Tyre Pressure - Hardi COMMANDER TWIN FORCE Series Instruction Book

Tyre pressure

Tyre pressure depends on the actual axle load, tyre size and the actual speed of the sprayer. This means that it is often
not possible to drive fully loaded sprayer at maximum speed when having narrow wheels mounted. Be aware of specific
datas for your sprayer.
Note that not all the tyre sizes in the chart will apply to your sprayer.
