Various Conditions Outlined.

lows less vibration in the truck.
The high-Size tire costs more. and
therefore should be recommended only
for such uses as will bring a return
in proportion to the extra money in
vested.
THE high-size truck tire can be
used most economically on the front
wheels of all trucks above the 1 y ton
capacity operating under the general
conditions heretofore enumerated, but
where, in addition. the following re-
quirements are important: % A de-
mand for cushioning effect mot as
great as that furnished by pneumat-
les, but greater than supplied by reg
ular tires: for example. where a solid
truck tire is compelled to run regu-
larly over rough city pavements: (2)
whenever it is eXpedient to carry oc-
cas1onal heavy loads: such as large
pieces of machinery: CD where the

time between periods of replacement: {:

long distances from tire application
facilities. such as in isolated rural
districts; (5) to improve the steering
qualities on heavy duty trucks.
Single Type for Rear Wheels.
'The big single type Of solid truck
tire is designed and built to take the
whether high size or regular. The
field for this tire is at present on the
rear wheels Of trucks of capacity
above one and a half tons. requiring a
tire Z inches to IA inches in width.
1t takes the place of cushion tires
and cushion wheels. carries heavier
load than dual tires of the same
cross-sectional width and maintains
this carrying capacity as we'll as all
other features. undiminished through
out its tire life.
'"The development and perfection of
the pneumatic truck tire--the type of
pneumatic that is built especially for
trucks and is not merely an enlarged
passenger car type-stands out as
one OF the greatest steps in truck
evolution. There is now no question
but that its place is established for
use on all trucks up to and including
two-ton capacity where the elements
of traction, speed and cushioning are
especially needed in truck operation.
Swing to Pneumatics Rapid.
''The swing to large pneumatics has
been so rapid that many mistakes
have been made in marketing them.
This company believes that sizes
above eight-inch have not yet been
developed beyond the experimental
stage.
Pneumatic truck tires may be used
economically on the front and rear
wheels of trucks of capacities up to
and including two tons and on the
front wheels of trucks above the
two-ton capacity. operating in the
following classes Of hauling work:
General farming, dairy, egg and
chicken industries, bottling indus
try. furniture manufacturers and
dealers. wholesale produce dealers,
department stores. fire trucks of light
and medium types. rural transfer
companies, rural distribution of gaso-
line and oil and intercity single deck
passenger buses.
Pneumatic truck tires have come
into use in helping to solve trans
portation problems more extensively
in the middle west than in the middle
Atlantic or New England states. The
reason is one Of road conditions. cou..
pied with the fact that smaller ca
pacity pneumatic tire trucks are most
useful and economical in farm terri

farmer Is probably the largest user of
the pneumatic tire truck. AS in farm
ing. SO in the other lines Of work
mentioned. pneumatic truck tires
have come into use on lighter trucks
