Conditions In Which They Can Always Be
Used to Advantage,
! A prominent manufacturing concern
has instituted a series of experiments
lately to find out the conditions under
| which the broad and narrow-tired
wheels could be used to advantage. In
the experiment TO ascertain the differ
ence in draft between wide and mar
row tire upon grass sod, the figures
! arrived at were:
| Weight OF wagon and load ...,.... 4, 500 pounds
Draft to start load with in-inch
| tire, cutting into sod ~ inches
Deep. OBSERVATION-DISCLOSURES. ....l2oO pounds
| Draft to move at dead pull ........ $50 pounds
! Draft to start same load on good,
| hard roads. .......,......... $50 pounds
| Draft to draw load on good, hard
roads. Observation-Disclosures. $50 pounds
| Draft with tire inches wide on
same sod. ...........,.............i 1900 pounds
| Draft to move load at dead pull
same sod. ....t........,....... Dol pounds
| Draft to start load with S-inch tire
on hard roads. ................... 100 pounds
Draft to move at q dead pull on
| hard roads OBSERVATION-DISCLOSURES. 800 pounds
Draft at a dead pull ON hard pave

Another experiment was with four
inch and Observation-Disclosures tires
respectively on block pavement, good,
hard, sandy road, good, level, gravel
road, and in each soft and deep mud.
The conclusions arrived at by the
committee were:
/. On hard roads, block pavements
and other permanent and substantial
roads, there is no argument, so far as
actual draft is concerned, in favor OF
the wide tired, the effect being rather
against the wide tire.
2. In their effect upon hard roads,
the wide tire have the advantage, and
that this benefit is not sufficiently ap'
preciated by turnpike and macadam
road companies.
3. In soft mud, slush, and under sim
liar circumstances under which even
the wide tire cuts in, the advantage Is
against the wide tire and in favor OF
the narrow.
4. On soft sod and soft ground
where the wide tire does not cut in
and the narrow does, the advantage is
on the side of the wide tire.
5. In loading team, draft of Csc
pounds steadily applied is as much as
should be expected for days work
and that on soft sod this may mean
when a dead pull has to be taken, ar
increase in the draft Of 1900 pounds.
6. The difference in the latter cast
between the regular draft of $50 pounds
and the increase of 1900 pounds il
equivalent to an addition Of 4,9S'
| pounds to the load
T. Or, in other words, the draft o
the load being $50 pounds may be con
sidered as equivalent to load of 49s
pounds, and the difference from tn,
steady draft of the load in fair mo
ton, and that of the same load started
at dead pull, is equivalent to doub
ling the load.
The committee closed their repor
with: 1--WE advocate wide tire 70
farms, and narrow tire for good road
and pavements."
Experiments at the Utah experiment
station demonstrated that a givel
load on 11S-inch tire drew 4l.6 per cent
heavier than when on a 3-inch tire
the draft being on fairly stiff gras
sod; on moist but hard road the / x
inch tire drew 1877 per cent. heavie
/, tn an the 3-inch.
