Mold for vulcanizing radial tires and having fixed and movable sidewall matrices with radially movable tread forming matrices. Tread segments are carried by an annular piston housed within a chamber in the mold body. The chamber is closed by a member guiding the piston and sealing the mold cavity when the press is closed. Fluid pressure introduced into the chamber actuates the piston for selective radial movement of the tread forming matrices.
