THREE KINDS Rims
now BEING USED
ON AUTOMOBILES
Fixed and Demountable Cinch-
ers and Straight Sides Are
the Best-How to Get Rims
Into Position.

There are in general use today three
basic types of rims-the fixed clincher,
the demountable clincher and the
straight side. There are variations of
these, such as the universal. which Is
a side ring type. convertible from
straight side to clincher merely by re-
versing the side ring. The fixed
clincher type Is used on only one make
of car-the Ford--and the writer un-
derstands that the greater part OF the
present production is going to come
through with demountables. The de-
mountable clincher il used to some
extent and is a nexcellent type. 1t Is
simply an ordinary clincher rim, with
which soft bead clincher tires are used.
but instead of being fixed to the wheel
the rim is held in place by means OF
the usual Tugs. The split rim is the
type generally used for straight side
tires. This 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 ring by means OF
which it may be made to accommodate
either straight side or clincher tires.
The automobile owner of today using
split rims finds the greatest difficulty
in mounting and in demounting tires
especially after the rims have been In
use for some time and rust has set in
the locking device. Also the rim may
,, be slightly out of shape, or If not when
the tire is demounted, when it is ready
to be put back on. The make shift
method of forcing a split rim into po-
sition 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 prop
erly distributed, otherwise the ends OF
| the rim will not properly come to-
gether.
| 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 it will do little
good to hammer away sufficiently to
bend the rim. It>only makes matters
worst. If an owner finds great diff
Guilty in operating the rims it is sug-
gested that he use one of the numer-
GUS types of rim expanding tools de-
signed especially for split rims. One
| of the best designs grips the clinch
| firmly and pulls the rim ends apart
when the tire is being demounted and
pushes them together when mounting
| is done. This uses a rack and handle
control and is operated like jack. An
| other type employs a turnbuckle in the
middle. The accessory shops handle
various types, some of which are COL
lapsible, and in that condition may be
| placed in a door pocket.
| Drivers who are observing have nc
doubt remarked about the car ahead
having a wabbfng 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 posi-.
ton. This may be due to loose, worr
Jugs, poorly designed Tugs, one Of
more Tugs not in place, worn fello'
top or a bad rim. No matter what tn,
cause the tire on that wheel wears rap
idly and the owner should correct thu
trouble.
Rim Jugs give lot of trouble, SOM
because they never can be tightene'
in place, others because they Away
squeak. The ordinary lug on cheape
cars does not last long before it give
trouble. The owner may cover tn
lug with a piece of leather or SHIN II
but usually looseness sets in and TIN
rim squeaks. If the owner wishes t
: get new Tugs he may we'll invest in tn
type which cannot be lost from tn
wheel This lug has the nut in combi
nation and the two parts are perma
: nently attached to the wheel. Thi
type does not squeak as much as tn
regular design.
The rims themselves should Away
: be free from rust and to avoid an ex
cessive accumulation which freezes
:: the tire in place and makes operatio
4 difficult (especially the side ring type
: it Is suggested that the rims be painte
: with graphite or kept well protected b
some other paint.
