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 0.20 in. above heel on one side to0.20 in. above heel on other side and is approx. 0.020 in. in thickness at crown. Minimuminner liner gauge is 0.020 in. at center and shoulder. Liner splice is on an approx. 89deg. angle. Tread has a total of 31 pitches. Tread mold is divided into 9 radial segments. Gum layer under ply 1 is approx. 0.025 in. in thickness at crown and apparently extendsfrom 0.60 in. above heel on one side to 0.60 in. above heel on other side. Venting: Inside of tire has angular vents spaced approx. 0.20 in. apart at bead. Vents crisscrossto form an "X" pattern on both sides of the tire, are approx. 7.50 in. and approx. 6.40in. long, approx 0.05 in. wide, approx. 0.01 in. raised and are part of a molded ventpattern (see section). Outlined raised black letters: approx. 0.45 in. in height,approx. 0.02 in. raised and approx. 0.02 in. outlined. Treadwear indicators are markedwith 6 triangles around the shoulder of the tire.
