CORD TIRES GAINING
FAVOR WITH PUBLIC
Year. Has Revealed Advance Toward
Perfection of Scientifically
Balanced Tire.


Five features stand out prominently
as achievements IN the tire industry dur
ing the past twelve-month- They are
features Of vital concern aiike TO all
They are:
% A considerable increase In the use
of cord tires.
CO A steady advance toward the per-
lection Of the scientifically balanced tire.
ca A slightly decreased demand for col-
ored treads
% A big advance In the use Of nom
0 An increase In the use Of straight
side casings.
It is predicted that cord tires win be
used on cars selling for as low as 1850
In the near future. This. despite the fact
that the constructions Of the cord tire
makes itsmore expensive to. produce and
more expensive to the ultimate consumer.
steady Advances.
Nevertheless the cord tire has been
making steady advances during the year.
and the list Of car manufacturers who
are using It as standard equipment IL
lengthening. Also. nearly every tire
maker Of prominence now 10 experiment
ing with the cord tire: some already have
them on the market In q small way;
others are preparing to put them on the
market soon after the new year.
There are two schools Of cord tire
makers. These make what are known a.
the cable type and the thread type. The
former Ii represented by Goodrich and In
these tires the carcass IN made up Of
two layers Of very heavy cord cables
laid diagcnally across one another. The
lStter IL represented by Goodyear. and
In these tires the carcass n built up OF
q greater number Of layers Of very heavy
threads. which are closely woven to-
gether.
For the cord tire in general It u point
eG out that its construction permits low
er. imitation pressures with greater re-
siliency and longer life. The tire stands
up rounder under the car With less air
pressure than does the fabric type.
In addition to these two big makers
of cord tires. many other large makers
are adding this type. Firestone now is
making 500 a day: Empire now has them
on the market: the United States has
q cord tire on the market.
One reason for the popularity OF the
cord tire Is that its construction permits
the manufacturer to more nearly sp-
proach the ideal in tire making which
Is to produce q tire that will wear out
all over all at once. That Ii to say. q
tire in which the carcass will be worth
less by the time the tread il worn away
and which the tread viii be worn away
when the carcass goes. This. In short
Is the balanced tire.
Striving Toward Ideal.
Every manufacturer II striving toward
this ideal Samples Of tires in use all
over the world are collected and exam
med In some It 10 found that when the
carcass has gone there still remains quite
lot Of tread rubber which, Of course,
Is Just waste In others the tread has
gone. but there still remains some car
csss.
When the truly balanced tire Il real
lied 1t will mean much to the manufac-
-turer and much also to the user and the
dealer. It will bring down the cost Of
manufacture and consequently the SELL
ing price. This year tirss are better bal
anced than ever before, and next year
there will be still further improvement
Cord tires approach the ideal more
closely than fabric styles because the
carcass II the limiting factor. Tire car
casses fan because Of continual bending
at the sides. This places great strain on
the walls, which In time split The cord
tire win Withstand the maximum amount
of bending without splitting.
