MRT Pre-Mold retreads are double vacuum enveloped. Double enveloping means that all surfaces of the casing and tread - inside and out, bead-to-bead - are subject to uniform mechanical pressure which promotes full integration of repairs. Enhanced temperature distribution reduces "cool" spots and greatly reduces over-curing. MRT Pre-Mold retreads are cured to Michelin protocols for time, temperature, and pressure. Typical pre-cure plants use only a single outer envelope and sealing rings around the beads, with large temperature variations inside the curing chamber.
