Consider the scope of the pneumatic tire. Presents special requirements for pneumatic tires for construction machines. A patent search is conducted on the different test stands for pneumatic tire. Two groups of test benches are considered: the stands allowing to measure the concrete parameters and stands intended for increase in accuracy, or for bigger automation of measurement of parameters of a pneumatic tire. Advantages, disadvantages and distinctive features of test benches are presented. Considered the notion of norm ply-rating, the schedule of dependence of carrying capacity on ply-rating of pneumatic tire of enhanceable passableness is constructed. The method of modeling of loading capacity of the pneumotire based on cutting off of contact of the tire from a cover is presented. Concepts of carrying power of a wheel, vertical force of the bearing framework of the autotire, a spot of contact of a pneumowheel are considered. The task of general durability of shell of tire is solved by the method of sections. The most dangerous sections of a pneumocover are considered. The concept of normal pressure is considered owing to what it is established that discrepancy of internal pressure of the autotire to norm results in uneven wear of the tire and according to deterioration in operational properties. The effort in threads of a cord and explosive pressure is calculated. Dependence of loading capacity on air pressure in the autotire is considered. The relation of normal pressure to potentially maximum pressure in the autotire is calculated. The question of a possibility of increase in loading capacity due to achievement of big pressure in the autotire is raised.
