NOTES 1: For tires used in dual service, above tire load limits must be reduced. Multiply figures in the above table by .88.
2: The load ratings in the above table reflect a different operating duty cycle when compared to agricultural tractors. This cyclic service is intended for use on a vehicle with a minimal requirement for torque transmission and with appreciable total weight fluctuations; e.g., combine grain tanks that are repeatedly filled and emptied. Unloading is to occur before off-field transport.
3: For log-skidder tires with the same size and ply rating, the above cyclic and road transport loads can be applied.
4: For intermediate inflation pressures and for tires not shown, the field service loads in Table E may be increased by 87% for 6 mph (10 km/h) applications and 70% for 10 mph (15 km/h) applications with a 30% increase in inflation pressure. Consult tire manufacturer for loads for pressures not shown for transport service.
5: The above road transport loads apply to all speeds up to and including 25 mph (40 km/h).
6: Due to the higher inflation pressures specified for these tires, the tire and wheel manufacturer must be consulted.
7: The above field service cyclic loads only apply to vehicles that operate up to an 11° slope (20% grade). For operations on slopes greater than 11° (20% grade) loads in Table E shall be used.
8: For tires used on grain carts, the field service loads in Table E may be increased by 70% for 15 mph, up to one mile, with a 30% increase in inflation pressure.
