SECTION 3 -- FIELD OPERATION

TYRE PRESSURES AND PERMISSIBLE LOADS
Radial tyre performance is denoted by a Load Index
and Speed Symbol replacing the Ply Rating
commonly found on cross ply tyres. Figure 239
shows typical markings to be found on the side wall
of radial ply tyres.
NOTE:
Radial tyres will have a speed symbol of ‘A8’
and/or ’B’which identifies the maximum speed rating
for that tyre. Tyres marked with the A8 symbol are
suitable for speeds up to 40km/h (25 MPH), those
marked with a ’B’ symbol may be operated at speeds
up to 50k/mh (31 MPH).
The maximum load that may be carried by the tyre is
dependent upon the Load Index shown on the side
wall. In the following charts the loads given are for
individual tyres operated at speeds up to 40 or 50 km/h
(25 or 31 MPH). The two right--hand columns indicate
the maximum permissible load
per tyre
at speeds of
40 or 50 km/h (25 or 31 MPH).
WARNING
When operating at high road speeds, tyre pressures
and maximum load capacities advised by the tyre
manufacturer should be strictly adhered to. Consult
your authorised dealer or tyre supplier for the correct
pressures and loads for the tyres fitted to your
tractor.

IMPORTANT:
The above table provides an example of the maximum load limitations that occur at various tyre
pressures on a representative range of rear tyre sizes available for your tractor. These figures are
per tyre
and
should be used for guidance only. For exact information regarding inflation pressures and loads for your particular
tyres, consult your authorised dealer.
