Tires are often considerable factor
in the expense of running trucks, but
they need not be if proper attention is
given to sizes. quality. etc.
For example: l have seen tires that
were very resilient, SO much so that the
rubber f1attened out to a great extent.
and the truck was using up a great part
of its power in pushing ahead the rub
Der just in front of the actual bearing
of the tire on the ground 1t had the
same effect as running uphill all the
time. On the other hand l have seen
tires so hard that there was no residence
to speak of and the owner might almost
have used wood or iron bound wheel,
SO far as relieving the truck from strains
was concerned If a tire has the proper
amount of residence and the proper size
is used there should be no trouble in
getting 1900 to 1900 miles life.

We're carrying over 60 per cent of the
load. This is not good practice and will
certainly tend to short life.
Urges a Tire Standard.
Il should like to see standard adopted
in common by manufacturers and users,
based on certain sizes to carry certain
weights. The Society of Automobile
Engineers has taken step in the right
direction, but should go farther, and be-
lieve it will.
The government is taking up the tire
question at the present time. and / be-
lfeve it will specify certain sizes of tires
for certain loads in future work.

see loose ends Of cable lying around the
floor, and the employe simply picks up

When the car is fully charged the cable
is thrown on the floor and left there
catching dirt and rubbish, and, worst of
all. water.
When I designed our garage we
brought all cables overhead, then dropped
the ends down. the free end being long
enough to form loop. To this loop

method we have been able to keep the
floor clear OF wires Of all kinds. and it
can be cleaned with a hose without any
danger of running the cable.
In our garage each car has a sepa-
rate charging panel. This may seem un-
usual and in public garages would prob
ably not be advisable, but the use Of in
dividual panels permits US to keep an
absolute record of the current used by
each car.
Charging Panels Numbered.
THE panels are Of the Cutler Hammer
make and on each is mounted volt
ammeter, a double pole knife switch.

which the charging current is regulated
"At the bottom Of each panel are
mounted protective devices consisting of

Each panel Is numbered. and In the
garage proper corresponding number
is hung directly over the charging cable,
so that in shifting chauffeurs each one
has only to know the number of his car.

I'VE nave also recently installed d

to keep a spare wheel on hand for each
size car. and If these wheels are kept
on the floor all the time they are very
apt to injure to some extent that part

rack is nothing more than a heavy wood
framework with pegs at proper intervals.
