Application of Tires

Careful application Of tires is quite
rs necessary to good service as the
selection of correct size for load, or
rims of right design and regular in
measurement.
Before applying tires, remove rust
and all other foreign matter from rims.
The danger Of pinehing inner tubes can
be reduced to minimum by dnsting
soapstone or powdered mica on the rims
so that the tire beads viii slip easily
into the correct position.
Initiate inner tubes Just enough to
round them out before placing them in
side Of the eases. Do not use tubes of
the wrong size. Be sure that the valves
are equipped with speaders adapted to
the particular type of cases used, for
instance, Clincher, Quick Detachable
Clineher, or Straight Side. Valves in
Firestone tubes are equipped with uni
versal spreader and therefore suitable
for use in all three types. Dust the in
side of the case and the inner tube
with powdered mica or tale. This win
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 good plan, when
reapplying, to reverse them, that is, to
place the worn sides Of the tires to-
ward the car. It is not generally known,
though it is fact, that almost all the
side wear to a tire occurs on the side
from the car. This is due to road con-
struction, rut wear, curb scraping, etc.
The life of tire may be prolonged
to such an extent that 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. If best
results are to expected from Straight
Side tires they should be used only on
Straight Side rims which are elghtIy
wider at the base and permit Of the
necessary spread between beads. If,
for some special reason, it is desired to
use Straight Side tires on Clincher
rims, the rims should always be equip
ped with filler beads.
Some tire users do not realize the i'm
portanee of using flaps, and others, due
10 indifference, or carelessness, place
the tubes above the flaps.
Users of Quick Detachable Rims
having reversible rings should be very
careful that rings on both sides are
suitable TO accommodate the type of
tire applied, i. O., when using Clineher
tires, both rings should be in position
properly to engage beads and if
Straight Side tires are to be used, both
rings should be in position to fit the
straight beads or straight sides Of this
type.
Tire Flaps and Their Importance.
1t is not customary to use flaps with
Ciincher tires Of small size, not because
1t is unnecessary, but because of the
difficulty in using a flap and stretching
the tire on the rim so that it win fit
properly. The beads of this type Of
tire are stretehable and are made ap-
proximately 1 inch less in diameter
than rim, the object being to cause the
tire to fit snugly to rim after applied.
Several years ago it was n practice
to use rim strips, strip of fabric
stretched tightly on rim. These strips
caused the beads to fit very snugly tc
elinehes of rim and protected the tube
from rust and other damage. Flaps
should be used however, in clincher
tires in sizes above 4 inches, unless
clips or spreaders are used to hold the
beads tightly in clinches of rim so that
inner tubes win not be pinched or
damaged, The beads of Quick Detach-
able Clincher cases and cables Of
Straight Side cases are non-stretehable
and are, therefore, made to the APP
proximate diameter Of rim. Flaps
should be used in all sizes Of Quick
Detachable Clincher and Straight Side
cases, otherwise much difficulty will be
experienced with the inner tubes.
