٭ For tyres with ply-rating 6 and more, inner pressure shall be increased by 25%.
When using tyres with ply-rating 6 and more on front lifts, load increase of up to
100 % per tyre is allowed only in loading mode.

٭ The inner pressure shall be increased by 25%.
Load variation is allowed shortly, for not more than 10 % of the shift time.
Note. Depending on speed, load variation is applied in cases, when the tyre is not
subjected to long-term operation under high torques. When performing the field
works and under other conditions of long-term operation at high torques, the values
corresponding to 30 km/h speed shall be applied.
When performing the transport works on hard surface roads, increase the pressure
by 30 MPa (0.3 kgf/cm

)
