This patent describes a process for manufacturing char and hydrocarbons from discarded used tires. The process consists of: introducing the substantially whole tires into a reactor; pyrolyzing the substantially whole tires in a reaction chamber continuously at a temperature and pressure and for a reaction time sufficient to cause the tires to dissociate into a vapor and a solid phase; the pyrolyzing step including directly heating the tires with a radiant heat source at temperatures of 1000{sup 0} to 3000{sup 0}F; producing char from the solid phase; and processing the vapor phase to produce hydrocarbons.
