Tread Builder Expandable rim width of 14.5 inches is required. Buffing on a more narrow rim can result in excess undertread remaining in the shoulder, increasing the operating belt edge temperature. Tread building should not begin until tire pressure has reached the target inflation pressure in the expandable rim as defined by your retread process manufacturer. For cushion to casing extruded bonding gum application, recommended minimum inflation pressure is 0.8 bar or 12 psi. Bonding gum thickness should not exceed 1.5 mm (2⁄32") in the crown and 2.5 mm (3⁄ 32") in the shoulders.
