420/70-28 Alliance AF 670 140A8 / 137B

AF670 is a wide-base radial tire developed for modern and high-power tractors on the heavy- duty field and hauling applications. Special R1-W traction tread pattern, radial nylon casing, rigid belts, mudguard, and unique shoulder design ensure excellent grip and high traction efficiency. The large tire footprint area reduces average ground pressure, minimizing soil compaction and increasing flotation abilities. Strong nylon carcass, rigid belts, and endurance tread rubber compound provides long tire life.
