Tires are an important component of automobiles that maintains the movement direction and ensures the transmission, load capacity and smooth movement of the vehicle. To ensure the automotive active safety, a special attention should be paid to the tire durability evaluation. This article presents a research on determination of deformation grade of automotive tires using ANSYS software. It is based on QCVN 34:2017/BGTVT technical regulation on endurance test of pneumatic tires for automobiles. A finite element model is established, consisting of two components in contact: an ideal drum surface with a diameter of two meters, and a rubber tire. The air pressure in the tire follows the regulation and the drum applies on the tire a force of 80 % the permissible load. Calculation results for a specific tire in Vietnam suggests that the durability of the tire is satisfied, since the difference between the deformed and undeformed diameters of the tire is less than 3.5 %, as stated in the regulation.
