Tire trouble has from the first auto

big bogie.'' The mechanism OF the
automobile has been perfected to such
! point that it is now estimated that
80 per cent of the stops for roadside
| repairs are due to tire trouble. In an
effort to ascertain some of the causes,
effects of and possible remedies for
this condition. Mr.. Clinton, the repair
| department manager. of Morgan &
Wright. the Detroit makers of the fam
Gus good tires,' was interviewed.
| I'm your opinion what is the chief
cause of tire troubles? 2" was asked him.
Improper initiation" he answered. Il
can prove by the repair records We
have on hand, that fully IS per cent OF
all tire troubles are directly due to this
, on cause.
1T is SO easy he continued. for a
motorist to neglect this important
point. Some car owners seem to think
their whole duty is done if they test
the pressure when they first initiate the
: tire. They forget that a minute leak
may daily decrease this pressure and
bring the tires way below the danger
line. Again, new tire will stretch a
perceptible amount during the first day
or two OF service. This naturally ex-
pands the air chamber and decreases
| the pressure to which it was originally
| inflated"

/ Il can,' he said, explain to better

should exert such influence on the SER
vice life Of a tire" Leading to one OF

planned each step of the operation in
making tire.
While very interesting throughout.
it will suffice to simply explain that
the tire is built up of strips of the
heaviest cotton fabric, thoroughly i'm
pregnated with compounded rubber
gum. This is laid up. layer upon
j layer, on annular iron cores into the
| familiar shape of a tire casing, the
| side walls being made only about half
/ as thick as the tread proper.
| THE side walls of tire" Mr.. Clin-
| ton explained. ARE built comparative
| ~ thin for a purpose. When the tires
are In use they are subjected to con-
slant flexing, or bending. as the car
/ h4 the
| road.
The life of tire depends to very
| large extent upon the amount OF bend
/ ing to which these side walls are sub
| jected. You will perhaps better ap-
| preciate this if use an illustration.
| A willow switch can be bent back and
| forth gently an indefinite number of
times without breaking. whereas will
| low stick of double the cross section
would break in two or three compare
| lively slight bends. This same prin-
cple is applied to the building OF an
| automobile tire-to make side walls
as thin as is consistent with the air
pressure they. are compelled to with
stand. The destructive effect OF the
side-wall flexing is thus reduced to a
minimum.
/ I'VE have reduced the effects OF this
bending as much as possible. but 1t is
entirely up to the automobile owner to
reduce the bending itself. A soft tire
will bend down nearly to the rim ev-
| ery time the wheel goes over bump or
| ridge in the road whereas the same
bump will give the side walls OF
properly inflated tire a slight bend or
/ none at all. Do you see now why we

while we make our tires as wear
proof, as puncture-proof and as trou-
Bile proof as it is possible to make
combination of rubber and fabric, SO
far we have found it utterly impossi-
/ bile to make them careless-proof. A
| driver can ruin the best tire on earth
/ in 500 miles of driving If he so Wills.
