Speed Radius Index (dynamic rolli ng radius): It is used only when calculating the theoretical tractor speed according to the
ECE/EC---classification.
Always contact your dealer to ensure the right ratio is used. When track widths are adjusted or larger tyres fitted, the turning
angles have to be checked/adjusted with max turning angle of the front axle on both sides.
IMPORTANT: With larger tyres and the suspended cab (extra equipment), the space between the mudguard and the tyre
may become too small (under 25 mm) when the cab moves down. Note this especially when using the chains. Then adjust
the mudguards to suit.
IMPORTANT: On the traffic tractors 50 km/h the tyre loadings are smaller. Check from the tyre manufacturer’s catalogue.
