Tyre Sizes and Pressures
Introduction
The maximum pressure marked on the tyre may be
different from the pressure shown below. Inflate the tyres
to the pressures shown below. These pressure are agreed
with the tyre manufacturer/s in accordance with the
European Tyre and Rim Organisation (ETRTO) standards
to satisfy machine stability performance.
Note: If the tyres fitted to your machine are not shown,
then contact your JCB Dealer for advice, Do not guess the
tyre pressures.
Always check the tyre pressures with the machine in an
unladen condition.
In special conditions (for example on sand) the air
pressure in the tyre may be reduced, refer to your JCB
Dealer or tyre manufacturer.
Specifications
The pressures are based on a standard specification
machine with:
– A maximum towing speed of 25mph (40kph), a
different countries legislation can specify a lower
speed.
– An average loading cycle speed of 6mph (10kph).
Refer to the tyre manufacturer for:
– The pressures for non-standard machine
specifications or work applications.
– Earthmover tyres, the maximum distance the
machine can move in one hour without overheating
the tyre.
– Pressures with non-factory installed tyres.
