HOW TO KEEP DOWN
YOUR TIRE BILL
Mileage Can Be Doubled by
Proper Attention to Pressure
and Small Abrasions.

II time. expense and trouble are to be
at ali considered there 10 no more I'm
portant question relative TO the running
Of . motor car than the are Of the tire
casing. and II may be said right at the
start that a. . general thing there 10
no part OF the machine which receives
as little proportionats attention. says
Motor Age. II has been estimated that
the expense Of upkeep Of the machine
10 divided into three equal parts. namely.
fuel. including gasolene and oil. tires
the other parts Of tho machine put
together. BY this 10 meant that
each Of these three divisions. II
they may 10 b termed, IL responsible
for one-third OF the actual expenses Of
running the car. II must be remem
bered that tires cost one-third the total
Expense. providing they are given proper
care. II they are neglected their cost
will run above this one-third figure. The
motorist a. q rule worries q great deal
as to o many miles ne can get put of
a gallon Of gasolene. but when the hg-
ures hero presented are considered II
would seem that the owner Of the ma
chine would be money In II he would. In
addition to counting the miles per gal
lon. give the care and repair of the
casing a little more attention.
One OF the big items In operation o:
the modern tire factory Is that'of max
ing replacements-giving q new tire In
the place OF a worn out or ruined cas-
ing which when purchased was guaran-
iced for a given number Of miles. Frank
II. Carroll. Los Angeles. Cal. manager
OF the Goodrich Rubber Company. stated
recently that fully as per cent. Of the tires
taken back 10 him as defective" In some
particular are not defective at all. but
Rave simply been subjected to some sort
OF abuse or misuse. Many motorists
purchase castings with the feeling that
II rhe tires do not run " the full guar
antee Of $500 or 5000 miles. regardless
Of the treatment given them. replace
ments or mileage can be secured from
the tire company. They do not nsure
that with proper treatmen; those same
castings will a. q rule make from 5000
TO 10000 miles n sometimes more.
thereby giving the motorist several thou
sand more miles han he would receive
otherwise, even with repiacements. not
to mention the assurance of having q
set of good tires under the car.
OF the many ways In which the casing
Is subjected to abuse possibly the two
most common are overlooking and under
imitation. the results Of which are iden-
teal. That these m!suses have been
given a tire is indicated either by n
wavy condition OF the tread. showing
that the adhesive friction between the
layers Of the fabric has become over
heated through this cause. or by bad
cuts along the side walls or along the
rim. A rim cut tire In ar easy victim
to biowouts. CnIuestionsSly there are
moro tires ruined on account OF under
imitation than from any other one cause,
This particular cause OF trouble will
not only result In a ruined casing. but
IL also responsible for tube troubles
Common sense will cell one that II the
tire which Is run soft II indented by a
curhinG or stone until tho tread bumps
against the beading or rim the soft
inner tube within Il Is bound to suffer.
Keep the tires pumped TO the pressure
recommended by the manufactures.
Sometimes . tire may be run for
weeks after the fabric has been broker
before he blowout occurs, The blowout
may occur while the car Il standing In
the garage or on the street. Sometimes
a few OF the plies Of abric were broken.
this opening sufficiently 20 pinch the
inner tube. allowing the tire to debate
gradually. Another cause Of trouble
similar TO the stone bruise comes
through rough handling Of the car going
into the curling. a sharp corner or the
curblng coming IN contact with the side
wall Of the tire causes an injury which
may not be noticed at the time. but
which NO weakens the layers Of the
fabric that nj a later date serious trouble
results.
Another common trouble which eats
up perfectly good tires Is misalignment.
| wher- the wheels are not correctly lined
up. In n case Of this kind the tires are
continually skidd.ng, and II Ia this con-
stant grinding away of the tread hat
causes the fabric TO show through and
for the motorist. a. a rule. to condemn
the tire as well AZ the tire maker.
Faulty alignment usually occurs In the
front wheels, and may be caused by .
sharp bump OF the wheels against the
curbing or other obstacle. Instances
have presented themselves where. OF
account Of faulty alignment. a tire has
been worn 70 badly a. to be ruined
within a distance Of nifty miles.
The act of lining up the wheels Is NOT
a dificult M II the motortct has thu
knack. but II he does not know how
the car should be taken to some expert
enced repairman and IN work done
right. As q rule when the front tire
Is affected both tires win show damag-
ing results. although very often only
