ABSTRACT:
A laminar “precured” or “replacement” tread for wheeled vehicles operating at night on retreaded tires is made more readily visible when grooves in the tires are provided with elastomeric strips or bands in which are embedded retroreflective elements such as transparent glass or synthetic resinous microspheres (referred to herein as “beads”). Upper surfaces of longitudinal ridges in a flat curing mold lend themselves to supporting the strips which are then precisely positioned in grooves defined by the ridges, when the flat tread is cured.
