The thesis deals with a problem of tyre durability at cyclic fatigue. There are several factors that affect the durability of a tyre. These factors have been indentified and evaluated on the basis of dynamic and static tests. First, a design of a radial tyre, the characteristics of its components and mechanisms that affect its durability were presented. Then values at static tests and rolling resistance were measured and cyclic fatigue at high velocity and durability tests was evaluated. It was established how load, pressure and velocity affect the tyre rolling resistance and consequently tyre durability.
