tires.
Sus-
tained
speed above
75 mph are not
recommended when the 4 pounds per

adjustment
would require
pressures
greater
than the maximums
stated in the
chart.
3.
Cold
tire inflation pressure: After
ve-
hicle has
been
inoperative for 3 hours
or more,
and
driven less than 1
mile.
Hot tire inflation pressure: After
ve-
hicle has been driven 10 miles or more
at 60 - 70 miles
per
hour.
4. Vehicles with luggage racks
do
not
have a vehicle load limit greater than
specified.
5. When towing trailers, the allowable
passenger cargo load must
be
reduced
by
an amount
equal
to the trailer
tongue load
on the trailer hitch.

Tread
Wear Indicators
-
The original
equipment tires
on
your Oldsmobile
in-
corporate built-in tread wear indicators to
assist
you
in detennining when your tires
have been worn to the point of needing
replacement. These indicators are molded
into the bottom
of
the tread grooves and
will
appear as
'h inch wide bands when
tire tread depth
becomes
1/
16
of
an inch.
When the indicators
appear
in two or more
adjacent grooves, tire replacement due to
tread wear is recommended.
46
Optional Tires
-
Only those tires of the
size shown on
the
adjacent
table are rec-
ommended for use on
Oldsmobiles. Use
of any other size of
tire may
seriously
affect ride, handling, ground clearance,
tire clearances, and
speedometer
calibra-
tion. To
achieve best all around
vehicle
handling performance, fiberglass belted
tires, radial ply tires,
and
bias ply tires
should
not be mixed on the
same
car.

Tire Rotation Infonnation - To
equalize
wear it is recommended that the four road
tires be rotated
every 6,000
miles
in
ac-
cordance
with diagram. It is not necessary
to rotate the spare.
Upon
rotation, tire
pressures must be
adjusted (front
and rear)
in
accordance
with the recommendations
in the tire inflation pressure table.
