by
a
severe
impact;
however,
it is
always advisable
to
check
this
angle if
steering
irregularities
develop.
Wheel camber
usually
combined with road camber,
causes
a
wheel
to try to turn
in
the direction
of
lean,
due
to
one
side
of
the tread
attempting
to
make
more
revolutions
per
mile
than the other side.
The
resulting increased tread
shuf■e
on
the
road and
the off-centre
tyre
loading
tend
to
cause
rapid
and
one-sided
wear.
If wheel camber
is
excessive
for
any
reason
the rapid
and
one-sided
tyre
wear
will be
correspondingly
greater.
Unequal
cambers introduce
unbalanced
forces which
try to steer
the
car
one way or
the
other.
This
must
be countered
by
steering
in
the
opposite
direction
which
results
in
faster tread
wear.

HIGH-SPEED
TYRE PRESSURE CONDITIONS
During
high-speed driving and
in
competition
work, the
tyres
are
subjected
to
greater stresses
than
those produced
during
ordinary driving.
Many
factors,
some
probably
as
important
as
the
physical
characteristics
of the
tyre
itself, affect
the
speed
at
which
it
should be
driven: road surface,
air
temperature,
and
in
particular
the
duration of
high-speed driving.
However,
a
normal
tyre
in
good
condition and
at
the
correct
pressure
can
be
relied
upon
to
perform
satisfactorily
at
speeds
up
to
80 mph.
(144
km.p.h.)
and
intermittently
in
excess
of this
by
10
mph.
(18 km.p.h.).
If the
car
is
to
be driven
consistently
at
speeds
near
the
maximum
of
which
it is
capable
special
tyres
should
be fitted
on
the
advice of
the
tyre
manufacturers.
When
it is
intended
to
indulge
in
high
speeds
or
competition
work
we
advise the
use
of first
tread
tyres.
