RESILIENCY EASY TO NOTE

more than usually interesting tire test
was made yesterday morning on River
side Drive. in which w. II. Yule. manager
of the local Goodrich branch. showed
something of the resilency and motor
saving qualities claimed for the Silver
town cord tire. Lack OF internal friction
due to the absence OF cross fbres. gives
economies in gasolene, and further than
that makes the car run further and faster
with a less expenditure of effort than
with fabric tires. according to the makers,
who claim 80 per cent. greater general
efficiency when these tires are used The
things Mr.. Yule showed yesterday were
impressive.
The car he used. 1871: Stevens Dur
yea, carried four passengers. Although
he performed one set of experiments with
Goodrich fabric tires and then changed
to cord tires of like pressure all around.
for reader comparison the results OF each
feat will he given side by side
First he halted AT the top Of the grade
on riverside Drive at Ninety second
street. Putting the gear In neutral and
shutting on the throttle. he let the car
coast. The speedometcr showed twenty
miles an hour opposite Ninety NTH street.
the car down so that i just made the
southern corner of Ninety-siNth street.
but couldn't get across the viaduct. With
the cord tires he was moving twenty-five
miles an hour at Nnety-fifth street.
crossed the viaduct completely at four
teen miles an hour and halted on the next
upgrade even with Ninety-cghth street,
thus two blocks further than with the
other tires.
His next move was to start at ten miles
an hour from Ninety second street coast
ing down In neutral after crossing the
street line. lie got up to 20 III. p. II. at
Ninety-fifth street. crossed the viaduct
at m. p h.. and with that momentum
stopped just short OF Ninety seventh
street. With the cord tires making this
experiment, the speed attained was
twenty-siX and one half miles an hour
at Ninety-fifth street and the car cross
ing the viaduct at IS m. y. h. halted only
at the near side OF Ninety ninth street,
again two blocks better than with tho
other castings. II is TO be observed that
the performance OF the fabric tires with
the ten miles an hour start was ilfty-iive
yards short of the cord tire performance
from a standing start
Going down the drive Mr.. Yule got UP a
speed OF 20 NJ. p. h. climbing the hill from
Ninety-nfth to Ninety second street run
ming on second speed. There was "A diff
the cord tires as climbers. although in
second speed the difference was not as
marked as it would have been In high
speed,
The last feat was coasting on the Nat
Taking OFF, at Eighty sixth street at 20
IN. n. p. the car halted at the southern
corner OF Eighty-eighth street. With the
cord tires II ran a quarter OF a block
beyond Nneteth street from the same
takeoff.
There was perceptiblc difference in
buoyancy and riding qualities between the
two sets OF tires. 1t IL explained that
'the absence of cross hbres does away
with much internal friction, Tho tire
easily conforms to road inequalities with
out using valuable engine force to NeA
the tire, as with fabric tires. where the
warp and wool rub and generate heat.
Because OF the construction the tire Is
free from stone bruises and new sections
can be added. making repairs easy.
MANY attempts have been made to
make resilient tires. but 1t has been done
always at the expense of durability These
tires are resilient. more comfortable, faster
and economical and are durable too"
