For tires with ply rating 6 and more internal pressure should be increased by 25%.
When using tires with ply rating 6 and more on front loaders, increase of load on tire is
allowable up to 100% only in load mode.

* Inside pressure should be increased by 25%.
Short-term change of load (not more that 10% of total shift time) is allowed.
Note: Change of load depending on speed is used in cases, when tires are not loaded for
prolonged time at high torque. During field works and under other conditions of prolonged
operation at high torque, values that correspond to speed of 30 km/h are used.
When executing hauling operations on the roads with hard surface increase pressure by 30 kPa
(0,3 kg/
с
m2)
When doubling wheels their total load capacity should not exceed the load capacity of single tire
more than 1,7 times as much.
