INFLATION PRESSURES
The following tables present commonly found
Caterpillar and the
tire suppliers’
recommended cold
inflation pressures for tires on Cat machines. For inflation
pressures of tire suppliers not listed please obtain them
directly from the respected supplier.
The inflation pressure is based on a ready-to-work
vehicle weight, rated payload, and average operating
conditions.
Pressures for each application may need to
be varied from those shown and should always be obtained
from your tire supplier.
Pressures for all tires apply to rib, traction, rock,
deep tread, and super deep tread tires.
NOTE:
Caterpillar recommends using dry nitrogen
(N
2
) gas for both tire inflation and pressure
adjustments on all current and past production
machines.
EXCAVATORS
For complete tire data and inflation pressures, see the Excavator
section in this handbook.
