FIRED point-blank into the
tread of a new military tire,
bullets from army rifles and
machine guns recently provided
a spectacular demonstration of
the ability of newly devised,
triple-layer inner tubes to seal
themselves when punctured. The
tires, developed for use in the
United States Army by labora-
tory workers in Akron, Ohio, are ex-
pected to prove valuable on gun car-
riages, antiaircraft gun mounts, and ma-
chines of motorized cavalry. Three layers
of special rubber compounds, one of which
is semiviscous, give the new tires their
ability to “swallow bullets” without being
punctured. The inner tubes formed of these
layers seal themselves without appreciable
loss of pressure when they are pierced by
bullets. At the famous Aberdeen proving
grounds, in Maryland, Army officers fired
50 and .30 caliber bullets into the tires.
One tire, pierced by .50 caliber machine-
gun bullets, continued in service for 200
miles without additional inflation.
