expected outbursts from air-con-
tainers originate from "sins of
omission" and commission" and
by emphasizing the more glazing
ones the Goodrich company believes
it can save the motorist dollars
that otherwise would pour into the
abyss of waste.
Undue haste in replacing a pune
tured or blown out tube is respon-
sible for a multitude of these
Sins. The most common mistake
is pinching the tube. The tube is
inserted in an uneven or twisted
manner This causes it to overlap
or wrinkle with the result that in
a short time il will cut through
where is has been overlapped and
we have a leak. The same trouble
is also caused sometimes by put
ting a new tube into the tire just
as it is taken from the box, When
the tube is applied after mounting
there is such an thrush of air that
it will often buckle up the tube.

Especially will this occur If the
valve stem is not pulled out TO it's

should proceed slowly when apply

should be applied carefully, the in
side-the side on which the stem
occurs-being always kept inside
"talced" carefully and the fingers
forced all around the tire TO make
sure that the tale has been evenly
distributed, and then, before the
loose bead is applied, the tire
should be given a little more air
enough TO round it out nicely and
prevent pinching.
The motOrist should be caution
ed against using too much tale.
There are several powders procure
able for keeping the tube from
sticking to the casing, among these
being soap stone, graphite and tale.
but the use of too much of any of
these proves disastrous and a col

flated tire passes over a stone both
casing and tube are jolted against

inflated to the standard prescribed
by manufacturers.
If a tire debates suddenly the
car should be stopped Immediately
as continuous running means that
the casing must slip circumferen-

and tearing the tube.
Sand in a casing is another cause
of the ruination OF a tube. It very
often happens that a motorist,
while repairing a puncture on a
road, permits the tube and casing
to pick up particles which create
a friction later and eventually tiny
holes, which will scarcely show
when the tube is submerged in
water, assert themselves. Then
the motorist runs to the dealer and
charges him with selling a porus
tube.
Putting understood tubes in cas-
ings is common fault. This
