It is a 7 axle line modular trailer combined with an extendable 11m long vessel deck. The distances between the padded heads and the side wall of the vehicle should be equal and in the range of mm when the vehicle stands on the horizontal tilting platform. All axles of the vehicle should be fixed, the spring system blocked The tilting shall be done very slowly, until the unstable position of the vehicle.

The aim of this study: to investigate how tire deformation in a multi-axle truck changes by changing the air pressure in the tires and load distribution.

For research, a multi-purpose truck SISU E13TP was selected. Tire pressure varied from kPa to kPa. The load was loaded in the center of the truck and at the rear of the truck.
