From an economical point of view, a significant effect is achieved when retreaded tires are installed on vehicles, instead of new ones. With the retreading process, the "spent" treading layer (up to the depth determined by the legislation) can be replaced by a new one, if the supporting/basic structure is preserved, thus prolonging the period of their exploitation. The cost of retreaded tires is approximately 50% of the cost of new ones, which certainly represents significant savings for transport companies, especially when considering the fact that the tires of commercial vehicles can
be protected several times. The purpose of this paper is to consider the use of retreaded tires as an alternative solution to the replacement of the used (and unusable) tires to the new ones. Respecting the economics effects, this paper aims to help (large transport companies) in making a decision on the application of retreaded tires, with a special emphasis on safety aspects in their use, particularly for commercial vehicles. The results of analyzes discussed in this paper show that retreaded tires are not the cause of traffic accidents, which can result in significant positive economic, ecological and other effects in their exploitation, especially in fleets with a significant number of commercial vehicles.
