REMARKS: Tread is superimposed on subtread. Liner stock extends from toe on serial side to 0.05 in. above toe on non-serial side and is approx. 0.034 in. in thickness at crown. Liner splice is on an approx. 81 degree angle. Each sidewall has a thin rubber strip located between the liner and the ply which extends down from the shoulder area and is approx. 2.40 in. in length. Venting: Inside of tire has angular vents spaced approx. 0.20 in. apart at bead. Vents are approx. 5.70 in. long on serial side and 5.20 in. long on non-serial side, approx. 0.07 in. wide and approx. 0.02 in. raised and are part of a molded vent pattern (see section). Tread mold is divided into 9 radial segments. Treadwear indicators are marked with 6 TWI around the shoulder of the tire.
