SUPER ALLSTATE
TIRE, DEVELOPED


cwncr, Ike To nave a set Of tires
which is. guaranteed to run three
years at the average mileage made
by the audtomobilcs in the United
States?
How would you like TO drive
your car on Il set Of tires guaran-
tccd to run 25,0Go miles,
Such a tire called Super -tllstatc,
has been developed and put on the
market by Sears, Roebuck & Co.,
and the guarantee carries no re
strictionS. Il is complete and
blanket guarantees of which the
purchaser Is the final and absolute
Judge rs to whether or not the tire
has run 25,000 miles and otherwise
performed in 4 satisfactory manner
Some tire manufacturers, some
wears ago, announced that the pol
ley of guaranteeing tires for mile
age had been discontinued. Other
automobile tires carried a guarantee
against defects in workmanship and
material. This was the condition of
affairs when Sears, Rocbuck \ Co.
began the development Of an auto
mobile tire which would hc guaran-
tccd for 25.00O miles of running,
the guarantee to be a blanket guar
antcc in every way. As the average
mileage made by automobiles in the
! United States j. approximately
5000 miles. this tire was to be built
to run three years at the average
cars mileage.
Early in the investigation it was
found that the tire desired could be
made with no great amount of trou-
( Bile, using the new methods which
! have lecn developed in the making
/ Of tires. provided the price Of the
; tire to the customer was no object.
4 If the customer would pay enough
money. much more than he had been
uaviug for any tire. a $4,000 mile
guaranteed tire could be produced.
However. price is an object and the
company hcgar battle with phys
ical conditions to make tire which
/ would rum $4,000 miles under a blan-
. kct guarantee and still could be
bought at a price which would be
cheap for the service the tire IS
guaranteed to give.
Started Year Ago
Work ON this tire was started ear
Iv in 1927. BY the fall of that
wear tires were being produced
which seemed 10 give the desired
results on the testing wheels in
laboratories and factroy. However,
that rest was not considered severe
enough so a heavy. high priced au-
tomobile. heavy car Of less price.
a car in the $500 class. light ear
