Recommended Inflation Values Of The Rear Wheel Tyres - Zetor FORTERRA HSX 120 Operator's Manual

RECOMMENDED INFLATION VALUES OF THE REAR WHEEL TYRES

The value of the permitted load-bearing capacity of the rear axle must not exceed the sum of the load-bearing capacity values of
both the tyres that are installed on the axle. The values of the permitted load-bearing capacity of the axles are specified in the
"Main technical parameters" of the corresponding tractor type. On the same axle of the tractor there must not be tyres of different
dimensions and designs (in this case tyre design means the diagonal or radial tyre version).

Note: The 480/70R38 tyre is a dimensional equivalent of the 16.9R38 tyre.
The 570/70R38 tyre is a dimensional equivalent of the 18.4R38 tyre.
Inflate the front as well as the rear tyres to the lower of the above mentioned values for field work on light soil (dry, sandy).
The higher of the above mentioned pressure values is designed for work on heavy and compact soil. During ploughing
work at the minimum inflation value there must not be any folding of the side parts of the tyres. The load-bearing capacities
specified in the tables correspond to the maximum travelling speed of the tractor, i.e. in the case of radial tyres 40 km/h
and in the case of diagonal tyres 30 km/h. The specified values refer to one tyre. For a tractor the max. load per axle must
not exceed the max. load-bearing capacity values of the tyres.
