PART 2
jpncumatic Tires
The great . advantage of the
, pneumatic tire is that it can ab
sorbt obstructions on the road
without ! raising the axle. For
this reason, it will eliminate the
many small vibrations and jars
arising from the many small ob
structions or road inequalities. A
tire containing air under pressure
is very quick in yielding and in
returning to its, original position
(as .compared with a solid tire)
hence does not consume as much
power as a solid tire and will have
more speed. ,
Other: advantages of the pneu
matic tire are greater deformabil
ity, that is. it will deform or
adapt Itself to the road surface
more readily than any other tire,
and in consequence it is easier
riding. It has a higher elastic ef
ficiency,! or in other words, it con
sumes less power than the solid
rubber tire. The disadvantages of
the pneumatic tire are its well
known susceptibility to punctures,
blowouts and valve leaks.
The air in the Inner tube is re
tained by the fabril casing; of the
tire; this casing must be strong
enough, it must be composed of a
sufficient number of plies of duck
or fabric to withstand the air
pressure inside the tire. The
thicker! the casing or carcass of
the tire; that is to say, the greater
the number of plies or fabric of
which it is composed, the lower
will be Its efficiency, for more
energy is required to deform it or
flatten it as it rolls on the road
and is accommodating itself to the
road surface. ! To demonstrate
the amount of power which is was
ted even with pneumatic tires, try
to indent or flatten a casing by
hand before any I air is : pumped
into the tire. When a car is in
motion four tires have to be de
formed continuously and this con
sumes power. :
Cortl Tires
The more flexible the wall of a
tire Is, the less Is the power wast
ed and the greater is the tire
efficiency.- In a cord tire the car
cass is made of a number of
strands of cords j tied together,
(and not of cotton duck, as in
fabric tires) and this can be de
formed much ! more easily than a
fabric tire. For ithis reason a
cord tire is "faster" than an or
dinary fabric tire. Being softer
and more "deformable" a cord
tire will also absorb larger ob
structions on the road, as for in
stance when passing over stones.
Its absorption quality is better,
there will not be so much, pressure
between the small stones on the
road and the tire, since the tire
will largely rest on the road sur
face while at the same time, per
mitting the small stone to imbed
itself into the tire. For instance,
say a small sharp stone projects
one-half inch above the road sur
face, the cord tire will absorb the
stone so to say and yet the max
imum load will rest on the road
surface in front and behind the
stone. A fabric tire would not
be able to absorb so high a stone
and hence the entire load support
ed by the tire will be resting on
the small stone. ' If this should
be sharp, a puncture is liable to
occur. This is the reason why
less trouble Is experienced
through punctures with cord tires
than with ordinary fabric tires.
Balloon j Tires ;
A balloon tire is pneumatic tire
with a larger amount of air and
a lower air pressure. In order to

A service which promises to be

greatest step in the rapid advance
of the motor bus industry, will be
inaugurated when the Motorway
Tours (Parlor Car caravan leaves
New York on November 10, for a
transcontinental tour of thirty
days to Los Angeles. This won
derful motor train will consist of
four luxurious Pierce-Arrow
twenty-passenger : parlor ; cars,
equipped with deeply upholstered
individual chairs. The equipment
and service to be embraced on this
tour mark the establishment of a
new high standard in American
travel, offering remarkable com
fort and easy riding qualities, with
splendid view of the country
through which the motor train
will pass. i :
The route to be followed by the
"Covered Wagon of 1924" is as
follows: New York,' Philadelphia,
Gettysburg, Pittsburgh, Cleveland,
Chicago, Omaha, Newton, Kansas,
Garden City, La Junta, Colorado

support the load of a motor veh
icle, it is necessary that the air
pressure in the tire, balance the
load resting on it. If the pressure
is lower, the tire will flatten out
more so that a larger area is on
the ground. By-making the tire
larger it is possible to have a
larger area on the ground with
out damage to the tire. It can
flatten more and yet have ample
space between the road and the
tire rim, and on this account ; a
balloon tire can operate with t a
lower air pressure and the car
cass need not be so thick or so
strong. Being thinner, the casing
will be more flexible, more pli
able. .
With an ordinary pneumatic
tire If the air pressure is low and
the tire very flat, the fabric In
the tire is bent to a comparatively
sharp angle and therefore the life
of the fabric is short, and bend
ing the fabric so much will also
consume more power. If the tire
is made larger, a larger area of
tire can rest on the ground with
out bending the tire fabric to such
an extent. Since the pressure in
a balloon tire is lower and the
wall thinner it will absorb larger
obstructions on the road Without
raising the axle, than the ordinary
pneumatic tire, and on account of
its greater depth or larger amount
of air in the tire, it will cushion
the car more effectively. This is
the reason a balloon tire rides
more easily. On the other hand,

Compressed Air Motors
Roar Up German Hills
BERLIN, Nov. 9 (AP) Compres
sor motors "on - automobiles ahe
finding favor In Germany with
drivers who want speed. This
compressor attachment is similar
to the supercharger as used for
high altitude airplanes; compress
ed air is forced into the intake
manifold and results in a Super
charged fuel air feeding the cylin
dersv i ! v
; The result of the compressor's
action' is an instant additional
power impulse, amounting to more
than 50 of the normal motor
performance. For Instance, climb
ing a steep hill with full power
and a motor slowly decreasing in
revolutions, a compressor-equipped
car will suddenly leap forward
with a roar and pick up new speed,
after the normal maximum limit
has been reached.
! SEAPLANES TO USE SAILS
; LONDON, Nov. 2 (AP) All
metal seaplanes with masts and
sails to fly are possibilities of the
netar future, according to Dr. Wil
helm Rohrbach, who lectured re
cently before the Royal Society of
Arts in London. He emphasized
the safety and utility of seaplanes
carrying sails, and said this fact
might open a new era for naval
seaplanes, as it meant they could
sail at sea without using gasoline.
OWsmobile with exhibit at Vir
tually every, automobile show and
salon during the 192a season,
starting with the Twenty-fifth Sil
ver Jubilee exhibit opening In
New York City, January 2, fac
tory officials announce. Last year
Oldsmobile was represented at
shows held In 143 cities in this
country as well as several foreign
salons.
While figures are not available
Olds Motor Works feels justified
in making the claim that it has
been represented at more auto
mobile shows than any other
manufacturer. The Olds Motor
Works is the oldest automobile
manufacturing company operating
today, having been formed in
1897, more than three years prior
to the advent or the first auto
mobile showt The first year real
production started 1900 saw
1400 of the famous little curved
dash one cylinder "Merry Olds-
mobiles", built and sold. .
From the earliest days of auto
mobile exhibits Oldsmobile has
taken an active part in these dis
plays, which did t much to foster :
the popularity of. the motor car.
Factory officials are of the opi-
nin that these exhibits, even today
when the, automobile has reached
the high mark of being the second
largest industry in. the country
are, of untold value.
"These exhibits perform the i
same function for the automotive
industry as do central markets
and department stores In other
lines of ' trade," said Thomas
O'Brien, assistant sales manager
of Olds Motor works. "By means i
of the shows the public is given
an opportunity in its natural de
sire to shop around and see what
is being offered. Many persons
dislike shopping along "automo
bile row" lowing to their being!
importuned by salesmen every i
time they enter a show room. At
the show, however, they can look
to their heart's content and seei
just what the motor industry has
to offer them.
"Actual orders taken during the
shows usually more than pay for
any expense involved, but with
out doubt thre or four times this
number of immediate sales result
from the annual exhibits in the
weeks following.
"Another important feature, is
the . wholehearted support given
these exhibitions by the news-1
papers of the country. This at-i
titude clearly indicates that the
editorial mind or America rightly
places the automobile business at
the top of the list or the country's
essential industries. Anything
that. gains, the undivided suport of
ithe public press must be funda
mentally sound."
In addition to the various body
types of the six cylinder Olds
mobile, a cut-away chassis, show
ing in detail every working part.
will be included in most of the
show exhibits of Oldsmobile dur
ing the coming season.
Dodge Brothers Motor Car owners

But they do not pay in advance for-
service they may never need.
That is because Dodge Brothers do
