Introducing 7.50R16L Light Truck Radial Tire Design. Structural design: the expansion rate of outer diameter is 1.004, the section wide expansion rate is 1.068, the bead diameter is 404 mm, the horizontal axis position (H1 / H2) is 1.009, and the tread pattern is dominated by two longitudinal grooves , With the zigzag horizontal groove. Construction design: The carcass is made of 3 layers of 1667dtex / 2 high modulus low shrink polyester cord, and the belt is made of 0.365 + 6 × 0.35HT steel cord. Finished tire outer edge size, strength performance, high speed performance and durability meet the design requirements.
