REMARKS: Liner stock apparently extends from 0.80 in. above toe on one side to 0.80 in. above toe on other side and is approx. 0.040 in. in thickness at crown. Minimum innerliner gauge is 0.040 in. at center and shoulder. Liner splice is on an approx. 89 degree angle. Each sidewall has thin strip located between the liner and ply 1 which extends down from the shoulder area and is approx. 2.30 in. in length. Venting: Inside of tire has angular vents spaced approx. 0.30 in. apart at bead. Vents crisscross to form an "X" pattern on both sides of the tire, are approx. 8.05 in. long, approx. 0.05 in. wide and approx. 0.01 in. raised. Tread mold is divided into 8 radial segments. Treadwear indicators are marked with 6 triangles around the shoulder of the tire.
