do not permit tractor operation and parking on damaged and blown-out tyres;
do not permit travelling on tyres with decreased internal pressure even for small dis-
tances as it leads to tyre failures;
in order to avoid increased wear of tyres, operate the tractor on roads with hard
pavement for 30% of the total period of operation max;
protect tyres from the ingress of fuel. oil and other oil products thereon;
do not admit tractor operation with internal tyre pressure not corresponding to the
prescribed standard for specific case of its use;
adjust the tyre pressure value when tractor operation conditions are changed, since
pressure change impacts the tractor operation properties and efficiency.
CAUTION!
When working with significant traction forces, a slippage against
tractor sides may be observed. It can be remedied by increasing pressure in the
tyres, however the traction force reduces with that.
