CONCERNING RIMS
AND RIM DEVICES
Some Timely Information on
the Best Methods of Han
ding Them.

There are in general use to-day three
ado types of rims. the fixed ciincher.
A.. demountable cllncher and the
s,raieht side There are variations of
.tese such as the universal, which is a
,JSs ring type convertible from straight
s,de 10 clincher merely by reversing the
sde ring. The fixed clincher type is used
an only one make of car, the Ford, and
,ha writer understands that the greater
a.r, Of the present production is going
- come through with demountables. The
Sanountable clincher is used to some
eytent and is an excellent type. 1t is
sln,nly an ordinary clincher rim, with
rrhch soft bead clincher tires are used,
hnt instead of being fixed to the wheel
me rim is held in place by means of the
usual lugs The split rim is the type
generally used for straight side tires.
This type is traversely split and the
snds are locked together so that there
is no possibility of them coming apart.
The universal rim is fitted with de-
tachable side ring by means of which
n mAy be made to accommodate either
straight side or clincher tires.
The automobile owner of to-day using
split rims finds the greatest difficulty in
mounting and in demounting tires, espe-
cially after the rims have been in use
for some time and rust has set in the
lacking device Also the rim may be
slightly out of shape. or. IL not when
the tire is demounted. when 1t is ready
TO be put back on. The makeshft
method of forcing a split rim into posi-
ton is to use a lifting jack and two
blocks OF wood. One block Is placed
under the jack and one above while the
lack is lying on the floor inside of the
rim. Operation of the jack then spreads
the rim. In doing this the blocks must
be- so placed that the pressure is prop
erly distributed, otherwise the ends of
the rim will not properly come together.
An error often made with one type of
rim is in getting the locking means to
overlap the wrong way. This may seem
like an impossible error for an owner to
make. but have seen it made very
frequently. When a rim cannot be
forced in place with a normal amount
OF pressure 1t will do little good to
hammer away sufficiently to bend the
rim. It only makes matters worse. If
an owner finds great difficulty in OPP
Grating the rims it is suggested that
he use one of the numerous types of
rim expanding tools, designed especially
for split rims. One of the best designs
grips the clinch firmly and pulls the rim
ends apart when the tire Is being de-
mounted and pushes them together
when mounting is done. This uses
rack and handle control and is operated
like a jack. Another type employs a
turnbucke in the middle. The access
sorry shops handle various types. some
of which are collapsible, and in that
condition may be placed in a door
pocket
Drivers who are observing have no
doubt remarked about the car ahead
having a wabbling wheel and also
the frequency with which wabbling
wheels are seen. Half the cases are not
due to the wheel at all, but to the rim.
which is not firmly secured In position.
This may be due to loose, worn lugs.
poorly designed lugs. one or more lugs
not in place, a worn felloe top or n bad
rim. No matter what the cause, the
tire on that wheel wears rapidly and
the owner should correct the trouble.
Rim hugs give a lot of trouble, some
because they never can be frightened in
place others because they always
squeak The ordinary lug on cheaper
cars does not last long before 1t gives
trouble The owner may cover the lug
with piece Of leather or SHIN It. but
usually looseness sets in and the rim
squeaks. II the owner wishes to get
new lugs he may we'll invest in the type
which cannot be lost from the wheel.
This lug has the nut in combination and
the two parts are permanently attached
TO the wheel. This type does not squeak
as much as the regular design.
The rims themselves should always be
free from rust. and to avoid an excess
sive accumulation which ''freezes" the
tire in place and makes operation diff
cult Especially the side ring type) it is
suggested that the rims be painted with
graphite or kept well protected by some
other Daint H.-- o.
