driving habits, etc. To obtain maxi­
mum tire life you should inspect
and rotate your tires regularly.
Many car
and tire dealers will per­
form a free tire inspection
and
assist you in identifying uneven
or abnormal tire wear which is
usually the result of incorrect infla­
tion pressure, lack
of regular rota­
tion, improper wheel alignment,
out-of-1?alance, or poor driving
habits.
Bias
and bias-'belted tires shOUld
be rotated at least every 7,500
miles. Radial tires should be ro­
tated at least at the first 7,500 miles
and then at least at 15,000 mile in­
tervals thereafter or whenever un­
even tire wear is noticed.
Alignment and Balance
Proper front-end alignment mini­

To minimize
tire wear, your front-end suspen­

brakes be inspected for wear when­
ever the tires are rotated.
spected regularly.
See the Main~e­
nance Schedule folder for more m­
formation. Some ball-joints have
built-in wear indicators and some
movement in the joints
is normal.
Improper front -end alignment will
.
not cause vibration. Improper toe
alignment
may cause your. fro~t
tires to drag at an angle resultmg m
excessive wear. Improper camber
alignment may cause your front
tires to wear more
on one side than
on the other and can cause the
vehicle to
"pull" to the left or right.
Proper tire balancing provides
the best riding comfort and helps
to minimize tire tread wear.
Out-of­
balance tires can cause annoying
vehicle vibration and irregular tire
wear such
as cupping, fiat spots,
etc.

Your car receives its power from
a mixture of gasoline and air. The
air
is taken in to the system through
the air cleaner
so it's important to
replace the air cleaner at required
intervals. A dirty air cleaner re­
duces engine efficiency.
Properly Tuned Engine
Overall tuning (a check on tim­
ing, spark plugs, emission control
devices, etc.) can improve your
car's gas mileage. You just can't
expect an
"out-of-tune" engine to
give you good gas mileage and
cleaner air.
Excess Weight
Fuel economy is related to the
work the engine must do. The
heavier the load, the more power it
takes. Keep excess weight to a
minimum by removing any per­
sonal effects or luggage from the
car or trunk when they are not
needed.
Tire Inflation
Underinfiation not only causes
needless wear of the tires, but can
also waste gasoline. It's a good
idea to check tire pressures
regularly.
Wheel Alignment
Incorrect "toe in" or "toe out" can
have the effect
of dragging your
front tires sideways and may cause
premature tire wear.
It takes power
to carry this extra load and that
takes gas from your tank.
Catalytic Converter
The catalytic converter IS an
emission control device added to
5-22
the exhaust system to reduce hy­
drocarbon and carbon monoxide
pollutants from the exhaust gas
stream.
The converter contains
beads which are coated with a cata­
lytic material containing platinum
and palladium.
Use of the catalytic converter
has the advantage of allowing the
engine to be re-tuned for improved
fuel economy and driveability.
The catalytic converter requires
the use
of unleaded fuel only.
Unleaded gasoline is used to re­
duce combustion chamber deposits,
corrosion and
to prevent lead con­
tamination of the catalyst that
would render it ineffective.
The use
of leaded fuel will cause the cata­
lytic converter to
become ineffec­
tive as an emission control device.
