The cToss-section Of inner tubes is
made a little smaller than the normal
air space inside the cases. 1t is not

fabrication is most important to

matter that is given least attention.
Practically al tire manufacturers
treat the inside of cases with a white
solution to prevent tubes from stick
/ ing to the adhesive friction" Of the
fabric. A good lubricant, however,
should be used.
Some motorists neglect busting
soapstone inside of the case when
changing a tube-others use the soap
stone so sparingly that it does but

so much that it does more harm than

1t is esseutia. that tubes be equip

have in me past furnished tubes
with specially equipped valves for
cllrcher cases, another type for O. D.
! clincher cases. and still another tyne
for straight side cases. The clinct-
er valve spreader will not properly
/ lock the @. D. clincher beads on a
Q. D. clincher rim, nor the straight
side type of tire on a straight side
rim. The valve equipped with
straight side spreader will lock the
beads on a clincher rim or a @. y

Don't overlook the importance of
having tubes with properly equipped
valves. Care in this respect will in.
sure a proper anchor of tire to rim
end eliminate much annoyance from
tube pinching near the valve. Pinch
ing OF an inner tube usually occurs
/ from oversight or carelessness in
the application of the tire to the
rim
When a tire is ridden soft there
! is a tendency for the beads to lift
up at the toes, due to the internal
pressure and weight Of the car and
they sometimes permit the tube to
work under the bead. This is ag-
gravated when the tire has been con-
tinually ridden soft and beads have
been cut and broken by the rim.
Don't crowd tire of wrong size on
rim simply because you are able
to do so by physical force. 1t isn't
economy-aside from the injury to
the beads, much annoyance can be
expected from tubes being pinched.
All straight side and quick detach-
able clincher cases should be equip
