FABRIC INJURY

After Blowout Occurs Tires
Should Not Be Run Farther
Than Is Necessary.
EMERGENCY REPAIRS VITAL
Breaks Often Caused Weeks Previous

Object in Road While Run

Have your ever had a blowout when
your car was standing still, after COM
ing from a drive on a smooth. level
rOadl
Or have you had the experience Of
going out to your garage and finding
n perfectly fiat tire? 1t was all right
when you drove in the evening before.
Something had happened to it over
night.
You removed the tire and tube, found
the tube worn and a clean break on
the inside fabric Of the tire.
What caused the fabric to break?
1t is very probable that it was
started a week or even a month previ-
Gus, when you ran over a brick, a rut
or a hole in the street while running
at high speed.
Small Break at First.
Then again it may have been caused
when, in turning around In the street.
you allowed the front or real wheels
of the car to bang into the curbstone.
OF course, this is more likely to hap
pen if the brakes are not in good work
ing order.
At first the break may be small. but
the broken threads of the fabric at
the injury chafe each other while the
tire Is In use. setting up an internal
friction that quickly causes the break
to enlarge.
The other plies soon break down,
the tube is pinched and a blowout re-
suits. Generally this occurs some time
after the original break and when cir
cumstances point to no apparent u
1t is unfortunate that the bruise or
fabric break is seldom manifested by
any indication on the outside of the
tire, for the tough tread rubber
stretches when the tire strikes the stone
or curb, but fabric a only stretch a
certain limit, and when taxed beyond
that point will break. Often only the
innermOst ply is injured.
The best way to avoid stone bruises
Is to avoid hitting the stones, the
bumps and the ruts in the roads as
much as possible.
For Emergency Repairs.
After a blowout comes, do not run
the tire a foot farther than Is neces-
sary, but Immediately put into a tenn
porary repair or change tires, and as
soon as possible take the injured tire
TO the vulcanizer for a permanent re-
pair.
For an emergency repair on the
road use a rim-cut patch. 1t should be
applied without cement so that it can
be removed later on under less stress
full conditions, and a permanent vul-
canized repair made.
II the tire Is too old to be worth
.vulcanizing, a permanent repair can
be made that will allow the tire to be
used many more miles by using the
rim-cut patch, and cementing 1t in with
patching cement.
"How to Do the Job"
To do this follow these directions:
First be sure that the fabric at the
break Is dry, then clean the inside of
the tire thoroughly at the break with
gasoline for a space slightly larger
than the patch. After 1t is dry apply
two coats Of patching cement, allow
ing time for each coat to dry and be-
come tacky. Give the outside Of the
patch the same number of coats, and
after this cement Is dried insert the
patch by seating the toe Of the tire
bead in the crease in the patch wing.
Now work the patch down all the way
the tire, pressing 1t down firmly
and smoothly, and then adjust the 9th
err bead.
