STICKER: NONEREMARKS: Tread and black sidewall are of different stock. 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. 0.037 in. inthickness at crown. Minimum inner liner gauge is 0.029 in. at shoulder. Liner splice is onan approx. 90 deg. angle. Each shoulder has a wedge stock over the ply which extendsapprox. 0.75 in. under the first belt edge. Tread has a total of 72 pitches. Tread mold isdivided into 8 radial segments. Each sidewall has a thin gum strip between the liner andthe ply which extends down from the shoulder area and is approx. 2.00 in. in length. Venting: Inside of tire has angular vents spaced approx. 1.60 in. apart at bead. Ventsextend from toe on one side to toe on other side, are approx. 0.10 in. wide and approx.0.03 in. raised and are part of a molded vent pattern (see section). Raised blackletters: approx. 0.65 in. in height and approx. 0.01 in. raised. Serrated outlinedraised black letters: approx. 0.35 in. to approx. 0.55 in. in height and approx. 0.02 in.raised. Treadwear indicators are marked with 8 Michelin Man logos around the shoulder ofthe tire.
