automobile tires last year. OF
This vast expenditure, experts
figure SI9J, 1000, 900 was squandered
by auto drivers through careless
ness and Ignorance in the use
and care of tires. The FtrestOne
Tire d Rubber company believes
much of this unnecessary tire eI-
pense can be eliminated through
education and that Is the purpose
of these articles. which were pre-
pared by experts and offer only
simple, practical suggestions
he car owner of today is fast
coming TO the realization that
L mileage he gets from his tires
depends upon the treatment they are
given. Mileage is built into tires at
the factory by scientific methods. The
user can get every inch Of that in
built mileage out OF the equipment
by the proper care and use Of it.
The motorist ordinarily places so
much confidence in tire equipment,
nrobably because OF its rapid de-
velopment and wonderful perform
ances. that il does not receive the
fnspection and attention considered
necessary for the car Hence the loss
to the average car owner OF 80 cents
on every dollar spent for tires, ana
the opportunity for these articles
which are designed to enable every
car owner, who reads them, 70 save
his share of the S105,000,000 wasted
on tires each year
It has been aptly said that the
pneumatic tire is Of the most para
doxical construction in the entire
field Of automobile engineering II
must be very resilient yet withstand
punishment worthy Of armor plate
Two tender substances. rubber and
cotton fabric must be so blended ana
built up that they will resist the air
automobile and its load without the
thrust of the motor. the transverse
strains on turns and the blows
of thousands Of obstacles. And
upon the successful construction Of
! the tire has depended the entire sue
cess OF the automobile.
While the selection OF the right
type and size, correct application and
proper treatment Of tires are an
necessary to obtain the best results,
the simple matter OF Initiation Is
probably the most important point
it's abuse is the principal cause OF
tire wastage.
What Proper Initiation Means.
The judicious use OF air VIII go a
long way toward giving the tire user
the maximum mileage Because the
resiliency and long wearing quail
ties Of a tire depend almost as much
upon proper initiation as they do up
on the rubber and fabric Too much
air will cause excessive vibration,
traction slippage and loss OF power;
too little will bring on excess frlc-
ton between various parts OF the
tire and cause them to break up.
There is a very definite relation
between the air pressure within the
tires and the load on them. Inc
heavier weight or reduced air pres
sure causes more DETECTION OF the
tires, giving wider tread on the
ground, and increases the action on
the sidewalks. This adds to the COM
fort OF the ride as more OF the ROAD
vibration is absorbed by the tires:
But when soft. the tire runs against
q wave in the tread rubber, which
from excessive stretching and heat
ing pulls %Way and separates from
the carcass or body. The side walls
bend back and forth, back and forth,

when a piece OF wire IS beat PACK

Der cement or adhesiveness between

particularly hard bump. a loud ex-
plosion rends the air and It IS time
to put on a new casing
Flat Tires Demand Attention

Demountable and quick detachable

the tires attention when needed

to the differential OF the car.
Expansion caused by hot weather

materially affect the tire, as the air
pressure within Is not increased 10
any appreciable degree. New tires
stretch slightly when first used and
inner tubes are slightly permeable
to nitrogen so that occasional infla-

filling the tires with a fresh supply
