TAREFUL application Of tires is
quite as necessary to good serv-
ice as the selection Of correct
size for load, or rims being Of right
design and regular in measurement
Before applying tires. remove rust
and all other foreign matter from
rims. The danger of pinching inner
tubes can be reduced to a minimum
by busting soapstone or powdered
mica on the rims so that the tire beads
will slip easily into the correct posi-
ton.
Initiate inner tubes just enough to
round them out before placing them
inside Of cases. Do not use tubes Of
the wrong size and be sure that the
valves are equipped with spreaders
adapted TO the particular type Of
cases used, for instance, Clincher.
Quick Detachable Clincher. or Straight
Side. Valves in Firestone tubes are
equipped with universal spreader and
therefore suitable for use in all three
types. Dust the inside Of the case
and the inner tube with powdered
mica or tale. This will reduce friction
and prevent adhesion Of tube to case
after being heated in service.
When the tires have been removed
for any reason. it is a good plan,
when reapplying. to reverse them,
that is. 10 place the worn sides OF the
tires toward the car It is not gener-
ally known, though II is a fact, that
almost all the side wear to a tire
occurs on the side from the car This
is due to road construction, rut wear
curb scraping. etc.
The life OF a tire may be prolonged
to such an extent that a great deal
more mileage may be secured by
turning the tires about occasionally
to secure even wear upon both sides.
The use Of straight side cases on
clincher rims is discouraged II best
results are TO be expected from
straight side tires they should be used
only on straight side rims which are
slightly wider at the base and per-
init of the necessary spread between
cables. II. for some special reason. it
is desired to use straight side tires on

Some tire users do not realize the
Importance Of using flaps. and others.
due TO Indifference. or carelessness,

Users OF quick detachable rims hav-
ing reversible rings should be very
careful that rings on both sides are
suitable 10 accommodate the type OF
tire applied. l. e., when using clincher
tires, both rings should be in posi-
ton to properly engage beads and II
straight side tires are to be used. both
rings should be in position 10 fit the
straight beads or straight sides OF
this type.
Tire Flaps and Their Importance.
II is not customary to use flaps
with clincher tires of small size, not
because it is unnecessary, but be
and stretching the tire on the rim so
that IL will fit properly. The beads
OF this type Of tire are stretchable
and are made approximately 1 inch
ing to cause the tire 10 fit snugly
to rim after applied.
Several years ago II was a prac-
tice to use rim strips, a strip of fab
ric stretched tightly on rim. These
strips caused the beads to fit very
snugly to clinches Of rim and pro-
tected the tube from rust and other
damage Flaps should be used, how
ever. in clincher tires in sizes above
4 inch. unless clips or spreaders are
used to hold the beads tightly in
clinches Of rim so that inner tubes
beads of quick detachable clincher
cases and cables OF straight side cases
are non stretchable and are. there

meter Of rim Flaps should be used
in all sizes Of quick detachable elm

rienced with the inner tubes.
Filters Poor Substitute for Air.
Junctures used to mean a lot OF
trouble for tire users. but the refine
ments in rims now make quick
changes possible and this bugaboO no
longer worries the average driver.
So called filters" intended to elimi-
nate the inconvenience Of punctures,

rlous makes, owing TO the difference
in the design. contour and size OF
tires. Some filler manufacturers rec
ommend that. after being in service
for short time. more filler be added
to take care of the stretching and
other changes in tires.
