6.8.3. Pneumatic Tyres Use and Care
Keep to the basic rules of pneumatic tyres
handling and servicing, namely:--
а) follow carefully recommendations on
inflation pressures in tyres (refer to Ta-
ble 4);
b) avoid operation with substantial slip-
page of the driving wheels; strictly fol-
low instructions on admissible combi-
nations of front and rear tyres for trac-
tors equipped with a FDA (see Tables
5
а, 5b);
c) in case of irregular wear of tyre tread,
switch tyres regularly from the right- to
left-hand side, and vice versa;
d) observe the instructions for tyre
mounting and dismantling;

For tyres with ply rating 6 and above, the inflation pressure of tyre should be increased by 25%.
When employing tyres with ply ratings 6 and above on front-end loaders, an increase in load per tyre
of up to 100% is a normal practice when working in the loading duty, only.
