the safety
shield and also to the corresponding surface
of rim.
CAUTION
Do not use detergents or any substance that
might be harmful or injurious to rubber or
rim surface. Use care not to let soap get be-
tween the tire bead and safety shield.
