ADVICE ON RIl.S
And RIM DEVICES
Some Timely Information
On the Best Methods of
Handling Them.

There are in general use today three
basic types of rims-the fixed ciincher
the demountable clincher and the
straight side. There are variations of
there. such as the universal which is
a side ring type. convertible from
straight side to clincher merely by
reversing the side ring. The fixed
clincher type is used on only one make
derstands that the greater part of the
present production is going to come
through with demountableS. The de-
mountabte clincher is used to some
extent, and Is an excellent type. 1t Is
simply an ordinary clincher rim. with
which soft bead cllRcher tires are used.
but instead Of being fixed to the wheel
the rim is held in place by means of
the usual lugs. The split rim Is . he
type generally used for straight JIde
tires. Tbs type Is traversely split
and the ends are locked together so
that there Is no possibility of them
coming apart. The universal rim is
fitted with \ detachable side rig by
means Of which it may be T . to
accommodate either straight sc or
clincher tires
The automobile-owner of today
using split rms finds the greatest
difficulty in mounting and in de-
mounting tires, especially after the
rims have been in use for some time
and rust has set In the locking de-
vice. Also the rim may be slightly
out Of shape, or. il not when the tire
is demounted, when it is ready to be
put back on The makeshift method
of forcing a split rim into position is
to use a lifting jack and two blocks
of wood. One block is placed under
the jack and one above while the
jack 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 properly distributed 9TH
erw-ise 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 il
made very frequently. When a rim
cannot be forced in place with a nor
NAL amount of pressure it will 90 lit

10 bend the rim. 1t only makes mat
ters worse II an owner finds great
difficulty in operating the rims, II is
suggested that he use one of the nu-
r7erOCS typ. : Of rim expanding tools,

Drivers who arc observing have
: no doubt remarked about the car
ahead having webblin- wheel and
also the frequency with which wab-
bling wheels are seen Half the
cases are not due to the wheel at
all. hUt TO tho rim, which is not
firmly secured in position This
may be due to loose worn lugs,
poorly designed lugs. one OF more
luEs not in place, a worn felloe top
or bsd rim No matter what the
ca1Sc, tho tire on that wheel wears
rapidly and the owner should cor
rect the trouble
Rim luCs give a lot OF trouble
some because they never can be
tiEhtcned in place. others because
they always squeak The ordinary
luz on cheaper cars does not last
long before II gives trouble The
ownerl may cover the lug with
piece of leather or SHIN it but
usually looseness sets in and the
rim squakA If the owner wishes to
get new lugs he may well 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 s1way
be free from rust and to avooid an
exec essive accumulation which
freezes the tire in place and
makes operation difficult Especially
the side ring type) it is suggested
that the rims be painted with graph
ite or kept well protected by some
other paint
