Computational Research of Low Profile Special Purpose Tires

The vast majority of wheeled vehicles and modern cars are equipped with pneumatic tires. There is a wide range of tire designs of different sizes, both of domestic and foreign manufacturing. There is a good variety of commercially available domestic tires, but the range of low profile tires with adjustable internal pressure (including all-terrain tires for military vehicles and multi-purpose vehicles) is poor.  Increasing the width of the tire profile makes it possible to reduce the mass of the tire and internal rolling losses. It also improves vehicle handling and stability; and increases the maximum permissible speed of the tire. The use of tires with low profile allows enlarging the space for arranging the wheel-hub drive, brake and suspension system components. This study examines 16,00R20 and 445/85R24 tires with the same dimensions. The authors compare the intensity and nature of deformation in these tires, and evaluate the temperature distribution on the tire profile and the design endurance when the vehicle is in motion. The analysis of the results obtained leads to conclusions about the effectiveness of using low-profile tires instead of full profile tires.
