CARE AND USE OF TIRES.

First of all, keep your tires up to
normal pressure. The car rides on
air, not on the side walls of the cas-
ing, and bloW-outs and rim-cuts will
result if tires are not properly in
f1ated. Also, if tires are run in a
soft condition the castings will creep
around On the rim, often resulting
inner tube. Proper imitation tables
| Tor all sizes OF tires are furnished
by the different factories, but if not
available. a good rule to follow is
20 polnds pressure for each inch OF
diameter-a 4inch tire having 80
pounds, and 4 12 inch tire 90
pounds pressure.
Don't let out any air pressure on
account of hot weather or long trips,
under the impression that the extra
heat VIII increase the air pressure
to a dangerous. degree. Heat has
very little influence on air pressure,
(pressare used in automobile tires)
and you only invite extra trouble
when you debate the tires due to hot
weather.
Fill Small Cuts in Tread.
In few minutes at night you can
clean out any small cuts with gaso-
line; apply some of the cement from
the repair kit and squeeze in a little
tire putty. This putty hardens over
night and effectually close the cuts.
Nulvanize Big Cuts or Snags.
Long cuts, tears or mud bilsters
haf0rn
should be vulcanized at once by a
competent repairman.
Unusual Wear ON Tread.
A common trouble especially hard
to account for is sudden wearing
down of the tread, either unevenly
or around the entire circumference.
This may be caused on the rear tires
by quick starting or stopping, or ON
the front by improper alignment OF
the wheels.
Chains.
If you find it necessary to use
chains, apply them loosely enough so
they can slip around the tire.
Chains that are too tight quickly cut
and tear the tire tread. If too loose
they viii fold under and produce the
same result.
Oil.
Keep tires out of grease and oil.
Oil roIs the rubber quickly and caus-
es the tire to peel off. If necessary
to drive over oiled roads, it is a good
plan, on returning, to wipe the tires
with piece of waste soaked in gaso-
line. This cuts, the oil and leaves
the tires clean
Don't drive fast around corners.
Aside from danger Of skidding, this
throws terrific strain on the tread
and carcass of the tire.
Don't let the clutch in with a jerk
or jam on the brakes when stopping.
Spinning or sliding the wheels will
quickly wear thousands of smiles of
lservice off the treads.
Don't sCrape the. side walls against
curbstones. This wears off the rub
Der. and exposes the ia brio to the air
and dit and moisture, which soon
starts to rot.
Don't drive fast across car tracks
or other irregularities in the road
surface. A sharp blow that hits the
tire squarely may break the inner
fabric emo later pinch tube or cause
a blowout
Don't leave the car standing on
Che tires for long period of time.
Don't store car where tires are ex-
posed to bright light or allow it to
| rest on an oily, greasy floor.
Don't carry spare, tires or tubes
unprotected.
Don't drive on car tracks.
Don't overload either the car or
the tires.
Dent drive on fat tire for even
hundred yards. 1t will not only
injure the casing, but will also tear
the tuDe.
Don't drive with the front wheels
out of alignment Examine the cas-
ings every few days, and if you
notice. any undue wear have the
wheel lineup checked at once.
