PNEUMATIC TIRES
FOR TRUCKS NOW
Innovation Put Out by Goodyear
Company Already Proved
r a Success.


building is the Goodyear Cord Pneu-
matte Truck Tire. There is now on
exhibition at Sanner & Berry's, $50
Fourteenth street northwest, the larg-
est pneumatic truck tire ever made.
The nominal dimensions of this phe-
nomenal tire, which is of cord con-
struction, is 4Sx12 inches, and the tire
is made for five and one-half and six
ton trucks.
Only a few years ago, pneumatic tires
for trucks were unheard Of or believed
impractical. but great changes can come
about in a short space OF time Now
Goodyear puts on the market a cord tire
for trucks. a cord tire which has already
proven successful
Goodyear's own trucks were the first to
be equipped with pneumatic tires. These
trucks do considerable trucking and
hauling between the factory and station.
and to the city. A certain amount Of
speed Is required on these trips which
means very much vibration. This con-
slant tarring. due to no one fault OF the
solid tires. but to the fast driving. dam
aging truck mechanism and making
continual repairs necessary.
First Noticeable effect.
One OF the first noticeable effects Of
pneumatic tires on these trucks was the
reduction in the number of repairs. The
trucks were seldom in the repair shop.
yet they made speed up to thirty miles
an hour. This saving alone over a
period OF several months practically paid
the initial extra cost OF pneumatic
equipment
Then began the manufacture Of pneu-
matte truck tires in three sizes, each
one having its own natural rim size-the
Ssxs inches. Ssx7 inches, and 42x9 inches.
The 36x5-inch rim could be furnished in
either the Goodyear Ideal Detachable,
or in the Goodyear Ideal Detachable De-
mountable types; the 3Sx7 inch-rim was
made only in the detachable type and
the l2xs inch casing required a cast steel
wheel. A little later. a IOxS inch casing, |
an oversize for the 3Sx7-inch casing and |
fitting the same rim was added to the |
line. This made a complete line OF |
pneumatic tires to fit trucks Of any ca
pacity up to three tons and for front ]
wheel equipment on even a few larger |
trucks. |
own Special Field.
Although pneumatic truck tires as
allaround equipment can be used on |
any truck up to three tons capacity, |
are not in competition with our solid |
tires. A large percent OF the trucks |
today are equipped rightly with solid |
tires. The slow-moving heavy duty /
trucks should have solid tires, but fo- /
the light, speedy truck, Goodyear ex-
perts believe pneumatic tires are the |
logical tires. In other words the di-
viding line between solids and pneu-
matics for trucks is to large extent.
speed.
Pneumatic truck tires are especially
adapted for light fire apparatus, pas
senger carrying buses and the lighter
trucks OF from three-fourths to two |
and one-half tons capacity, particular
ly where loads liable to damage in \
transit are carried. where road condI-
lions are bad, or where speed Is de-
sired. ]
Included I'm Field.
Included IN this field are trucks
owned by wholesale groceries, furni- |
ture and department stores, express
and hardware companies, breweries
and bottling works, bakeries, and by
many otherfs of a similar nature. |
Moreover, trucks making long hauls +,
need pneumatic tires for speed and
resiliency.
Another big advantage OF tfR pneu-
llTG Is lndl. uut 10 It's
extreme resiliency, II permits trucks
70 operate with considerable speed
without injury or additional truck
up-keep expense. Truck manufac-
turers realize this, and many will al
low the speed governor to be set at
a much higher rate of speed on their
trucks that are equipped with pneu-
matte tires. The result of this in
creased speed is greater truck mile |
age per day, and quick delivery-in
short, greater efficiency in CONNER
cial car Transportation.
Cord Tire Better.
Just as the cord is to the fabric in
regular automobile tires, so is the |
cord to the fabric in pneumatic truck |
tires. The fabric pneumatic truck tire |
Is a good tire-the cord is better, due |
to its superior construction. In Sc
we're passenger bus service IT should !
give from 5000 to 10000 miles, and |
much more than that in commercial /,
car service.
The cord pneumatic truck tire is i
built like cord automobile tires. differ |

heavier beads and side walls.
With railroad conditions bad as
they are now, and constantly growing |
worse, there is springing up consid-
