Analysis of Truck Tractor Tire Damage in the Context of the Study of Road Accident Causes

There are many accidents in road traffic involving both heavy goods vehicles and passenger vehicles, the interpretation of causes some can be very difficult. The paper presents results an analysis accident a truck two cars. hypothesis was verified that incident took place after damage to front wheel truck, which resulted uncontrolled change direction its travel leaving lane opposite damaged tire inspected, traces were described form cracks on side surface, irregular abrasion central part surface near bead, as well deformations resulting from cord. thesis made cracked result material structure defects. In order verify it, bench tests carried out deformation sidewall at various load conditions, simulated driving with too little air pressure tire. Detailed studies fracture wires make up steel cord out. Macroscopic examination eight samples revealed presence corrosion changes should not occur under normal operating conditions. research work indicate rupture caused by delamination coatings wires. These defects could have arisen due earlier cracking rubber layer ingress moisture or use corroded production. analyzed case, driver regain control vehicle avoid collision oncoming vehicles.
