REMARKS: Tread is superimposed on subtread. Liner stock apparently extends from 0.60 in. above toe on one side to 0.60 in. above toe on other side and is approx. 0.046 in. in thickness at crown. Mimimum innerliner gauge is 0.041 in. at shoulder. Liner splice is on an approx. 88 degree angle. Gum layer under ply is approx. 0.024 in. thickness at crown and apparently extends from heel on one side to heel on other side. Each shoulder has a wedge stock over the ply which extends approx. 0.65 in. under the first belt edge. Venting: Inside of tire has angular vents spaced approx. 0.35 in. apart at bead. Vents are approx. 8.00 in. long, approx. 0.05 in. wide and approx. 0.02 in. raised. Treadwear indicators are marked with 6 triangles around the shoulder of the tire.
