STICKER: NONEREMARKS: Tread is superimposed on subtread. Tread and black sidewall are of different stock.

Subtread and black sidewall apparently of different stock. Subtread and tread apparentlyof different stock. Liner stock apparently extends from 0.95 in. above toe on one side to0.95 in. above toe on other side and is approx. 0.025 in. in thickness at crown. Minimuminner liner gauge is 0.025 in. at center and shoulder. Liner splice is on an approx. 87deg. angle. Each shoulder has a wedge stock over the top ply which extends approx. 0.30in. under the first belt edge. Venting: Inside of tire has angular vents spaced approx.0.40 in. apart at bead. Vents are approx. 7.60 in. long, approx. 0.10 in. wide and approx.0.02 in. raised and are part of a molded vent pattern (see section). Tread has a total of70 pitches. Tread mold is divided into 8 radial segments. Gum layer under ply 1 isapprox. 0.028 in. in thickness at crown and apparently extends from 0.85 in. above toe onone side to 0.85 in. above toe on other side. Outlined pebbled black letters: approx.0.40 in. to 0.90 in. in height, approx. 0.04 in. raised and approx. 0.02 in. outlined. Treadwear indicators are marked with 6 T.W.I. around the shoulder of the tire.
