Specifications include, but are not limited to: Those retread procedures wherein the curing (vulcanizing) of the tread to the worn and prepared casing is done at 210° using a pressure chamber, tires mounted on curing rims for inflation to a pressure 30 psi higher than the pressure within the chamber, encapsulation of the tire exterior by means of an envelope sealed at the curing rim edge and exhausting air from between tire and inner face of the envelope to the atmosphere. Those retread systems wherein the vulcanization of tread to casing is performed at 220°F thru 325°F within a pressure vessel or matrix. Each retread facility bidding on retreading should have in the shop area, and be able to demonstrate usage, a complete shop manual which fully describes established procedures for initial inspection, repairing, processing, vulcanizing, labeling, and final inspection of the tires being retreaded. If work will not be performed in your shop, indicate the location where the work will be performed. Casings containing any of the following weaknesses or injures must be rejected: 1. Ply separation 2. Broke, kinked, damaged, or exposed bead wire 3. Injuries to the body plies in the bead area 4. Flex breaks 5. Loose cords on the inside ply or evidence of having been run underinflated or overinflated 6. Tread separation and ply separation 7. Weather checking extending to the body plies 8. Non-reparable damage to the inner liner or bead sealing areas on tires identified as tubeless 9. Tires worn to the body plies on more than 10% of the worn tire circumference...
