OVERSIZE TIRES ARE
A DISTINCT ADVANTAGE
Majority of Cars Are Overload
ed. Either with Equipment
or PASSENGERS.

tachng to the use of diversified tires on
motor cars is the contention Of f. l.. Rey-'
nolds, one of the experts OF the big Good
rich Company in Akron, Ohio. major
lty OF cars, he says, are used under alb
normal conditions at some time or other
and, no mater how infrequently, such
stress will adversely affect tire equipment
unless there is a margin OF safety.
There is not the slightest doubt that Il
ideal conditions for the use of the original
equipment of any automobile were fol-
lowed, there would be no necessity for
diversified tires" Mr.. Reynolds says.
THE manufacturer OF a car after due
consultation with the manufacturer OF
the tire, selects an equipment which Is
quite sufficient for the car as delivered
by the manufacturer, with the presump-
ton that the specified number Of passen-
gers of average weight will be the most
the car will be required TO carry, but when
/ the user Of the car makes his purchase
one of the earliest things he does is TO
provide one or more spares. which most
! frequently than otherwise he hangs on
| the back of the car. Not infrequently he
| adds one or two extra TO the number OF
| passengers designed to be carried In the
car. Here, because of extra weight, is
! the first demand for a somewhat larger
tire.
! Again, the diversified tire has a thicker
tread. The ordinary unexpected damages
10 which a car is subjected will. as a mat
/ ter OF course, not affect the diversified tire
quite as seriously as the regular tire be-
cause the thicker tread naturally means
1fegIf le.f gaG ar. m n fell
less penetrating.
| 1.-THE thought of the average user OF an
automobile is that occasionally overload
ing car does not injure the tire, and
that II is necessary TO continue 10 use
the car overloaded in order TO have any
bad effect. This is not true. a five-mile
drive with this excess weight I'm the car
may start a deterioration that will con-
tinue OF itself without any outside ac-
celebration until the tire has become use
less much quicker than is expected OF IL.
1.-The building of tire Is Of such
character that an unusual and severe
| strain for even short period OF time
may cause the plies OF fabric to separate
or break some few threads in one ply OF
fabric, so that the action Of the part In
itself will advance deterioration much
more rapidly than ordinary service
IAN additional advantage In diversified
tires is the easier riding qualities a car
equipped With tires that are required to
perform up to the limit OF what is eH-
pected of them must be inflated up TO
the limit prescribed by the manufacturer
OF the tiresi in order TO give the maximum
amount of service. A tire that Is carry
ing much less in weight than the pre-
! scribed capacity can be much less fuzzy
inflated.
II recall very clearly a car weighing
$3.50 pounds which was equipped with
36x4-inch tires by the manufacturer
which gave, according TO the equipment
An excess of 100 pounds without load. The
users Immediately removed the S6xf tires
and replaced them with 37xiR tires, which
had a carrying capacity OF 400 pounds
| After the car was provided with spare
tires. robes, blankets, fuel, OIL etc. the
car was weighed and found to weigh $500
| ,ounds IL is a four-passenger car, but IL
not infreouently carries Ave passengers.
"While the imitation prescribed by the
,oenufacturer of the tires would require
for the 4-lnch tires 70 pounds of air. the
user has ridden the car on 4Iz-inch tires
with 10 mounds of air, and the rear tires
AVERAGED up to 5000 miles and the rroht
tires over $50. o,,
."This practice would prove much
more satisfactory advantage WIN the
oversized tires, inasmuch as the car mas
been used practically altogether on CITY
streets out OF the 5000 miles accom-
plished. probably not over LOO were on
country roads. Part Of the time was
during a factory strike, when the streets
we're well strewn with glass, nails JACKS
and other matter that would De caIcu-
lated 10 injure the tires.
"Twice during the time the tires were
running the owner had repair shop 30
over all the small cuts and seal them up
which he regards as no more extraoroi-
nary care of tires than having clothes
pressed at frequent intervals III order -
get the best service out Of them
"If the owner OF car starts out VITA
the theory that he purposes to drive on
air that in order to ride he must have
air that in order 10 have air he must
keep the air receptacle whole, and III
order 10 do that must see that the cover
ing has reasonable care and considera-
ton. he will get satisfactory service from
1 the tires, provided he does not ASK more
