TIRE REPAIRS
Most Satisfactory Method of
Repairing Pneumatic and
Fabric Tubes Explained !;
Retreading Uneconomical.

Now that So many trucks operating
In every conceivable kind Of service
are rolling ON large pneumatic truck
tires. I am often asked what is the
most satisfactory method Of repair
Ing tires that have suffered tread or
carcass injury" states G. r. Drummer.
manager Of the service department Of
the Goodyear Tire ana Rubber com
pany.
I'm the first place. any repair. to be
successful. must actually be worth at
least the amount OF money invested in
1t. and repairs on large tires are nat
Nrally more expensive than on small
ones. So. the first thing to he de-
termined is whether the service that
can reasonably be expected warrants
the outlay Of the expense involved.
Small cuts IN the tread and the
sidewalks should be promptly repaired
with tire putty by the truck driver. to
prevent gravel and water from enter
ing. which would cause enlargement
of the cut and eventual separation of
the tread from the carcass The most
dangerous tread cuts arc found in the
grooves between the diamond shaped
blocks OF rubber.
III the cut is too large to be repaired
by the use Of tire putty 1t should be
taken to n repairman. The treatment
Of such repair In large pncuma
tic tire is the same as that used on
tires for passenger cars. except that
the large tires are vulcanizcd in tread
aud side wall surface, sufficient hear
for vulcaniZation cannot be secured III
4, sectional mold. IT is absolutely cs-
sential that repair on Il pneumatic
truck tire be properly cured. So, to
insure perfect job. the pot heater
system is used. and the repair vulcan
lied In open steam.
1T is our aim to build 4 perfectly
balanccd tirc--one that delivers its
full service before any particular part
Of the tire gives way. and. We there
fore. put on a tread intended to wear
until the carcass Of the tire has out
lived it's usefulness. SO that when tho
tread has wor ndown pretty wen. II is
obvious that good wear has been OBJ
tanned.
Many motorists are In the habit Of
rctreading their pleasure car tires
when conditions are right but we do
not recommend the rctreading of large
pneumatic truck tires when tread
separation has developed In cases Of
premature tread separation a rctread
will. in all proba bility be no more
successful than the original tread
Tires that are constructed properly
and used properly should not develop
fTSad s.e,Ipp;afraton, BIT when this DOGS,
develop. the tire should be run as long
as possible. for tho carcass alone is
strong enough to hold ny for several
hundred miles. The job of rctreading
could. Of course. be done but its econ
omy Is doubtful. Fortunately our tires
seldom fail because Of this condition.
Continued use in many kinds Of
service in all sections of the country
has shown that these hi: tires are not
susceptible to any class Of injuries
that cannot be repaired in a manner
similar to that used in the repair of
tires for passenger cars. our pneli-
matte truck tires are made in tho cord
construction and are. therefore, not
liable to many of the failures that fab
tic tires are subject to- Our expert
cnce with these big tires in actual
service confirms our previous belief
in their practicality."
