belted and radial
tires, must not be mixed
under any circumstances
When replacing
a tire, use a tire of the same
size
Do not use tires and wheels other than those
recommended
Do not mix tires of different brands or tread
patterns
When replacing standard
tires with those tires
of an oprional recommended size and of
different diameter, the speedometer must be
recalibrated
To install wheel, tighten wheel nuts in criss-
cross fashion
SMA737A
To install an aluminum wheel, proceed as
(1) Snugly tighten all nuts after the wheel is
follows
positioned
icement
(2) Slightly pull the wheel back to properly
align the nuts with bolt holes in the wheel,
and tighten the nuts
as much as possible
with
your fingers
Align nuts with bolt haler in wheel and evenly tighten nuts each one a little at a time
SMAOll
(3) Tighten wheel nuts evenly with a wheel wrench
Be sure to check the wheel nuts for tightness, after
the aluminum wheel
has been run for the first
1,000 km (600 miles) (also in case of repairing
flat tires, tire rotation, etc ).
Replace if necessary.

Tire Repair
CAUTION
When replacing tire, take extra care not to damage
tire bead, rim-flange and bead seat.
Install tire, noting the following items
a. Install valve core and inflate to proper pressure.
Check
the locating rings of the tire to be sure
they show around the rim flanges on both sides
b. Check valves for leakage after inflating tires.
c.
Be sure to tighten valve caps firmly by hand
WARNING:
When, while tire
is being inflated, bead snaps
over safety hump,
it might break. Thus, to avoid
serious personal
injury, never stand over tire when
inflating it Never inflate to a pressure greater than
40 psi (275 kPa). If beads fail to seat at that
pressure, deflate
the tire, lubricate it again, and
then reinflate it. If the tire is overinflated, the
bead might break, possibly resulting
in serious
personal inlury.
Wheel Inspection
Check wheel rim (expecially rim flange and
bead
seat) for rust, distortion, cracks or other
damage Examine wheel rim for
lateral and radial runout,
using dial gauge

Spare Til
(2) To ensure complete emptying of the canister,
hold the canister in position for one minute
after sound stops
If temperature is below -10°C (14OF), the
canister must be warmed on
the windshield
defroster for five to ten minutes to provide
tire
inflation
b. In cold weather, the tire may not look fully
.inflated Therefore, drive slowly for the
first
mile, as the tire temperature rises the pressure
will mcrease.

Using Air Compressor
(1) Remove the valve cap from the spare tire and
securely connect the air pump hose in
its place
(2) Connect the power cord plug of the air pump
to the cigarette lighter socket The spare
tire
may be inflated to the recommended pressure
28 psi (200 kPa) in about 6 minutes Adjust
the
tire pressure per the tire placard with tire
pressure gauge
If the air pump operation is slow, run the engine
while the air pump is operating In this case,
remove jack with
the spare tire attached to the
axle.
WARNING:
0
0
Do not run the engine in closed space or with
the car being jacked up
Do not touch the air pump with the bare hands
while
it is operating for it may become quite
hot.
(3) Disconnect the power cord plug from socket
Check the
tire for air leakage, and then
securely install and tighten the valve cap
5 Lower car and fully tighten wheel nuts
Do not
install the wheel cover on the spare tire
DEFLATION
1 Deflate tire by depressing button on tire
inflation valve or by removing valve core
