EXAMINATION OF TRUCK TIRES AS TO IDENTIFICATION OF DAMAGES WHICH ARE FORMED AS A RESULT OF OPERATIONAL TIRE WEAR OR PRODUCT DEFECT

Abstract

The sequence of carrying out of researches of tires of a freight vehicle on the basis of expert practice is considered. The research of tires of a truck has been conducted, an example of an expert research of tires is resulted, as a result of which the causes of damage of tires were established. The tire connects the vehicle to the road, perceives its weight, braking effort and dynamic impact that arises due to the roughness of the road surface. It is not uncommon for the vehicle to operate even on roads with a satisfactory road surface and damage to the tires. Damage to the tires can be generated as a result of industrial damage (factory defect) and as a result of operational damage. The most common and serious cause of premature wear and damage to tires is non-compliance with the established air pressure norms and overload tires. Changing the configuration of the profile and increasing the deformation of the bus cause an increase in the voltage in its material. As a result, it increases its premature wear. At increased load (overload) the tension voltage in the places of contact of the tire with the road increases and its specific pressure on the road, from which the tread wears away more quickly. Overvoltage in the material and increase in deformation is accompanied by a general increase in friction and heat formation in the tire. At increased load (overload) the tension voltage in the places of contact of the tire with the road increases and its specific pressure on the road, from which the tread wears away more quickly. Overvoltage in the material and increase in deformation is accompanied by a general increase in friction and heat formation in the tire. In the course of the research it was established that the tires Satoya SD 062-III have operational damage, the detects damage to the tires was formed as a result of their operation, which could contribute to vehicle overload, non compliance with tire pressure and the movement of the vehicle on roads with improper road surface. External inspection the examination of Satoya SD 062-III tires showed no signs of industrial damage (factory defects).
