Radial
tire performance is now denoted
by
a
Load Index and Speed
Symbol
replacing the
Ply
Rating commonly found on cross
ply tires. Figure
1 shows typical markings
to be
found on
the
side
wall of radial ply tires.
NOTE: All tires fitted to Ford tractors have a
Speed symbol 'AB' and are therefore suitable for
speeds
up
to 25 MPH (40kmlh).
The
maximum load that may
be
carried
by
the tire
is dependent upon the
Load
Index shown on
the
side wall. In
the following charts
the
loads given
are for individual tires operated at
speeds
up
to
19 MPH (30
km/h).
The right-hand
(shaded)
column indicates the maximum load at speeds up
to
25 MPH (40
km/h).
