5.17.8 - Table of
radial loads and standard inflation pressures
*
Consult the tyre manufacturer for loads under 12 psi
(80 kPa) pressure.
NOTE:
1. The bold figures represent the maximum load for the
symbol indicated (*, **, ***).
2. For transporting purposes, the tyre inflation pressure
can be increased by 30 psi (210 KPa) (consult the tyre
manufacturer for this minimum transport pressure).
This increased inflation pressure must be decreased to
the nominal value before the tractor is removed from
the transport vehicle.
3. For dual wheels, the loads to the tyres must be
reduced. Multiply the figures in the above table by 88.
4. For the above tyres, which are intended for a cyclic
load without long periods of use at high torque or at
speeds exceeding 8 kph, the above values can be
increased by 70% (inflation pressure is increased by 40
KPa (6psi).
5. For FIELD WORK at high torque (ploughing for exam-
ple), the basic loads can be increased by 7% PRO-
VIDED THAT THE TRACTOR TRANSPORT SPEED IS
LESS THAN 32 kph.
6. For transport purposes and during operations that do
not require long periods of high torque, the following
load limits at variable speeds must be applied without
modifying the inflation pressure.
IMPORTANT: Because the size relationship between
the front and rear tyres is very important on 4WD trac-
tors, only compatible sizes should be used - see sec-
tion 6.14 - TYRES.
