Hills
•
If momentum is too slow for wheel speed, the
result is lost traction and the wheels spin.
•
If momentum is too fast for wheel speed, that
also results in lost traction and the vehicle skids.
•
If the momentum is in tune with wheel speed,
you have traction and good control.
Tires
when climbing a hill,
momentum and traction
are your friends.
however, you
call the shots.
remember…
going uphill, the
more momentum
you have, the
less traction
you need.
it’s a good
idea to let the
vehicles ahead
of you make
it to the top
first.
then you won’t
have to stop
half-way up.
and remember
to keep your
distance!
get a running
start so when you
reach the peak,
you’ve got enough
momentum left to
get you over.
try to get to the
top of the hill in
one smooth unin-
terrupted run.
keep tires
properly inflated
and in good
condition to help
traction.
distribute loads
evenly and place
partial loads over
the rear axle.
avoid poor
driving, like
quick starts,
sudden stops
and sharp
turns.
they cause
you to lose
traction.
and use
tire chains
if you need
them.
tire chains improve
traction on ice and packed
snow, but
only
if they
are installed properly
and cleaned regularly.
chains that are
packed with ice
will lose their
effectiveness.
