INFLATION

Correct
tire

pressure
is

very
impor

tant
for

steering
ease
and

riding
com

fort
Correct

pressure
also
makes
for

a

quieter
ride

and
extends
tire
life

If

all
tires

are

inspected
frequently

and
maintained

at
correct

pressure

any

sharp
objects
in
tread
can
be

quickiy
detected
nd
abnormal

wear

which
invites
serious

problems
can
be

avoided

After

inflating
tires
valves

should

be
checked
for

leakage
Without

valve

caps
leakage
will
occur

due
to
dirt
and

water

resulting
in

underinflation
Ac

cordingly
whenever

is

checked
be

to

tighten
