Sometimes a grinding noise OF this

the bearings Of the wheel. the brake

the trouble lies there. In turning

Motor Department. have heard
quite some arguments for and
against the wire wheel. I am unde-
o;ded whether to use wire wheels
this year or not. am told that wire
wheels ara more economical on tires.
VIII you please tell me why this is?
Is IL because the wire wheel Is not
so solid as the wooden wheel?
Thanking you for this information in
advance. I am, +. S
II Is true that the wire wheel is
more resilient than the wooden
wheel. One OF the principal fea-
lures In favor OF the wire wheel is
that Il relieves the tire from excess
sive heat. The tire is IN direct con-
tact with the metal rim. which is en-
tirely exposed: likewise the wire
spokes serve as an additional source
for heat radiation. a tire used on a
wire wheel will run at a much lower
temperature than that on a wooden
wheel. Since heat has a great de-
teriorating effect on rubber, you can
readily appreciate wherein this fac
tor alone will determine tire wear.

freeze at zero. A forty per cent solu-
zion will show 0.954 and freeze at
20 degrees below zero. You should
use a hydrometer for testing.
Motor Departmental have a 1916
Briscoe touring car While trying to
start In the snow I noticed that only
the right rear wheel turns, while the
rear left remains stationary. As last
summer I broke two axles on the
rear wheel. both breaking in the
dinerenttal. about two inches from
the end, I wish you would tell me IL
my car drives from one axle only.
and II so. II IL is supposed to- The
machine runs all right in every 9TH

All cars drive through the differ

tial should equalize the driving. and.

Motor Departmental mag
neto on my car is bolted to the
crank case and to the touch gets
very hot when on the road. Should
this cause any trouble? How much
heat will the magnetic stand?
H.F.
Overheating the magnetic will de-
magnetic them, but the heat which
reaches the magnetic in your case
IS hardly injurious. II there is suffi-
cient heat 20 affect the magnetiza-
ton OF the magnets. this would also
affect the fabrication Of the bearings
OF the magnetic. In your case how
ever. there seems TO be nothing ser
ious There is not much danger 10

erage engine. In motor design IL is
customary 70 avoid the exhaust pipe.
