General texts for the graphs and tables

  1. It is recommended not to exceed the maximum tyre pressures shown in the tables.
  2. The dimensions indicated, which apply to a nominal tyre pressure, may vary in practice under the influence of actual tyre pressure and conditions of use.
  3. When mounting tubeless tractor tyres, we recommend a TR 615 A valve.
  4. Inner tubes for implement tyres are fitted with TR15 valve, with the exception of 550/60-22.5, 600/55-22.5 and 700/45-22.5 on standard rim with TR218 A valve or detachable valve.
  5. TL = Tubeless, TT = Tube type.
  6. 100kPa = 1.0 bar, 100kPa = 14.50 PSI

Load capacity information

Implement Tyres
Low load variation (LLV and High Load Variation (HLV)
In the case of diagonal implement tyres a distinction should be made between applications in which the load per tyre fluctuates greatly and applications in which the load per tyre is more or less constant. If the load varies by a factor of 2 or more between the non-laden state, we speak of High Load Variation. Where the differences are smaller, we speak of Low Load Variation. For HLV applications, the load capacity per tyre may be increased by 20%, while the tyre pressure must be increased. Examples of HLV applications are self loading trailers and muck spreaders. Examples of LLV applications are tillage machines and towed mowing machines.

Driven/Non-Driven Wheels
If implement tyres are driven, the load capacity is 70% of the value stated.

Tandem Axels
Where implement tyres are fitted on rigid tandem axels, extra lateral forces occur during sharp turns on the road. For that reason we advise maintaining a reserve of 20% for the necessary load capacity of tyres on rigid tandem axles.

Ply Rating
Most diagonal implement tyres are given a ply rating. The weight capacities figures relates to the tyre being used under LLV conditions.

Tractor Tyres
Double Fitting
If driven wheels are fitted as twinned wheels, the load capacity per tyre is equal to that of one in single fitting, reduced by 12%.

Agricultural work with a high drive torque
If during work, such as ploughing, a high drive torque is required of the tyres, the load capacity with the same tyre pressure will be reduced. The H.T (High Traction) line for these applications applies to all usual field speeds (20 km/h and lower).

Transport Work
For intensive road transport at more than 30 km/h the tyre pressure of radial tractor tyres should be increased by 40 kPa (0.4 bar).
