The aim of the article has been the study of deflection
laws in tractor oversize low-pressure tires, intended for
class 5 tractor propulsion. The research method was
experimental. The "tire tester" and specially designed
devices for determining the deflections of the inner and
outer tube relative to the rim in the circumferential,
radial and collateral directions have been used in it. A
number of factors determine outcome indices of the
wheel with pneumatic tyre. Among them the ability of
the tire to deform so that at low - hysteresis losses in the
rubber-cord casing and admissible stresses in it, based on
resource, the largest area of contact with the supporting
base has been created. This circumstance is of particular
importance in the development of tractor tires of low
pressure, deflection characteristics of which are poorly
studied at present. Analysis of experimental studies
showed the necessity of the feasibility of creating the tire
with the cord orientation in its casing so that in the zone
of perception of the vertical and longitudinal forces the
cord threads would work in a mode close to the
extension, but in the area of contact it would work in
bending. These requirements will best meet the tire in
which the cord threads are parallelly located in adjacent
layers and directed at a predetermined angle in the
direction of effect of the axial forces on the wheel in oncoming fibers
