ABSTRACT:
A flexible, integrally formed elastomeric matrix is formed using an internal mold such as an inflated tire or carved or molded rigid facsimile thereof covered with a fabric venting network and an overlying layer of elastomeric material. The assembly is cured in the same manner as when tire retreading is effected utilizing precured tread material. After curing, the thus formed flexible matrix with the incorporated venting material is removed and is used in retreading tires prepared in the same manner as in the case where rigid external molds are used but with the curing of the assembly effected in the same way the flexible matrix was prepared.
