The valve stem is the heavy point of the tube and should always be
placed at this mark.
All tires
and
tubes vary somewhat in their individual amounts of
off-balance and are, therefore, matched
at
the
factory
to counter-
balance
each
other.
Due to irregularities in tread wear caused by sudden brake applications,
misalignment, low inflation pressures, tube or tire repairs,
etc.,
a tire
and tube assembly can lose its original balance.
If a disturbance is felt in the steering wheel due to the action
of
the
front wheels, or if pounding, tramping, or shimmying is experienced
while driving, one of the first items to check is the static balance of
tires and wheels.

TIRE SWITCHING-Switching tires from one
position to
another
on the car usually prolongs
tire life.
If you have four good tires, you might
consider switching at regular intervals by cross-
changing them from right front
to
left rear
and
left front to right rear. With five good tires, how-
ever, tire
switching

spare. By having your tires switched every 4,000
miles and using the spare, you can drive 20,000
miles and only put 16,000 miles wear on each of the tires.
SAVING TIRES WHEN YOU DRIVE-Maximum tire life can be
secured by careful attention to driving habits and a few
essential
details of service. We have listed below the most important points to
help you secure this maximum.
1. Keep tires properly inflated at all
times.
2. Avoid spinning wheels when star'ing.
3. Avoid sudden stops.
4. Turn
corner~
at moderate speeds.
5.
Steer around bumps, ruts, or minor obstructions in the road
.
6. Keep out of car tracks.
7. Do not bump or scrape the curb.
8. Keep the front wheels in proper
alignment.
(See page 28.)
9. Keep brakes adjusted. Uneven brake adjustment causes uneven
tire wear.
10. Interchange tires every 4,000 miles. (See above.)
TO CLEAN WHITE SIDEWALLS-Use soap, warm water
and
stiff
brush to remove road grime
and
curb dirt from white sidewall
tires.
