tire. but depends rather upon the de-
sign, quality, and usage. No good tire
OF any standard type will be cut by any
standard rim, II properly used. On the
other hand, any type OF tire will be
injured IL subjected to abuse. Under
i imitation, dented and irregular rims.
excessive loads, tire filters and stiff re-
liners are the common causes for cut
ting and breaking above beads.
The flanges Of rim may be battered
tire debated for a considerable dis
tance; the next tire applied Is sure to
be cut above the beads.
Tires carrying heavier loads than
( those for which they are designed may
develop breaking at the beads where
engaged by clinohes of the rim.
! II rims become rusted from water
working around the beads when tires
are run soft or through neglected cuts
In the tires. or from neglect 70 put
proper fittings on the valve stem, the
rust should be removed with emery pa
per and the rims painted with coating
of aluminium, graphite and OIL, or
other good preservative solution. when
applying a tire, be careful that the mop
does not slip underneath the bead and
crowd 1t in clinch of the rim.
Rims of Wrong Size.
Under the impression that they are
oversize, II is not uncommon for tires
to be applied to rims of wrong size
for example. using 36x4h tire on
36x4 rim. The diameter of this rim
is approximately % Inches ana the

er thing, the 4A-inch beads are not
constructed to ft 4-inch rim and
clinches. Good results cannot be Sc
cured when the beads are strained
and crowded in this manner. The
correct oversize tire for 36x4 rim is
37x4h.
In some instances, 3Sx5h tires have
been fitted to 36x412 rims. The diam
eter of a 36x4h inch rim seat and the
diameter of 3Sx5 " beads are the
same. approximately 81 inches. hut
the rim cross section in the cllnches
is not suitable to accommodate the
beads of " inch cases-rim cutting,
pinched tubes and unsatisfactory
service will result.
When removing tires from rims do
not overlook pushing the valve stem
of the tubes up far enough In the
tires so that II will not be necessary
TO pound the fastening device of the
rims in order to release the beaos ol

ed from pounding them in this way.
When chafing, cutting or breaking

sides, repairs are expensive and no.
to be recommended. If the injury
only extends for a short distance over
one or both beads. a skillful repair
man can make a good job at rea
sonable cost.
Tires Ridden Debated.
Running a tire. debated. for any great
distance Is harmful and lneXcusable
When travelling at very high rate OF
speed, it may then, of course. require
some little time to bring the car to a
stop. A soft or fiat tire on a front
wheel can always be noticed by the
difficulty in steering the car in q
straight course; the steering wheel nat
urally favors the side of the fiat or soft
tire. II on a rear wheel, pounding ano
humping will be noticeable.
Demountable and quick detachable
rims make 1t possible to change tires
equipped, 1t is wise to stop and give
the tires attention when needed. Dam
age to the side walls, beads, fabric in.
side, also the inner tube usually makes
1t difficult to execute practical repairs.
A rear tire ridden debated veiy faI
may result in damage to the dineren
tial of the car.
Driving In Car Tracks.
Rough streets tempt one to drive il
car tracks. 1t is more comtortabl,
for the passengers and may be econo

bumps and unusualNyibration by run

rough, cobblestone pavements, and tn,
tires won't be injured noticeably b!
doing this occasionally; 1t Is the con
tinued practice that shortens the mile
age.
Quite often the pavement along in
side edges of rails is very rough anC
may result in cuts to the rubber anC
bruises to the fabric. Driving owe
street car track switches at the point
ed frogs may cut the tires seriously
Rails on hills are to be avoided a.
much as possible, as they usually hav,
sharp, thin splinters on the edges
which are liable to cut or punctur,
the tires,
be careful when driving on wet rails
quick twisting of the front wheels ma,
result in. accident from the rear o
the car, skidding sidewise when leaving
the rails.
Edges OF the rails wear away tn

usually develop breaks inside. 1t !
