The marked effect different makni
of tire have on motor power waa
ihowa in lieiwrml' recent announcn
niraU o( coasting and running twit.
To understand the reaann for tho"
extra motor power demonstrated
with the fieiwral Cord it must fir-it
be understood that all mnkes of tires
absorb a certain amount of motor
power. It is internal friction in
tirei that ca lines power 1. This
varies tremendously according to
ttm amount of internal friction in
each.
This Internal friction in tires
uses up motor power in the Bnme
way that friction in the working
parts of mnchincrj acts as ft drag
apiin.it power.
Trictioii is overcome by hi brie
lion. To prevent friction between
metal parts a film of oil is used. In
tho fume mnnuer, ruMier of the
Hurst grade ami in generous quan
tity U uned in the General Cord to
kwp the cotton plica separated and
rnch cord insulated.
Thus, by a proooss equivalent to
lubrication, (Jpneral ltas obtained
rentor freedom from internal fric
tion, and this is the reanon for the
extra motor power with the General
Cord in comparison with other
makes of tires.
Longer Mileage
and Low Pressure
Due to Less
, Internal Friction
The extra motor power with the
General Cord has on oven bigger
meaning than the gnsoline saving
,and the longer life of your motor,
for that lAiite special feature of con
struction that accounts for the extra
motor power aUo explains the longer
tire mileage General's greater free
dom from internal friction.
Internal friction is the greatest
. known destroyer of tire. Friction
always menus wear. . .And tin) tiro
with the least internal friction Is
naturally the tire that shows the
lowest wear, provided this advan
tage is gained, as It is in tho Gen
eral Cord, without reduction in the
number and weight of plies essential
to proper construction.
Jt was General' mastery of in
ternal fricjion that enabled it to
produce, Ave years 'ago, the first low
pressure tire ever placed on the
mnrket,
Just as today it his enabled Gen

General Shows How
Internal Friction
Is Overcome
The process of complete insulation
in the General Cord goes beyond the
commonly used method of passing
cord fabric through a thin solution
of gum dissolved in benzol. Gen
eral's special process, which can
only bo accomplished by putting the
cord plies through largo steel cal
ender rollers, gives every ply a
heavy coating of fluent rubber, uni
formly thick, forced liHween the
cords so that each cord is completely
surrounded end no two cords can

General Cord Users
Enjoyed Low Pres
sure Before Balloons
General Cord users did not have
to wait f'r balloons in order to en
joy low air pressure.
With cxjM'ricnee, in low-pressure
construction dating back beyond
tint n( any other niamilolurtr, lovr
pressure in Kegulnr size General
Cords had become a well-known fea
ture long before the advent of bal
loon tires. '
In fact, the history of General's
development of nw pressure is the
siory of tho evolution-of the balloon
tire. ,
This is tho background that ex
plains General's singular ' success
with low pressure, first with Heg
ulnr size cords nnd thea with 4-ply
end C ply balloons.

oon
General's 4-ply Balloon is the
practical equipment for the
smaller cars. For the heavier
cars the 6-ply has greater thick
ness to carry the load and still it
allows the full flexing action over
obstructions. At the same time,
it reduces Balloon puncture risk
to a minimum. And General's
6-ply Balloon consumes no more
power than the average 4-ply bal
loon because General's greater
freedom from internal friction al
ways means power and gasoline
saving.

Hundreds of thousands of car!
owners are enjoying the advan
tages of low pressure without
having changed their wheel
equipment they are using
General's low-pressure Regular ;
Size Cords. . ,
It was back in 1919 that General
produced the first low-pressure
tire ever put on the market the
General Jumbo SOxS1 Cord requir
ing only 30 lbs. of air.
This is the sixth year of low pres
sure in the General Cord and only
such long-standing specialization
can explain General's singular suc
cess with it in all Regular Size
General Cords as well as the Bal
loons, both 4-ply and 6-ply.
Come in and talk with us. We will
gladly demonstrate the low-pressure
advantages of the General
Cord for your car. If you prefer,
a phone call will bring us to see you.
