Remolded tires (tires manufactured by remolding new tread and sidewall rubber to a used tire carcass) have been the subject of an investigation with respect to the applicability of Transport Canada safety standards.
Transport Canada recently clarified, by defining a retreaded tire in Technical Standards Document #119, that remolded tires are not retreaded tires. As such, remolded tires are considered newly manufactured tires and must meet Transport Canada tire safety standards.
