Almost from the beginning OF

said Mr.. Olson. This is a natural

should strive, because Of the tire it

could not hold together nearly so
long.
Reduce Power Loss.
Comfort, minimizing Of vibration
and delivery Of an added amount Of
power from a given engine could be
accomplished only by the use of "A
tire constructed as IS the present day
cord. Automobile engineers have
found that so percent Of the power
generated by the motor rs lost before
II is delivered in the form of speed.
Much OF this power loss is through
the tires themselves. Cord tires re-
duce this loss TO a minimum Cars
equipped with cord tires have negO-
tiated steep hills in high that fail on
the same hill with fabric equipment.
This has been proven scores of
times and is a practical demonstra-
ton OF the additional power cord
tires give a car.
There is no question that the
cord constructed tire is most eff
cient IL may be said TO add tone
TO the car, the car rides easier; l.

less gasoline; It Will steer easier, and
can pick up quicker.
Demonstrates Strength.
'As constructed during the last
few years, it actually has demon
strated marvellous strength. When
automobile racing was at its height
il was found that only cord tires
could deliver the speed and stand up

racing driver must give any tire

has caused IT 10 be used almost eX-
clusively on the larger, more eX-
pensive automobiles.
while the cord tire is still dis
