* The inner pressure must be increased by 25%.
A short-time increase in load is allowed for 10% of the shift time max.
Note. Changes of loads depending on the speed are used in cases when the tire is not
operated for a long time at high torques. During fiel works and other conditions of long-
time operation at high torques, the values are applied corresponding to the speed of
30 km/h.
For transportation jobs on roads with hard surfaces, increase the pressure by 30 Mpa
(0.3 kgf/cm²).
When wheels are twinned, their total carrying capacity must not exceed the carrying
