Abstract
A method of reducing rubber projections such as vents and flash formed during molding and vulcanizing of a pneumatic tire by prior treatment of selected outer surfaces of the tire with from one to ten megarads of electron radiation from a 500,000 to 3,000,000 KV source to inhibit the flow of the treated rubbery material into the vent holes of the mold and crevices between abutting sections of the mold.
