It is noted that the transition of the absolute majority of peat mining companies to the use of tractors and machines on pneumatic wheels has identified a pronounced problem of passability of equipment on soils with reduced bearing capacity. One of the ways to solve this problem is to double wheels to increase both the perimeter and the area of the wheel contact with the peat deposit. It is emphasized that for a reasonable «retrofitting» of all machines it is necessary to correctly calculate the loads on the twin wheel arrangement. At the moment such methodology is very approximate and conditional, implying equality of loads on both wheels in the block. At the same time the experience of pneumatic wheeled vehicles operation, especially on paved roads, shows that inner wheels wear out much faster than outer wheels, and this indicates greater loading of inner wheels. The methodology for approximate calculation of loads on both wheels in the block confirming this conclusion is presented.
