REMARKS: Liner stock apparently extends from 0.15 in. above heel on one side to 0.15 in. above heel on other side and is approx. 0.029 in. in thickness at crown. Minimum innerliner gauge is 0.026 in. at shoulder. Liner splice is on an approx. 90 degree angle. Gum layer under ply1 is approx. 0.019 in. in thickness at crown and apparently extends from 0.40 in. above toe on one side to 0.40 in. above toe on other side. Each shoulder has a wedge stock over the top ply which extends approx. 0.60 in. under the first belt edge. Venting: Inside of tire has angular vents spaced approx. 0.25 in. apart at bead. Vents are approx. 4.50 in. long, approx. 0.07 in. wide and approx. 0.01 in. raised and are part of a molded vent pattern (see section). Tread mold is divided into 8 radial segments. Treadwear indicators are marked with 6 triangles around the shoulder of the tire.
