Note: The 380/70R24 tyre is a dimensional equivalent of the 13.6R24 tyre.
The 420/70R24 tyre is a dimensional equivalent of the 14.9R24 tyre.
The specified load-bearing capacities of tyres for field work and road transport correspond to the maximum
travelling speed of the tractor, i.e. in the case of radial tyres 40 km/h and in the case of diagonal tyres 30
km/h. The specified val-ues refer to one tyre. For a tractor the max. load per axle must not exceed the max.
load-bearing capacity values of the tyres.
Recommended inflation values of the rear wheel tyres
The value of the permitted load-bearing capacity of the rear axle must not exceed the sum of the load-
bearing capacity values of both the tyres that are installed on the axle. The values of the permitted load-
bearing capacity of the axles are specified in the 'Main technical parameters' of the corresponding tractor
type. On the same axle of the tractor there must not be tyres of different dimensions and designs (in this
case tyre design means the diagonal or radial tyre version).
