one Of the prevailing tendencies Of tho

Individual car owners has had noticeable
effec. upon all the leading automobile
manufacturers AMI Il is not only upon
pleasure cars that this equipment is being
used. as IT Is also made in dual form for
equipping two pneumatic tires TO each rear
wheel OF heavy trucks. motor fire appar-
atus ambulances. patrols and other heavy
vehicles which are operated at high speeds.
This subject is just now receiving 50
much attention from automobile manufact-
urtrs and owners alike that the following
general remarks by the Firestone Tire and
Rubber Company will be of especial inter-
est:
THE most approved type OF rim consists
of demountable rim for removing tire,
rim and all from tie wheel and substitute
ing an extra tire carried already inflated
oil a spare rim combined with a quick de-
taohable tire device for detaching the tire
from the rim itself
The earlier types OF demountable rims
were designed for regular clincher tires and
required short stem staybolts 10 hold the
tire safely on the rim. The work or fore
ing the tire over the clinch/ OF the loose
detached rim and the inconvenience OF fit
ting the short staybolts was a great draw
back TO this type Of rim.
when the quick detachable feature was
added to the demOuntable rim. the combina-
ton proved 10 be all that could be desired.
Quick detachable tires eliminate the use
OF staybolts altogether. and the Firestone
rim permits changing the tire on the rim,
no matter whether the rim is mounted on
the wheel or not. This is an important
point as in some types OF demountable
rims IL is impossible 20 detach the tire from
the rim until the rim is demounted from
the wheel, limiting the tire changes trip

The severe service TO which A demount-
able rim is subjected calls for greater
/ strength and more careful designing that
al first thought would seem necessary.
| Every revolution of the wheel Is ike a
| blow from a hammer reinforced by the
whole weight and momentum Of the car
| tending to pound the rim out or shape anu
make il hard to demount from the wheel
The only way to eliminate this tendency Is
10 have a continuous bearing surface be-
tween the demountable rim and the wheel.
such al Is found in the Firestone rim. Some
| tvpes Of construction have this bearing sur
face at only a few points, allowing the ball
ancc of the rim TO work out Of shape and
| bind on the wheel"
