Tire
inflation

Correct
tire

is

very

to

ease
of

steering

riding
comfort
This
also
reduces

driving

sound

to
a

it
is

possible
to
detect

Also
the

avoids
abnormal

which

invites

If

the

Tires
of
radial

ply
construction

will
revolve
with
less

camber
thrust
force
and
with

greater

cornering
power
on

turns
This
tends
to
cause
local

on

Exercise

special

for

during

Note
a
Radial

ply
tires

should
not
be
mixed
with

ordinary
tires

since
their
characteristics
differ
from

those
of

ordinary

b
The

should
