Abstract
A plurality of solid tires are retreaded simultaneously in a stacked configuration in an autoclave or the like. Each tire periphery is provided with a U-shaped cover which engages and seals with the rims or shoulders of the tire. The sealing is effected by placing rigid plates between tires and compressing the stack vertically with an internal tension device, the edges of the envelopes being compressed between the plates and the respective tire rims or shoulders.
