Covering Must Have Reasonable
Care and Consideration From

SALES MANAGER FOR
GOODRICH GIVES VIEWS
Equipment Should Not BE Made
TOp-Heavy and Cumbersome,
Says F. l. Reynolds

In an article by ID. M. L.. In the Octo.
Der End Issue of The Automobile. +.
I. Reynolds. sales manager Of the
Pneumatic Tire department OF The
B. F. Goodrich Co.. pointed out the
merits Of diversified tires.
I'm this article Mr.. Reynolds said,
I'D. l.. M. doubts the merit of over
sized tires for city work. There is
not the slightest. doubt but that II
ideal conditions of the use of the or
iginal equipment of any automobile
were followed, there would be no
necessity for diversified tires.
THE manufacturer Of q car, after
due consultation with the manufac-
turer of the tire. selects an equip
ment which II quite sufhcient for the
car az delivered by the manufacture
er. with the" presumption that the
specified number OF passengers = or
average weight will be the most the
car will be required to carry, but
when the user Of the car makes his
purchase, one Of the earliest things
he does ID to provide one or more
spares, which more frequently than
otherwise he hangs on the back Of
the car. and not infreQuently, he adds
one or two extra as q matter OF con-
venience to the number of passen.
gers designed to be carried In tne
car. Here Is the first demand for q
somewhat larger tire. st
Again the diversified tire has .
thicker tread. The ordinary ,unsx-
pected damages to, which car il sub
jected will, as a matter of course, not
affect, the diversified tire quite az. sert'
ously a. the regular. equipment tire
because. the thickec tread naturally
means that slight damages are. pro.
portionately less penetrating.
THE thought Of the average ase'
OF an automobile Is that occasionally
overwhelming a car d6es not injure -tire
tire, ana that it is necessary to- corr
tinue to use the car overloaded In
order to have amy bad effect This
IL not true. AhvenHe drive with this
excess weight In the car may start a
deterioration that will continue OF It
self without any outside. acceleration
until the tire has become useless
much quicker than Is expected OF 1t.
"The building OF tire is OF such .
character that an unusual and severe
strain for even short period OF time
may start the plies OF fabric to sep
arate or break some few threads In
one ply of fabric so that the action
OF the part In itself will advance de-
terioration much more rapidly than
ordinary service.
IAN additional advantage In over
sized tires is the easier riding qpali-
ties. A car equipped with tires that
are required to perform up to the
limit of what 10 expected OF them
must be inflated up to the limit pre-
scribed by the manufacturer OF the
tires In order to give the maximum
amount of service. A tire that Is car
rying much less In weight than the
prescribed capacity can be much less
fully inflated.
"The writer recalls very clearly q
car Weighing $3.50 pounds which was
equipped with ss6x4- tfres- BY the msH-
which gave according to
the equipment an excess OF 100 pounds
without load. The users Immediately
removed the 36x4 tires and replaced
them with S7x4 IL tires, which had
a carrying capacity of 400 pounds.
After the car was provided with spare
tires, robes. blankets, fuel, oil. etc.,
the car was weighed and found to
weigh $500 pounds. While It IL
four-passenger car It not infreQuent-
ly carries Ave passengers.
while the Imitation prescribed by
the manufactures Of the tires would
require for the 4inch tires 20 pounds
of air, the user has ridden the car
on 4 l-2-inch tires with 20 pounds OF
air, and the rear tires averaged UP
to 5000 miles and the front tires over
$500.
''The writer insists that this prac-
tice would prove a much more salts
factory advantage with the diversified
tires inasmuch as the car has been
used practically altogether on city
streets. Out OF the 5000 miles accom-
plished, probably not over 1900 were
on country roads. Part OF the time
was during a factory strike when
the streets were well strewn with
glass, nails, lacks and other matter
that would be- calculated TO injure
the tires.
Twice during the time the tires
were running the owner had a repair
shop go over all tile small cuts and
seal them up, which he regards as
no more extraordinary care OF tires
than having clothes pressed at fire.
ouent Intervals In order to get the
hest service out OF them.
Y much OF the difflculty In securing
service out OF tires is due to the own
err regarding them as something mys-
terious or superIative. not that the
tire Is nothing more than rubber
air bag incased In canvas cover with
rubber on the outside TO protect the
canvas from the elements. -''''
'Tf the owner OF car starts out
with the theory that he proposes to
drive on air. that In order TO ride ne
must keen the air receptacle whole.
and IN. order to do that must see that
the covering has reasonable care and
consideration. he will get satisfactory
