frequently

and
maintained

correct
tire

it

is

possible
to

avoids

abnormal
wear
which
invites
serious

problem
If
tires
indicate

abnormal
or

uneven

wear
the
cause
of

problem

should
be
detected
and
eliminated

After

inflating
tires

leakage
in
valve

should
be

checked
Without

caps

leakage
will

occur
due
to

dirt
and

resulting
in

underinflation

is

checked
be
