Tire Rei
CAUTION.
Different types of tires, such as bias, bias
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
Lateral runout (A) and radial runout (B)
Steel wheel .. Less than
Aluminum wheel
. Less than
1 0 mm (0.039 in)
0 5 mm (0 020 in)
Difference between right and
left lateral runout.
