Highlighted row indicates cyclic high load variations. 1) When tire equip vehicles subject to haulage cyclic high load variations excluding
transport applications on long distances, i.e. vehicles used on round trips (e.g. from field to farm) where on one way the vehicle is
empty and on the other way the gross vehicle mass exceeds two times the mass of empty vehicle (last two rows in the table). 2) When
fitted on tractor steering wheels load capacities are 80% of free rolling and inflation pressure 20% higher. 3) For 10km/h and stationary
use inflation pressure raised 20% and 25%. 4) Load for intermediate speed should be taken as an average between two close speeds.
5) Load at lower speed than 10km/h may be similar to the load for 10km/h.
